Muscles

If you didn't have muscles you wouldn't be able to move any part of your body because your muscles are attached to your bones and that lets you move. There are more than 600 muscles in your body. You control some of your muscles and some of them are like your heart which just do there job on their own without you reminding them to. All muscles are made out of a type of tissue. You have three different types of muscles in your body. They are smooth muscles, cardiac muscles and skeleton muscles. You can't control smooth muscles you brain tell the muscle what to do. the smooth muscles are working all around your body and you don't even notice. Smooth muscles are also in your bladder. They allow you to hold urine (pee) until you go to the bathroom. So now you know that muscles are an important part of your body!

Skeleton

Once there was a boy and he (and his class) was studding about the skeleton and the bones. He found out that there are many bones in your skeleton. Soon he knew that there are 206 bones in an adults body. He was interested on finding out that a bone is made out of. The surface of the bone is called the periosteum. The layer after that is made out of compact bone. A compact bone is smooth but very hard. After that there are many layers of the cancellous. Cancellous is not as hard as the compact bone but the bone is very strong. Now the boy found this very interesting. The thing was that in most bones the cancellous protects the most inner part of your bone called the bone marrow and the bone marrow's job is too make blood cells. The boy had a very interesting session with his class about the skeleton and bones and then he told everyone everything he knew about bones.

X-Rays

Do you know what takes a picture of you body?

Have you ever have to have an X-Ray? An X-Ray is photos of your body. They are usually used for seeing if you have broken a bone or to see if you have dislocated a joint. In an X-Ray the air turns out to be black and the bones turn out to be white. So if you have to take an X-Ray of your lungs (and you are not a smoker) and the lungs are black. Don’t think your lungs are really polluted! A technologist is the person who is trained and knows how to take a picture of an X-Rays. So you better do what he tells you to do! When you will take an X-Ray the technologist will tell you to stay very still and not to breath for a few seconds as the X-Ray is being taken. The technologist tells you to do that because if you do maybe the X-Ray that comes out will be bleary. Usually taking an X-Ray is uncomfortable because of the cold room and maybe you will be standing, sitting or lying down in an awkward position. The technologist will find the most comfortable position for the X-Ray to be good quality but still the best position still might not be comfortable! So now you know what to do if you ever need to take an X-Ray!

The Skeletal and Muscular System

The Skeletal and Muscular System is the system about the muscles and skeleton. The skeleton is the basic frame work of your body. Some of the parts in your skeletal-macular system are muscles, skeleton, ligaments and cartilage. Ligaments and like rubber bands that hold two muscles together. Sometimes people tear a ligament and that can sometimes happen because you haven't stretched. Stretching is very importuned because if you haven't stretched your ligaments get a shock and they tear apart. That is very painful but you can just have them back together by warping yourself a kind of bandage. Cartilage is a very soft bone. You can fell some of your cartilage in your ear. If you didn't have muscles than you would not be able to move any part of your body where there is a bone. Now go ahead and read about the Skeleton and Muscular System!

Smoking

Smoking can harm some of the parts in your body. One of the parts smoking can harm is your lungs. Smoking cigarettes causes a lot of changes in you airways. Cigarets is made out of tobacco leaf and the leaf might not seem harmful at all but hen the tobacco is burning there are more than 4,000 chemicals in the cigarette. The cigarette has a chemical that can make normal cells into cancer cells. There is a cleaning system in your lungs and when you smoke cigarettes the cleaning system slows down. The cilia cleans your lungs and when you smoke the cilia can slow down for a few hours. Smoking also reduces some of your cilia's and then you have less cilia's in your lungs. So that means you have less cleaners in your lungs. When you smoke the tissue in your lungs in destroyed so you have less air sacks and blood vessels in your lungs because of that less oxygen in carried around your body. You can harm your lungs without smoking. you harm your lungs when other people are smoking near you. That is called second hand smoke. Some people want to quite smoking but they can't because smoking is very addictive and you just can't sop even if you want to however, there are some people who have stopped smoking and that could be the most important thing you have done in your life.

Second Hand Smoke

Bonchitis

Once there was a boy and he had a very bad cough with a rasping noise. He could not sleep or eat. So he went to the doctor. The doctor took out his stethoscope and checked whether he had any wheezing because to check if his chest was clear. the doctor found out that he did have a wheezing noise and then he knew that he had bronchitis. The doctor explained "Bronchitis is when the germs cause your bronchioles to swell up so that there is not enough space for air to pass this results in coughing. i will give you this medicine to eat every day and then you will be fine".

Lungs

The lungs have a very important part to play in the respiratory system. There are two lungs in your body the right lung is in the right side of the heart and left is in the left side of your heart. So they surround the two opposite sides of the heart. The lungs main job is to put the oxygen into the blood. Once the air goes through the mouth or nose, it travels through the pharynx (another name for throat), nasopharynx and the trachea (wind pipe), and the air also goes through the bronchi and bronchioles (small tubes) until it finally reaches the alveoli where the air is exchanged of carbon dioxide and oxygen. Now let’s talk about some number facts about the lungs. About 90% of the lungs are made up of air and only 10% is made up of hard tissue. A male’s average of how much one of the lungs weight is 1060 grams and female’s average of how much the lung weight is 930 grams. Some more amazing facts about the lungs are at least one liter of air stays in your lungs no matter how hard you breathe out. Each lung is about 10-12 inches long. In an average persons life a person takes about half a billion breathes. If all the different sized tubes in the lungs were connected and stretched out they would go more than 50 kilometers! In both lungs of an adult there are about 300 million alveoli! Do you smoke? Smoking is very addictive and smoking is very harmful to your lungs and some other parts of your body. Do you want to keep your lungs healthy or are you already keeping your lungs healthy? Well if you want to the simplest way to keep your lungs healthy is just to exercise often. Just keep on exercising at least 2-3 times a week and you will have a long!

The Respiratory System

The Respiratory System is a system about breathing in oxygen and breathing out carbon dioxide. Some of the parts in the respiratory system are nose, mouth, tracheae, bronchi and lungs. The air taken in of through the nose passes through the bronchi into bronchioles that line the entire surface of the lungs. Oxygen from the air diffuses into the blood and carbon dioxide from the blood diffuses out. Any obstruction in the air passage leads to a response by the body such as sneezing or coughing. So now go ahead and read about the respiratory system!

Blood Vessels

Do you know that you have blood vessels in your body? Well you do. You have lots of them. They are tubes which blood flows through. There are three different blood vessels in your body. The three blood vessels are Arteries, Veins and Capillaries. Arteries are the biggest blood vessels in your body, Veins are smaller than Arteries but still not the smallest and Capillaries are the smallest blood vessels in your body. Arteries carry blood away from the heart and every where in the body and the blood that flows through the Arteries is bright red because the blood has oxygen. The blood has been through the heart and lungs that’s where the blood gets the oxygen. Veins carry blood back to the heart and lungs to get more oxygen. The blood that flows through Veins is blue because the blood has no oxygen. No one knows why blood becomes blue after the blood has no oxygen and no one knows why the blood becomes red when the blood has oxygen. Capillaries are tiny blood vessels that make a kind of a tunnel for your blood to get from your Arteries to your Veins. When you bleed a bit you are destroying around fifty of your Capillaries not your Veins or Arteries. Do you know how long your Arteries, Veins and Capillaries would go if you stretched them and connected them? Well in an adult body they would circle the planet Earth three times! Do you think your blood flows slowly through your body or dose the blood go fast? The answer is your blood circulates your body quite fast. Your blood only takes one minute to circulate all around your body! The longest Blood Vessel in your body is an Artery and the Arteries name is Aorta. Well now you know about blood vessels and any second you can try to picture your blood flowing smoothly and fast trough your blood vessels! You can also try to picture how many blood vessels you have and how do they fit in you body (remember they will circle the planet Earth three times)?

White Blood Cells

Have you ever wondered what kills all your germs in your body? They are white blood cells that kill the germs in your body. White Blood Cells are like solders or police man of your body. When germs get into your body they duplicate them and become from 1 to two white blood cells and soon their could be thousands of white blood cells. So when you become a bit sick all you have to do is rest and sleep often. If you just do that your white blood cells will probly be able to kill the germs in your body without any use of medicine however, sometimes they are not able to kill the germs and then you have to take medicine. Medicine is just like a boost to the white blood cells. That is why you have to eat medicine sometimes. So keep on resting when you are sick and just let your white blood cells do their job!

Blood Pressure

Blood Pressure is the pressure that the blood gives on the wall of the arteries as the blood flows through the artery. There are two kinds of pressure-diastolic pressure and systolic pressure. The normal blood pressure in an human adult is 120/80 millimeter. The pressure should not increase or decrease too much as too high or too low blood pressure can be life threatening. If you eat too much salt your blood pressure can go up. You don't need to worry about your blood pressure too much because if you are just normal nothing will happen to you.

White Blood Cells, Red Blood Cells, Platelets and Plasma

Once there was a boy who was looking at a book about the things in your blood. He found out that the things in your blood are red blood cells, white blood cells, platelets and plasma. He was so exited he kept on reading the book. He found out that red blood cells are like trucks that carry oxygen to every cell in your body and that there are so many red blood cells your blood becomes red. He found out that white blood cells are like solders of your body and they kill germs so you do not get sick. He read that white blood cells flow through your blood as well as red blood cells. Then he found out about platelets. He now knew that platelets come rushing to the place you are bleeding and they make a thing that makes you stop bleeding. Their job is only a few seconds long. Finally he read about plasma. Plasma is a liquid that red blood cells, white blood cells and platelets travel through. He found out about a lot of things in the book and he couldn't wait to tell his friends about red blood cells, white blood cells, platelets and plasma.

Anemia

One day an old man came to the hospital. He says to the doctor "I feel so tired all the time these days. Is there anything wrong with me or am I getting just too old?"

"I think you have anemia. Anemia is a disease in which you feel tired because your red blood cells are not as strong as they should be and they just can't carry as many oxygen as they should. You also have not as many red blood cells as you should have so that makes their job really difficult.

There are a few ways to keep your red blood cells healthy. You should just eat iron food and exercise often. Iron food is good because that increases you red blood cells and that is good. Exercise will just keep your red blood cells strong and hopefully they will become stronger in the future"

The Heart

The heart is the strongest muscle is your body. Your hearts only has one job and the job is to pump blood. The heart is also one of the most importuned part of your body because the second your hearts stops beating and the second your hearts stops pumping blood you will die. The heart has four chambers. They are called the right atrium, left atrium, right ventricle and the left ventricle. The atriums are at the upper part of your heart and ventricles are in the lower part of your heart. Another thing in your heart is your valves. Valves are small parts in your heart that let the blood flow through one chamber to another chamber. When you hear your heart beat you are hearing your valves open and close. In a day the your heart pumps around 1,900 gallons in 24 hours! One way to harm your heart is eating lots of fatty food. Fatty food sticks to your heart and that makes a harder job for the heart to pump the blood. If the fatty food sticks to your valves then the blood just stays in one of the atriums or ventricles. If that happens you might need to have a operation which is quite serious. So do you want to keep your heart healthy? That is really easy. Don't eat too much of fatty food all the time. You can eat fatty food once a meal but just don't eat too much. Another way to keep your heart healthy is to exercise quite often. If you just keep on doing these two way to keep your heart healthy you will be healthy and fit for the rest of your life!

The Circulatory System

The circulatory system is about the circulation of the blood through the network of blood vessels. The circulatory system includes the heart and the blood vessels. There are three different blood vessels in your body and they are arteries, veins and capillaries. Capillaries are very fragile so they can be destroyed easily. When you get a small scratch and you bleed a bit you are destroying around 50 of your capillaries (which doesn't matter). Destroying an artery or a vein is really rare. You can't destroy them when you get a small scratch and you don't destroy them even when you get a deep cut as well. Arteries carry oxygen to ever cell in your body and the veins carry blood back to the heart to get more oxygen. The heart is the most important part in the circulatory system because if the heart stops to pump blood you will die. Your heart keeps on pumping blood and pumping blood till you are dead. So move ahead and read everything about the circulatory system which promises to be an very interesting system!
