A sleep

When your foot, your Hand or etc. is fell a sleep from staying in one position a long time, that means that your vein or artery squeeze together and your blood has a hard time flowing through it. It has this wirde felling. When that happens I would segest to stamp your foot or shake it all around. If that dosen't work ask someone to see if thei now, but try it for a long time.

Functions of the circulatory system

You would probably guessed that the blood just doesn't slosh around your body once it leaves the heart. It moves through many tubes called arteries and veins, which together are called blood vessels. These blood vessels are attached to the heart. The blood vessels that carry blood away from the heart are called arteries. The ones that carry blood back to the heart are called veins.

The movement of the blood through the heart and around the body is called circulation (say: sur-kyoo-lay-shun), and your heart is really good at it — it takes less than 60 seconds to pump blood to every cell in your body.

Without oxygen, these cells would die and I don't think you'd live without them. If that oxygen-rich blood doesn't circulate as it should, a person could die.

The left side of your heart sends that oxygen-rich blood out to the body. The body takes the oxygen out of the blood and uses it in your body's cells. When the cells use the oxygen, they make carbon dioxide and other stuff that gets carried away by the blood. It's like the blood is the cells servant and delidelivers lunch to the cells and then has to pick up the discussing trash!
The returning blood enters the right side of the heart. The right ventricle pumps the blood to the lungs for a little freshening up. In the lungs, carbon dioxide is removed from the blood and sent out of the body when we exhale means to breath out and the opposite is to inhale ( to breath in). What's next? An inhale, of course, and a fresh breath of oxygen that can enter the blood to start the process again. And remember, it all happens in a minute or less!

The Parts of the Circulatory System

    The circulatory system has a lot of parts and organs. I'm going to tell you some of them. 

     One of them and definately the most important part is the heart. There are also the veins and arteries which are kind of like two long tubes that go through the system. There is also the blood vessels which pumps oxygen out of the heart. There are two platelets the white platelets and the red platelets, the white platelets only come about once every one thousand red platelets. If you have a lot of platelets and your blood type is "o" than you can give them to people who need them. The plasma which is the liquid part of blood carries all the blood cells, it is made in the liver.

            I hope you liked learning about the parts of the circulatory system. I enjoyed teaching you about the parts.

The Circulatory System rocks!

Health Issues for the Circulatory System

There are a lot of types of problems you can have in your heart. There is Arteriosclerosis (say ar-teer-ee-oh-skluh-row-sus) in an easier way to say it hardening of the arteries. It means your arteries are thick and aren't flexible anymore. Or there is Atherosclerosis (say ah-thuh-row-skluh-row-sus) people that have this have a buildup of cholesterol and fat so that their arteries are more narrow so less blood gets through. Their is also Angina (say an-jy-nuh). When people with angina feel pain in their chest it means that their heart isn't getting enough blood. Then most people know Heart Attack. This is when there is a blood clot or blockage and it cuts blood from getting to that part of the heart. And their is Stroke. It is when the brain doesn't get enough blood because of a clot or a blood vessel burst. As kids most people don't get any of those. And you can prevent other things by not smoking, eating well, exercising, and having a healthy weight. If have healthy habits then you probably won't need to worry about any of these if you treat your body healthy and don't smoke or do drugs. And if you do smoke it is hard to quit but if you manage to quit doing drugs or smoking, your friends, family, lungs, heart, body, and the rest of the people around you will thank you. And if one of your friends try to give you a supposedly harmless little cigarette or drug just walk away and again you will be more happy.
