__ THE CIRCULATORY SYSTEM __



__Primary Function:__ The circulatory system has one primary function, and that is to circulate the blood throughout all of your body. Have you ever been on the highway? That is how the blood travels to all of the body to carry different things. There are 3 main blood vessels in the body. The capillaries- the smallest blood vessels, the arteries- they carry things away from the heart, and the veins- blood returning to the heart. There are two loops that the blood makes. Loop one is heart, lungs, and heart. The second loop is heart, body, and heart. The oxygen from the lungs goes into the blood, and the carbon dioxide from the blood goes into the lungs. All of this is the work of the cardiovascular system. It connects/links all parts of your body, and contains the heart, blood vessels, and blood. Although there is only one primary function, it is the most important, because without a primary function in each system, we wouldn’t be here. To see my web, click here!

__Organs:__ When people draw hearts, they think about love. But that isn’t really where those feelings come from, and it certainly isn’t what the heart looks like. The heart is a hollow muscular organ that pumps blood to the body that is about the size of your fist. The right and left sides of the heart are separated, and each has 2 chambers. The top chambers are called the atria, and the bottom chambers are called the ventricles. The heart is actually 2 pumps in one because of when it pushes blood out, and when it fills with blood. When the heart relaxes, the heart fills with a ton of blood, and when it contracts, it pushes the blood forwards. This process doesn’t take long at all, and it happens all the time. Your heart always works a lot to keep you safe and healthy. To see my poster, click here! To see a video of the heart, click [|here]!

__Other Systems That Work With My System:__ All the systems work together, even if it doesn’t seem like it. The circulatory system works with all the other systems, and this is how. To work with the excretory system, this is what happens. The blood coming from the arteries goes into the kidney, where it leaves the waste it doesn’t need. When it finishes leaving the waste, the blood goes back into the veins and into the heart. To work with the digestive system, the small intestine breaks down all the food, and the nutrients from it flow into the veins, so that it can turn it into energy. The adrenal glands from the endocrine system make adrenaline, and that makes the heart pump faster, and makes the oxygen flow around the body through the blood faster. The bones from the skeletal system store nutrients, and when the body needs them, it releases them into the blood. Apart from this, in the bones, the red blood cells are created, which then become part of the circulatory system. The circulatory system is connected to the immune system because of the blood. The blood contains the things that are in the immune system. The heart is actually a muscle, so that means it connects to the muscular system. The capillaries on the alveoli lungs give oxygen to the blood. That is how the respiratory system connects to the circulatory. The nervous system controls how the blood flows, so that’s how they connect. To see an article on the circulatory system, click [|here]!

__Health:__ There are many diseases it he human body, but also many ways to prevent these diseases and to keep healthy. One disease that has to do with the circulatory system is getting a heart attack. Here is what causes a heart attack. When you eat a lot of junk food, and things that aren’t healthy for you, you are creating fatty deposits. Fatty deposits can make the inside of your blood vessels narrow. When the blood vessels become narrow, blood cant reach the heart, and that is what causes a heart attack. Another disease would be the mitral valve prolapse. This is when the flaps in your h eart are too big or floppy. What happens when they’re like that is that the blood can leak back into the left atrium. It’s actually easy and simple to stay safe and healthy. You have to eat healthy foods (fruits, vegetables, grains), and to always get a lot of exercise. There are many diseases for each system, but many more ways to prevent you from getting them. To see my bibliography, click here!
