CIRCULATORY SYSTEM THE HEART CIRCULATORY SYSTEM BLOOD BLOOD VESSELS HEART The flow of blood through your heart is simple to understand. First the blood flows through your right atrium and then through your left ventricle. Next, it flows to the lungs and receives oxygen. After the blood is oxygen rich, it travels back to the heart but on the left side this time. It enters the atrium, flows to the ventricle and is pumped to the upper and lower body. When the blood is pumped through the rest of the body it gives the cells oxygen and picks up the carbon dioxide. The blood then travels back to the heart and does the cycle all over again. It takes less then a minute to take that trip. Some things that are important about the heart are that arteries take the blood from your heart to your lungs if it is oxygen poor. If not then the blood goes all over your body. Also veins bring the blood make to your heart. The average adult’s heart is 14cm long and 9cm wide. The structure of the heart is simple to understand.There are four chambers in the heart. They are the left atrium, left ventricle, right atrium, and right ventricle. The heart is a strong muscle. This muscle is called the Cardiac Muscle and it never gets tired. Valves in your heart are there so your blood does not flow backwards.
