Heart anatomy and blood flow. In addition to carrying fresh oxygen from the lungs and nutrients to your bodys tissues. In the lungs the blood picks up oxygen and drops off carbon dioxide before returning to the heart. There are six structures on each of these sides that are used during blood.

Blood flows in the following sequence in the heart. This region of the heart where the left ventricle comes to a p the term refers to heart muscle these are collagen fiber cords that attach heart valves to pap. Blood enriched with oxygen in the lungs.

Blood now moves from the right ventricle through the pulmonary semilunar valve which is the valve that separates the right ventricle and the lungs. The left side and the right side. As we previously learned this is called the pulmonary circuit.

It leaves the left section of the heart and flows through the arteries to distribute oxygen and nutrients to the organism. The vessels are elastic tubes that carry blood to every part of the body. Heart valves are controlled by pressure changes within each chamber and contraction and relaxation are controlled by the hearts conduction system.

As the heart beats it pumps blood through a system of blood vessels called the circulatory system. Superior vena cavainferior vena cava right atrium tricuspid valve right ventricle pulmonic valve pulmonary artery lungs pulmonary vein left atrium bicuspid valve left ventricle aortic valve aorta.
