Question

Description of each one of them in short answer
Example: Vena cava description: Carries deoxygenated blood from the body to the heart


Semilunar valve



Left atrium



Left ventricle



Pulmonary artery



Right ventricle



Pulmonary vein



Right atrium



Aorta

Answer 1

Answer:

1. Each of a pair of valves in the heart, at the bases of the aorta and the pulmonary artery, consisting of three cusps or flaps which prevent the flow of blood back into the heart.

2. Left atrium: The upper right chamber of the heart. The left atrium receives oxygenated blood from the lungs and pumps it down into the left ventricle which delivers it to the body.

3. The left ventricle is the thickest of the heart's chambers and is responsible for pumping oxygenated blood to tissues all over the body. By contrast, the right ventricle solely pumps blood to the lungs.

4. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration. In contrast to the pulmonary arteries, the bronchial arteries supply nutrition to the lungs themselves.

5. The right ventricle (RV) is the most anterior of the four heart chambers. It receives deoxygenated blood from the right atrium (RA) and pumps it into the pulmonary circulation. During diastole, blood enters the right ventricle through the atrioventricular orifice through an open tricuspid valve (TV).

6. The pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart. The largest pulmonary veins are the four main pulmonary veins, two from each lung that drain into the left atrium of the heart. The pulmonary veins are part of the pulmonary circulation.

7. Right atrium: The right upper chamber of the heart. The right atrium receives deoxygenated blood from the body through the vena cava and pumps it into the right ventricle which then sends it to the lungs to be oxygenated.

8. The aorta is the main artery that carries blood away from your heart to the rest of your body. After the blood leaves the heart through the aortic valve, it travels through the aorta, making a cane-shaped curve that connects with other major arteries to deliver oxygen-rich blood to the brain, muscles, and other cells.
