Question

The nurse is teaching a client with cardiac disease about the anatomy and physiology of the heart. Which is the correct pathway of blood flow through the heart?

A) Right ventricle, left ventricle, right atrium, left atrium
B) Left ventricle, right ventricle, left atrium, right atrium
C) Right atrium, right ventricle, left atrium, left ventricle
D) Right atrium, left atrium, right ventricle, left ventricle

Answer 1

The correct pathway of blood flow through the heart is from the body to the right atrium, right ventricle, pulmonary artery, lungs, pulmonary veins, left atrium, left ventricle, and aorta.

Step-by-step explanation:

The correct pathway of blood flow through the heart is:

1. Blood from the body enters the right atrium of the heart.
2. The right atrium pumps the blood to the right ventricle.
3. The right ventricle pumps the blood to the pulmonary artery, which carries the blood to the lungs.
4. In the lungs, the blood picks up oxygen and gets rid of carbon dioxide.
5. The oxygenated blood returns to the heart through the pulmonary veins.
6. The blood enters the left atrium and is pumped to the left ventricle.
7. The left ventricle pumps the blood to the aorta, which is the main artery of the body.
8. The aorta carries the oxygenated blood to the rest of the body.
