Question

Describe the path of blood through the heart.

Answer 1

Blood enters the heart through the right atrium and is pumped to the lungs for oxygenation before returning to the heart and being pumped to the rest of the body.

Step-by-step explanation:

The path of blood through the heart starts with deoxygenated blood entering the right atrium from the body through the superior and inferior vena cava. The right atrium pumps the blood to the right ventricle, which then pumps it to the lungs through the pulmonary valve and artery. In the lungs, the blood picks up oxygen and returns to the heart via the pulmonary veins, entering the left atrium. The left atrium pumps the oxygenated blood to the left ventricle, which then pumps it to the rest of the body through the aorta.

Answer 2

Blood enters the heart through the superior and inferior vena cava. These two paths dump deoxygenated blood into the right atrium. Blood passes from the right atrium through the tricuspid valve into the right ventricle. The right ventricle contracts and forces the blood through the pulmonary semilunar valve into the pulmonary arteries.
