Question

identify the pathway of blood through the heart.

Explanation:

The question is asking to describe the route that blood takes as it passes through the heart. This involves knowledge of the heart's anatomy and blood - flow patterns.

Answer:

Blood enters the right atrium from the body via the superior and inferior vena cava. It then passes through the tricuspid valve into the right ventricle. The right ventricle pumps the blood through the pulmonary valve into the pulmonary artery to go to the lungs for oxygenation. Oxygen - rich blood returns from the lungs via the pulmonary veins into the left atrium. It passes through the mitral valve into the left ventricle, and the left ventricle pumps the blood through the aortic valve into the aorta to be distributed to the rest of the body.
