Explanation:

Question 13

The left side of the heart receives oxygen - rich blood from the lungs. The left ventricle then pumps this blood out to the rest of the body to supply oxygen and nutrients. Option A is incorrect because the right side of the heart deals with oxygen - poor blood from the body. Option B is incorrect as systemic veins carry oxygen - poor blood back to the heart, not the destination of the blood pumped by the left side of the heart.

Heart valves are made up of flaps called cusps. Septums are the walls that separate the chambers of the heart, not the flaps of the valves. The endocardium is the inner lining of the heart chambers and valves, not the flaps that make up the valves.

Answer:

C. rest of the body
