D. Oxygenated blood enters the right atrium and is pushed through the bicuspid valve to the right ventricle.

Answers

The answer is B. If I get wrong I'll do it again (in the comments).

The true statement is B. Deoxygenated blood enters the right atrium and is pushed through the semilunar valve to the right ventricle.

Where does deoxygenated blood enters the right atrium?

Deoxygenated blood from the lower half of the body enters the heart from the inferior vena cava while deoxygenated blood from the upper body is delivered to the heart via the superior vena cava. Each the superior vena cava and inferior vena cava empty blood into the proper atrium.

The ventricles are the two lower chambers of the coronary heart. Blood empties into each ventricle from the atrium above, and then shoots out to where it needs to go. The proper ventricle gets deoxygenated blood from the proper atrium, then pumps the blood alongside to the lungs to get oxygen.

The heart has four chambers, right atrium, right ventricle, left atrium, and left ventricle. The deoxygenated blood returns from the body to the right atrium and from there enter the right ventricle that pumps it to the lungs through the main pulmonary artery (pulmonary trunk).

Deoxygenated blood enters the right atrium and is pushed through the semilunar valve to the right ventricle.
