Answer:
The correct answer will be option-A.
Explanation:
The cardiac cycle of the heart is divided into two phases: contraction (systole) and relaxation (diastole).
The atria and ventricles of the heart contract simultaneously in response to the impulse generated in the SA node. The contraction of the atria and ventricles push the blood or pumps the blood.
The atrial systole pumps blood to ventricles whereas the ventricular systole pumps blood to the body parts.
Thus, option-A is the correct answer.

Answer:
The mitral valve has fewer flaps than the right atrioventricular valve:
<em>a) True </em>
Explanation:
The mitral valve is a bicuspid valve, which means it has two flaps; whereas, the right atrioventricular valve is a tricuspid valve and so has three flaps.
These two heart valves link the atrium with the ventricles. The mitral valve is located on the left side of the heart, while the tricuspid valve is on the right side.

The babies who do need these supplements need them due to a lack of sufficient sunlight. Baby has very little exposure to sunlight.
Answer:
