Answer 1

Answer:

D. BOTH A & C

Explanation:

Your heart is a hollow muscular organ, about the size of your clenched fist. It pumps blood around the body, delivering oxygen to every organ and cell. The heart lies in the middle of your chest, just behind the breast bone.

Your heart has four separate chambers that pump blood. The chambers are called the right atrium, right ventricle, left atrium, and left ventricle. The right and left sides of the heart are separated by a muscular wall that prevents blood without oxygen from mixing with blood that has oxygen.

Answer 2

D. BOTH A & C is correct about human heart.

1. Human heart is the part of circulatory system. It is involved in pumping the blood to different organs of the body.
2. The heart is divided into four chambers, where right auricle and ventricle receives deoxygenated or impure blood and left auricle and ventricle receives oxygenated blood.
3. The pure and impure blood do not mix with each other due to seperation of these chambers.
