Question

During blood circulation, the heart muscle contracts and the impure blood passes through the heart and lungs, then purified blood flows through a sequential process of:
A. Blood passes into left ventricle
B. Discharges blood into various arteries and capillaries
C. Blood finds its way into left atrium
D. Blood passes into right ventricle
E. Blood finds its way into lungs

• A. (D), (A), (C), (B), (E)
• B. (D), (A), (B), (C), (E)
• C. (D), (C), (B), (A), (E)
• D. (D), (C), (E), (A), (B)

Hint:

Answer 1

The Correct Option is D

The path of blood through the heart and lungs is:

1. Blood enters the right ventricle (D),
2. Moves to the lungs (C) for oxygenation,
3. Returns to the left atrium (E),
4. Enters the left ventricle (A),
5. Ultimately discharged into arteries and capillaries (B).
