Answer 2

Your question is incomplete, but most probably your full question was:

Assertion (H) : The walls of ventricle are thicker than the walls of the auricles.

Reason (R): The ventricles has to pump blood to long distance and various organs.

a. both A and R are true and R is the correct explanation of A

b. both A and R are true and R is not the correct explanation of A

c. A is true but R is false

d. A is false but R is true​

Answer:

The given assertion and reason are true, and the reason gives the correct explanation of the assertion.

Therefore, option a is the correct option.

Explanation:

• The ventricles are the muscular chambers of the heart that play a major role in blood supply. It is divided into two parts: the left ventricle and the right ventricle.
• The left ventricle receives oxygenated blood from the left atrium. And the right ventricle receives the deoxygenated blood from the right atrium.
• Then, the left ventricle pumps oxygenated blood from the heart to the rest of the body, and the right ventricle pumps deoxygenated blood from the heart to the lungs.
• Since the main function of the ventricle is to pump the blood out of the heart, it has to handle greater pressure to transport blood a long distance. Therefore, they have thicker walls than auricles.

Therefore, both A and R are true, and R is the correct explanation of A. So, option a is correct and the rest of the options are incorrect.
