• D. Pulmonary Circulation: Right Ventricle $\to$ Body $\to$ Left Atrium

Answer 1

Answer: (B), (C)

The correct options are
B

Pulmonary Circulation: Right Ventricle $\to$ Lungs $\to$ Left Atrium

C

Systemic Circulation: Left Ventricle $\to$ Body $\to$ Right Atrium

Double circulation includes pulmonary and systemic circulation. In the pulmonary circulation, blood circulation starts from the right ventricle to the lungs and from there to left atrium. In the systemic circulation, the circulation starts from the left ventricle and ends in the right atrium after circulating throughout the whole body.

Pulmonary Circulation: Right Ventricle $\to$ Lungs $\to$ Left Atrium

Systemic Circulation: Left Ventricle $\to$ Body $\to$ Right Atrium
