Identify the phase of circulation which is represented in the diagram of heart given below. Arrows indicate contraction of the chambers shown.
(A) Blood transferred to the right ventricle and left ventricle simultaneously.
(B) Blood is transferred to lungs for oxygenation and is pumped into various organs simultaneously.
(C) Blood transferred to the right auricle and left auricle simultaneously.
(D) Blood is received from lungs after oxygenation and is received from various organs of the body.
Answer -
Now,
- When it pumps the blood to the organs, the heart is contracted .
- When it receives the blood from the lungs, the heart is relaxed .
In this figure, contraction in both ventricles is due to the fact that blood is pumping out.
- In the left ventricle, the oxygenated blood is pumping to other parts of the body.
- In the right ventricle, the deoxygenated blood is pumped to lungs for purification of the blood.
Thus, in our case: Blood is transferred to lungs for oxygenation and is pumped into various organs simultaneously.
So, the correct answer is (b)
