Question

The oxygenated and the deoxygenated blood in the chambers of the heart do not mix at any point of time.

• A. True
• B. False

Answer 1

The correct option is A

True

Deoxygenated blood coming back to the heart from other areas of the body enters into the right side of the heart and goes into the lungs. Blood that has been oxygenated by the lungs enters into the left side of the heart and is pumped back out into the body. Hence the oxygenated and the deoxygenated blood in the chambers do not mix at any point of time.
