Question

Why is the heart divided into various chambers?

• A. To ensure the efficient supply of oxygen in the body
• B. To avoid mixing up of oxygenated and deoxygenated blood
• C. To ensure mixing up of oxygenated and deoxygenated blood.
• D. To keep the body warm

Answer 1

Answer: (A), (B)

The correct options are
A To ensure the efficient supply of oxygen in the body
B To avoid mixing up of oxygenated and deoxygenated blood

Both oxygen and carbon-dioxide are transported by the blood. The heart has different chambers to prevent the oxygen-rich blood from mixing with the blood that is carbon dioxide and deficient in oxygen. Also, such a separation allows a highly efficient supply of oxygen to the body. Different chambers have different functions exhibiting a division of labour in the heart.
