Question

Why is the heart divided into various chambers?

• A. To ensure an efficient supply of oxygen in the body
• B. To prevent oxygen-rich blood from mixing with carbon-dioxide rich blood.
• C. Both a and b
• D. Neither a nor b

Answer 1

The correct option is C

Both a and b

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 containing carbon-dioxide. Also, such separation allows a highly efficient supply of oxygen to the body. Different chambers have different functions exhibiting division of labour in the heart.
