Question

() What is the advantage of separation of oxygenated blood from the deoxigenated
blood?
(a) It allows a mixed supply of blood in the body.
(b) It removes deoxygenated blood from the body.
(c) It allows a highly efficient supply of oxygen to the body.
(d) All of these​

Answer 1

when the oxygenated and deoxygenated blood are separated, then their mixing doesn't takes place . it is useful for more efficient transport of blood because oxygen enriched blood is only transferred to the required cell. it is helpful in organisms who have higher rate of metabolism.

Option (C)

Answer 2

Answer:

c) It allows a highly efficient supply of oxygen to the body.

Explanation:

1) The oxygenated blood is separated from the deoxygenated blood, which improves the efficiency of double circulation and is probably required for the warm-blooded lifestyle of mammals and birds. The four-chambered heart of birds and mammals evolved independently from a three-chambered heart.
