Question

Respiratory system of cockroach is formed of spiracles and tracheal interconnections. Why is it said to be more efficient than that of earthworm? Why inspiration of cockroach is said to be a passive process while it is an active process in man?

Accepted Answer

The respiratory system of cockroach is formed of spiracles and tracheal interconnections but it said to be more efficient than that of an earthworm because it gives direct contact to the oxygen whereas earthworms respire through the skin by diffusion which is a time taking process.

The inspiration of cockroach is said to be a passive process while it is an active process in humans because, in cockroaches, the air which is inhaled is directly coming in contact with the various body organs. In humans, the oxygen indirectly reached all the body parts through the heart and blood.
