Question

What is 'force pump' in frog? Why is it named so?

Answer 1

An extensive network of blood vessels runs throughout the frog's skin. Oxygen can pass through the membranous skin, thereby entering directly into the blood. When a frog submergesbeneath the water, all its respiration takes place through the skin

Answer 2

Force pump in frog:

• Respiration is a vital process in the bodies of all the organisms, in which the intake of oxygen takes place and it is oxidized in order to release the energy, which is then utilized by the cells to perform regular cellular processes.

• In frogs, breathing systems function uniquely. Breathing is a mechanical process which involves the intake of air into the respiratory organs (inhalation or inspiration).

• The removal of air (exhalation or expiration) by changing the volume of "bucco-pharyngeal cavity", which acts as a 'Force pump'.

• In this mechanism, after the inspiration the nostrils of the frogs are being closed and the air is forced inside the lungs. Hence, the name 'Force pump'.
