Question
What is the difference between baccopharangeal and pulmonary respiration in frogs
Open in App
Solution
1. Buccopharyngeal respiration
· The respiration through the buccopharyngeal cavity is called buccopharyngeal respiration.
· The buccal cavity consists of moist mucous membrane and richly supplied with blood vessels.
· The air enters into the cavity through nares and gaseous exchange takes place through the lining of buccal cavity between blood and air present in the cavity.
Buccopharyngeal respiration occurs through the lining of the mouth. This only occurs when the frog is not submerged in water.
The lining of the mouth is very moist and can be used to bring oxygen into the bloodstream by dissolving it and diffusing it into the
blood capillaries, in a similar way to the skin respiration system.
2. Pulmonary respiration
· The respiration through the lungs is called pulmonary respiration.
· This respiration occurs only when the need of oxygen is more during swimming and jumping.
· There is a pair of lungs. The lungs are thin walled elastic sacs. They are present within thoracic cavity on either side of heart.
· Numerous small air sacs are present in the lungs called alveoli.
· The alveoli are very thin walled and supplied by blood vessels. The air enters into the alveoli of the lungs through the external nares, internal nares,
buccopharyngel cavity, glottis, laryngotrachial camber, and bronchi.
Frogs' lungs are comparatively underdeveloped and are not used all the time. As they have no diaphragm to help regulate air pressure in the lungs,
they use their mouth, gullet and nostrils to push the air in and out of the lungs. Frogs use their lungs when they are active and cannot get enough oxygen from cutaneous respiration.
