Question

discribe the buccal respiration in frog ​

Answer 1

Answer:

The respiration which takes place through buccopharyngeal cavity, it is called buccopharyngeal respiration.

The buccal cavity consists of moist mucous membrane and richly supplied with blood capillaries.It absorbs oxygen through diffusion or simply by contraction or expansion of sternohyals and petrohyals muscles. Oxygen dissolves in moist mucous of the cavity and diffuses into the blood capillaries. Similarly, CO2 diffuses out into the cavity and passes out through nares during expiration.

[The lungs donot take part in this respiration.

Sternohyal muscle lies below the mouth cavity. It connects hyoid and sternum when it contracts, the mouth cavity is lowered downwards. The petrohyal muscle lie outside the mouth cavity and the upper and lower ends connect squamosal bone and hyoid respectively. When it contracts, the mouth cavity is pushed upwards.]
