Respiration in insects
An insect body is covered with air holes called as spiracles.
*Air enters through these air holes on the body and finally reaches the trachea.
*Trachea are a network of fine air tubes extending through out the body.
*Trachea help in circulating the oxygen throughout the body.
*The oxygen in the air diffuses into the tissues and is ultimately absorbed by the cells.
*The carbon dioxide released by the cells is carried by the trachea and given out through the spiracles.
Respiration in frogs
Frog is an amphibian having two lives, one in water and one on land.
*Frogs are the only organisms which exhibit cutaneous, branchial and pulmonary respiration in during different stages of their life cycle.
*Adult frogs can breathe through their skin. Skin is moist and slimy helping the animal to respire through skin under water as well as on land. This is termed to be cutaneous respiration.
*Adult frogs while on land respire through lungs. Lungs are the respiratory organs which help in exchange of gases. This is termed to be pulmonary respiration.
*Tadpoles, the larval stages of frog live in water. They respire through their gills as they do not possess well developed lungs. This is termed to be branchial respiration.
