Gaseous Exchange in Earthworm
Earthworm has a segmented cylindrical body covered by a thin cuticle below which is the epidermis. This skin is always kept very moist by the secretion of mucus from the epidermis and body fluids from the excretory pores. It always lives in moist soil especially during the day. This prevents their ..

Frogs respire through skin as well as the lungs. The oxygen rich air enters the skin or lungs. From here the blood picks up the oxygen and transports it to the tissues of various organs. From the tissues the blood picks up carbon dioxide and transports it back to the skin or the lungs from where it..

Gaseous Exchange in Plants
In lower plants (and also protozoans) exchange of gases takes place through the general body surface as they are not highly modified or specialised. Also, the body surface allows the diffusion of gases. In higher plants the exchange of gases takes place through stomat..
Gaseous Exchange in Fish
The region between the buccal cavity (mouth) and the oesophagus is called the pharynx. In the pharyngeal region, the wall on either side shows slits which open to the exterior. These slits are called the gill slits. The gill slits are separated by a tissue called the gill arch or the branchia..
Gaseous Exchange in Grasshopper
The respiratory system in insects is called the tracheal system. It involves the diffusion of oxygen directly from the atmosphere into the air-filled tubes. Thus, the diffusion is through air and hence, is more efficient than the diffusion through water (300,000 times more) or tissues (1,000,..
