Difference between External and Internal Respiration | Zoology

The upcoming discussion will update you about the difference between external and internal respiration in animals. Difference # External Respiration: 1. It is a physical pro­cess in which oxygen (O2) is absorbed and carbon dioxide (CO2) is given out. 2. Enzymes do not play any role in the process. 3. Restricted to respi­ratory organs only. 4. Respiratory struc­tures are body [...]

Exchange of Gases in Respiration | Zoology

In this article we will discuss about the need for the exchange of gases in respiration. 1. Transport of oxygen in the air or the oxy­gen dissolved in water to organs of respi­ration, gills or lungs. In cases, the body surface functioning as the respiratory or­gan, it is in direct contact with the oxygen in water or air. 2. Diffusion [...]

How Carbon Dioxide and Oxygen is Transported through Blood?

In normal condition an animal body requires enormous amount of oxygen to satisfy the demands of the energy yielding oxidative phosphorylation reactions. Various respiratory pigments serve to carry the necessary oxygen from the atmosphere to different parts of the body. Of the several pig­ments, haemoglobin is the most efficient in transporting respiratory gases. Haemoglobin molecule has high affinity for oxygen [...]
