Question

Short notes on:direct And indirect respiration.

Answer 1

Answer:

Direct respiration is defined as the process in which the exchange of gases between the body cells and oxygen takes place directly and for the transportation of gases, blood is not required. This gases exchange takes place by the diffusion process and this type of respiration is commonly observed in unicellular organisms.

On the other hand, indirect respiration is defined as the process where there occurs no direct contact between the body cells. It occurs mainly in the more complex type of animals. They are comprised of important organs such as lungs, gills that help in carrying out the respiration process. here, blood is medium by which these gases are transferred, so it is known as the Indirect respiration.

Answer 2

Difference between direct and indirect respiration

Explanation:

• Direct Respiration- there's an immediate exchange of gases between the carbon-di-oxide of body cells and atomic number 8 of water and there's no blood is required for the transport of gases. The exchange of gases happens on the principle of diffusion. it's found in animate thing organisms like aerobic microorganism or protists e.g. rhizopodan or metazoans like sponges, coelenterates (e.g.Hydra)
• Indirect Respiration-In this kind of respiration there's no direct contact between the body cells and also the close air of water supply of atomic number 8 is thought as a metabolic process medium. this kind is found in a very larger or complicated style of animals. These organisms have some specialised organs like gills (most of the crustaceans molluscs), lungs ( some amphibians, snails, all reptiles, birds or mammals).In this, the transportation of atomic number 8 or carbon-di-oxide between the metabolic process organs or the body cells is caused by the blood of the vascular system. So, it's known as Indirect respiration
