Question

explain the process of respiration in terrestrial organisms

Answer 1

Certain terrestrial animals, such as earthworms and amphibians, can breathe through their skins, but amphibians have simple lungs as well. All reptiles, mammals and birds breathe using lungs; in birds there is also a system of air sacs and air spaces within the bones that make breathing more efficient.

Answer 2

respiration is the process of releasing energy from food... the air is taking in the body by the nostrils then it passes through the nasal cavity than trachea than bronchi than it finally goes into alveioli. when we breathe in then the muscles attached to the rib and the diaphragm contract due to which the chest cavity expands and the volume inside the chest cavity increases due to which pressure inside it decreases and the air from outside russes into the alveoli where the exchange of gases takes place the alveoli is surrounded by blood vessels called capillaries which carry blood into them. the oxygen from the alveoli difuses into the blood which is Transporter to the all part of the body by hemoglobin.since the blood passes through tissues the oxygen diffuses into the cells where it react with food and produces energy and and carbon dioxide is produce as a waste product during the reaction of respiration. this carbon dioxide diffuses to the blood and goes to the lungs and diffuses to alveoli and than while breathing out it is removed from our body.....
