What do you mean by internal respiration?
Medical Definition of internal respiration : the exchange of gases (as oxygen and carbon dioxide) between the cells of the body and the blood by way of the fluid bathing the cells — compare external respiration.
What do you understand by internal and external respiration?
External respiration, also known as breathing, involves both bringing air into the lungs (inhalation) and releasing air to the atmosphere (exhalation). During internal respiration, oxygen and carbon dioxide are exchanged between the cells and blood vessels.
What is internal respiration Class 7?
Cellular respiration or internal respiration: This is the process of breakdown of food in the presence of oxygen into carbon dioxide and water to release energy.
Why is it called internal respiration?
Gas exchange in the metabolizing tissues is referred to as internal respiration. Compared with external respiration, the gases now move in opposite directions. That is, oxygen diffuses out of the blood into the tissues, and carbon dioxide diffuses out of the tissues into the blood.
What is the difference between external and internal respiration?
Internal and external respiration are two types of respiration processes in which internal respiration occurs inside the cells while external respiration occurs between the body and the external environment. Internal respiration is the process of breaking down of glucose at the cellular level to produce energy.
What happens during internal respiration?
Internal respiration occurs within cells of the body and involves all body cells, not just cells of the lungs. It uses oxygen to break down molecules in order to release energy in the form of adenosine triphosphate (ATP).
What is the process of internal respiration?
Internal Respiration Definition. Internal respiration is the process of diffusing oxygen from the blood, into the interstitial fluid and into the cells. Waste and carbon dioxide are also diffused the other direction, from the cells to the blood.
What is the definition of internal respiration?
Medical Definition of internal respiration. : the exchange of gases (as oxygen and carbon dioxide) between the cells of the body and the blood by way of the fluid bathing the cells — compare external respiration.
