What are 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 the difference between internal and internal respiration?

The main difference between internal respiration and external respiration is that internal respiration refers to the gas exchange across the respiratory membrane in the metabolizing tissues whereas external respiration refers to the gas exchange across the respiratory membrane of lungs.

What are the two types of internal respiration?

Internal respiration involves gas exchange between the blood and body cells. Cellular respiration involves the conversion of food to energy. Aerobic respiration is a cellular respiration that requires oxygen while anaerobic respiration does not.

What is the difference between external and internal respiration class 7th?

Internal respiration is an active process, as it requires energy. It uses oxygen to produce energy and produces carbon dioxide and water as waste product. External respiration: It is the process of taking oxygen into and expelling carbon-dioxide from the body.

What are the two types of external respiration?

External respiration also involves gas exchange, the exchange of oxygen and carbon dioxide between body cells and blood cells. Internal respiration is the respiration that occurs within a cell. There are two types: aerobic respiration which requires oxygen and anaerobic respiration which does not require oxygen.

What is external respiration?

Definition of external respiration : exchange of gases between the external environment and a distributing system of the animal body (such as the lungs of higher vertebrates or the tracheal tubes of insects) or between the alveoli of the lungs and the blood — compare internal respiration.

What is external respiration and internal respiration Class 10?

∙ External respiration: It takes place in the alveoli in lungs. Taking in of O2 and giving out of CO2 is termed as external respiration or breathing or ventilation. It is a physical process. ∙ Internal respiration: Intake of O2 by the body cells and production of CO2 and ATP is called internal or cellular respiration.

What is internal breathing?

Definition of internal respiration : an exchange of gases between the cells of the body and the blood by way of the fluid bathing the cells — compare external respiration.

What is internal ventilation?

This includes during – Internal respiration – this is the movement in the internal tissues between cells and capillaries, and – External respiration – when gas is exchanged between the alveoli and lung capillaries. Perfusion refers to the blood flow to tissues and organs.

What is an example of external respiration?

External respiration, commonly known as breathing, is the exchange of oxygen and carbon dioxide between an animal and its environment. Most animals use specialized organs or organ systems, such as lungs, trachea, or gills, for external respiration.

What is meant 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.
