What is indirect respiration?

indirect respiration is a gaseous exchange that involves two phases: a. external respiration - exchange of gases between environment and tissues. b. internal respiration - exchange of gases between the tissues and body cells juiysiey ",


External respiration involves?

External respiration is the exchange of gases between each lung and blood. It involves inhaling gases from the organisms external environment, and then exhaling the gases back out.


Gas exchange is also known as?

Respiration is a process of gas exchange. Respiration is necessary to supply cells with oxygen for metabolism and to remove the waste by product carbon dioxide.


What does internal and external respiration mean?

External respiration refers to the act of mechanically pulling air into the lungs via breathing. Internal respiration is the exchange of gasses from blood to tissue and vice versa.


What is the difference between external respiration and tissue respiration?

External respiration is gas exchange in the lungs. Tissue respiration is the chemical reactions in our cells which produce energy. The most usual one is aerobic respiration: glucose + oxygen --> carbon dioxide and water.


Is the exchange of gases within the cells of the body known as internal respiration?

No. The exchange of gases between the blood and tissue cells is called internal respiration. External respiration refers to the exchange of gases between the blood and the air inside of the alveoli of the lungs.


External respiration refers to the exchange of oxygen and carbon dioxide between?

Alveoli and bloodstream


Where is respiration in an animal cell?

Respiration is the process by which oxygen is delivered from the external environment to the cells for cellular exchange. Most occurs in the lungs of the animal


What does internal and external cells mean?

External respiration refers to the act of mechanically pulling air into the lungs via breathing. Internal respiration is the exchange of gasses from blood to tissue and vice versa.


What is external respiration and internal respiration?

External respiration is to breathe and facilitate gas exchange in the lungs or an analogous body cavity, depending on the organisms anatomy. Cellular respiration is the process of oxidative phosphorylation, where ATP energy is generated from biomolecules by the cell. In aerobes, the process involves a series of electron steps and oxygen is the terminal electron acceptor


Define external respiration?

External Respiration-the process of first inhaling oxygen (02) and then proceeding to EXHALING the inhaled oxygen in the lungs in the form of carbon dioxide (C02) into the environment, then repeating the process all over again. (the entire process is commonly known as cellular respiration.)


What is the difference between external ventilation and internal ventilation?

External respiration, the process by which gases are exchanged between the atmosphere and the pulmonary loop of circulationWhereas,Internal respiration: the is the gaseous exchange between the blood and tissue ( and also cells)
