Why is the continual exchange of gases in both external and internal respiration essential for survival?
oxygen fuels the brain.....
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 from respiration and breathing?
Internal Respiration: Is changing food (glucose) into energy. External Respiration: Is breathing in and out.
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 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)
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.
What are the cellular respiratory processes that lungs perform?

What are the 2 main types of muscles in respiration and how do they work?
muscle of respiration: diaphragm, external intercostrals and internal intercostrals - internal intercostral- pull ribs up and out - external intercostrals- pull ribs down and in - diaphragm-contracts in preparation for sneezing,coughing,crying,laughing and weight lifting.
When air enters the alveoli of human lungs is the oxygen it contains truly in the internal environment of the human?
No. This is an common misconceptiion. Respiration is considered external if it occurs in the lungs. When it occurs in body tissues it is considered internal respiration.
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

Why is external respiration vital to cellular respiration?
