clearly explain the difference between external and internal respiration

Internal respiration, being a chemical process, is an involuntary event, while external respiration is voluntary (holding one’s breath) and involuntary as it is controlled by the brain. Internal respiration involves three stages: glycolysis, Krebs cycle and oxidative phosphorylation; this is not the case for external respiration. Dr. Rae Osborn. Gases move between cells in external respiration. very nice explaination……mastttt Consider the difference between internal respiration and external respiration and explain why lung capacity may not have a great effect on length of time you can hold your breath. It is the process called cellular respiration. External respiration occurs in the alveoli of the lungs. 2.Stöppler, Melissa Conrad. External respiration involves breathing, while internal respiration does not. It takes place prior to internal respiration. Two things happen during the gas exchange; oxygen goes into blood and carbon dioxide diffuses out into lungs. Internal respiration occurs within cells of the body and involves all body cells, not just cells of the lungs. Internal respiration involves protons eventually combining with oxygen to form water while in external respiration oxygen combines with hemoglobin to form oxyhemoglobin. pH is lower and temp is higher. External respiration is basically the transfer of gas between respiratory organs such as lungs and the outer environment. Breathing:. Very few organisms can continue to undergo cellular respiration in the absence of oxygen. It occurs in the mitochondria and it involves taking glucose (blood sugar) in, and oxidizing it to carbon dioxide and water. However, animals do not always voluntarily breathe, but it is an ever happening involuntary process as the centres of the brainstem automatically regulate the external respiration. External respiration is the mechanism of how oxygen physically enters the body and is moved around, while internal respiration is only a process of chemical reactions which involves oxygen as a driving force. 1.“Cellular Respiration:” Chapter 3 – Proteins. External respiration provides oxygen to internal respiration as well as it removes carbon dioxide that produced by the internal respiration. Difference Between Breathing and Respiration April 9, 2019 by Rachna C 1 Comment Breathing is the biophysical process which involves the inhaling and exhaling of air through lungs, whereas respiration is the biochemical process which involves in generating the energy by breaking down the glucose which is further used by cells in various function. Why do we do the things we do? @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } 2. The internal and and external respiration are the two types of respiration in the body. Oxygen that is inhaled diffuses from the alveoli into the blood of capillaries. External respiration involves oxygen first entering the ventilatory structures such as lungs or gills; this is not the case with internal respiration. Compare the Difference Between Similar Terms. Internal respiration is the process of breaking down of glucose at the cellular level to produce energy. Side by Side Comparison – Internal vs External Respiration in Tabular Form External respiration involves breathing, while internal respiration does not. When you have a bad head cold, you breathe through your mouth. External occurs at alveoli. She holds Honors Bachelor of Science degrees in Zoology and Entomology, and Masters of Science in Entomology from the University of Natal in South Africa. External respiration also involves gas exchange, the exchange of oxygen and carbon dioxide between body cells and blood cells. - refers to the legitimacy or authenticity of the document that a researcher uses in a historical study. There are two types: aerobic respiration which requires oxygen and anaerobic respiration which does not require oxygen. It is a vital process for life as it supplies oxygen to extract energy from food via internal or cellular respiration. Internal respiration can sometimes occur without oxygen, this is not the case with external respiration. - Yes with the vital capacity you can hold your breath longer because you are used to that heavy breathing. Water is formed when protons combine with oxygen at the end of the electron transport chain. External respiration is a voluntary action, which the animal can control. Consider the difference between internal respiration and external respiration and explain why lung capacity may not have a great effect on length of time you can hold your breath. Glycolysis occurs in the cytoplasm of the cells while Krebs cycle and electron transport chain take place inside the mitochondria. Trace the route of air from the external nares to the alveolus.

Oxygen provides a force to drive the transport of electrons down the chain. March 8, 2018 < http://www.differencebetween.net/science/health/difference-between-external-respiration-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 … External respiration consists of two stages: The first stage involves ventilation or breathing, which is the intake of oxygen into the body and expulsion of carbon dioxide out of the body. In mammals, there are two types of respirations existent; namely, internal respiration and external respiration. Internal respiration is often also called cellular respiration since it occurs within the cell. Internal Respiration: Oxygen diffuses out from the blood into tissue … 6.
