Internal respiration is the transfer of gas between the blood and cells. External respiration also known as breathing refers to a process of inhaling oxygen from the air into the lungs and expelling carbon dioxide from the lungs to the air
Gas exchange in the lungs is referred to as external respiration as one side of the respiratory membrane-that is, the alveolar air-is actually outside of the body. As blood flows through the pulmonary capillaries, oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar gas. Internal and External Respiration. There is a big difference between external and internal respiration. External respiration is basically the transfer of gas between respiratory organs such as lungs and the outer environment. It takes place prior to internal respiration. Internal respiration is the transfer of gas between the blood and cells. External respiration also known as breathing refers to a process of inhaling oxygen from the air into the lungs and expelling carbon dioxide from the lungs to the air. Exchange of gases both in and out of the blood occurs simultaneously. External respiration or breathing is a process of inhaling the air into the lungs and expelling the air that contains more carbon-di-oxide from the lungs to the outer environment. Exchange of gases in and out of the blood also takes place simultaneously. External respiration is the process of taking oxygen into and expelling carbon dioxide from the body. External respiration is essential for life as it supplies oxygen to extract energy from food via internal or cellular respiration. Additionally, it removes carbon dioxide, which is a waste product of This page is about internal respiration, which is the processes by which the gases in the air that has already been drawn. by external respiration are exchanged with gases in the blood/tissues so that carbon dioxide (CO 2) is removed from the blood and replaced with oxygen (O 2).
