Final answer:
The process where blood circulates oxygen from the lungs to body tissues is called internal respiration, involving gas exchange at the tissue level to provide oxygen for cellular metabolism and remove carbon dioxide.
Step-by-step explanation:
The process by which blood circulates oxygen from the lungs to the body's tissues is an example of internal respiration. This is the phase of respiration where gas exchange occurs at the level of body tissues. Oxygen, carried by hemoglobin within erythrocytes, dissociates from the hemoglobin and diffuses from the blood, crossing the interstitial space, into the body cells, where it is needed for cellular metabolism. Conversely, carbon dioxide, a metabolic waste produced by cells, diffuses from the tissues back into the blood to be transported to the lungs and expelled from the body. Internal respiration is critical in maintaining homeostasis by ensuring the delivery of oxygen to the cells for energy production and removal of carbon dioxide to regulate blood pH.
The process by which blood circulates oxygen from the lungs to the body's tissues is an example of internal respiration. Internal respiration refers to gas exchange that occurs at the level of body tissues. It involves the delivery of oxygen to the cells and the removal of carbon dioxide from the cells by the circulatory system.
