Alveoli is where gas exchange occurs.
Alveoli- these are the small sac-like structures where gas exchange occurs with the blood. Its creates an ideal site for gas exchange between the air in the lungs and the blood in the capillaries.
By opening and closing the stomata on the underside of the leaves.
The process that occurs during the exchange of gases at the air sacs, or alveoli, is called diffusion. Oxygen from the inhaled air moves across the thin alveolar walls into the bloodstream, where it binds to hemoglobin in red blood cells. Simultaneously, carbon dioxide from the blood diffuses into the alveoli to be exhaled. This gas exchange is essential for maintaining proper oxygen and carbon dioxide levels in the body.
External Respiration is where gasses are absorbed into the blood through the alveolar capillary beds. Internal respiration is where the gasses are transferred into the cells from the blood.
The gas exchange that occurs between the capillaries and oxygen-starved tissues is specifically known as "internal respiration." During this process, oxygen is delivered from the blood in the capillaries to the tissues, while carbon dioxide produced by the tissues is absorbed into the blood. This exchange is crucial for cellular metabolism and maintaining homeostasis within the body.
Alveoli are tiny sacs in the lungs where the exchange of oxygen and carbon dioxide occurs during the process of respiration. They are surrounded by a network of blood vessels, allowing for efficient gas exchange to support bodily functions.
The gas occurs by simple diffusion through the cells.
Gas exchange in fungi occurs predominantly during respiration, which takes place continuously as fungi grow and metabolize. This process involves the uptake of oxygen and release of carbon dioxide and other gases through the fungal cell membrane. Fungi do not have specialized respiratory organs, so gas exchange occurs through diffusion across their cell walls.
