The site of gas exchange in lungs is alveolar sac...it is a small sac like structure which contracts n expands when gases are exchanged..it is connected to bronchiole..which in turn connected to bronchus..this whole structure is like an inverted tree
Gas exchange takes place inside the lungs in the alveoli. The alveoli are a "grape like" structure at the very end of the respiratory tract. The alveoli are composed of a very thin membrane that separates the blood vessels from the gas chambers. The thin membrane allows diffusion of oxygen into the blood stream and diffusion of carbon dioxide (CO2) out of the blood stream. Once the CO2 has diffused into the alveoli, it is exhaled.
In the capillaries
the organ that is involved in gas exchange is the lung. the specific lung structure that is the site for gas exchange is the alveolus which is part of the alveoli, which is found in the lung.
They are the alveoli.
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.
The site of respiration is the cells, more specifically, the mitochondria
Lungs do not pump blood. They are the site of gas exchange between capillaries and alveoli.
There are many capillaries in the lungs. These small blood vessels are the site of gas exchange in the alveoli.
Capillaries connect small arteries to small veins. Capillaries are the site of gas exchange.
Alveoli are site of gas exchange. Actual diffusion of gases occurs at interstitial space between capillaries and alveolar cells.
Capillaries are the tiniest blood vessels. They are the site of gas exchange and connect veins and arteries.
