The site of respiration is the cells, more specifically, the mitochondria
The gas exchange between carbon dioxide and oxygen occurs in the lung, more specifically the alveolus where the thin membrane allows the gas to pass through.
The pulmonary capillaries
internal respiration
alveoli
Blood releases its oxygen into the tissues at the capillary level.
Respiration is a process of gas exchange. Respiration is necessary to supply cells with oxygen for metabolism and to remove the waste by product carbon dioxide.
"alveoli"
They are designed to exchange materials such as the alveoli exchange gases or the capillary walls exchange fluid and nutrients with the intestitial tissues.
When the partial pressure between the alveoli and the blood, or between the blood and the tissues, is different - i.e. when a concentration gradient exists.
The capillary is the smallest of the blood vessels. It is the site of gas exchange between the blood and the tissues.
They can control gas exchange in the tissues. When they are constricted, there is almost complete no gas exchange. The blood just bypasses the tissues.
Capillaries are the smallest blood vessels. They connect arteries and veins. They are the site of gas, waste, and nutrient exchange between the blood and the body tissues.
skin is responsible for gas exchange in frogs, but not in snakes
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.
It is called wrapped tissues
Capillaries are the smallest blood vessels, and they allow for gas exchange in the tissues.
