Gas exchange is a function of respiration not digestion.
Alveoli is where gas exchange occurs.
It lowers the area available for gas exchange, therefore gas exchange doesn't happen as quickly or as much as it should.
Capillary system is where gas exchange occurs
is this effects liver
The exchange surfaces are moist.
gaseous exchange
gas exchange occurs between pulmonary capillaries and the alveoli in the lungs.
gas exchange occurs between the thin walls of the alveoli and the thin walls of the capillaries
worms carry out gas exchange by absorbing air through their skin
The actual sites of gas exchange within the lungs are the alvioli.
Capillaries. Since they are only once endothelial cell thick, they can exchange gas, nutrients, and waste across their membrane. Capillaries in the brain have endothelial cells close together to onyl allow a slecetive exchange of materials, while capillaries in the kidney or liver have gaps between the endothelial cells to allow the exchange of a lot of materials.
