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
The exchange surfaces are moist.
gaseous exchange
they aren't endangered.
gas exchange occurs between the thin walls of the alveoli and the thin walls of the capillaries
gas exchange occurs between pulmonary capillaries and the alveoli in the lungs.
worms carry out gas exchange by absorbing air through their skin
The actual sites of gas exchange within the lungs are the alvioli.
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.
