gaseous exchange
1 answer
Gaseous exchange refers to the process of exchanging gases, primarily oxygen and carbon dioxide, between an organism and its environment. In animals, gaseous exchange occurs in the lungs, where oxygen from the air is diffused into the bloodstream and carbon dioxide is diffused out of the bloodstream into the lungs to be exhaled. In plants, gaseous exchange occurs through tiny pores called stomata, where carbon dioxide is taken in for photosynthesis and oxygen is released as a waste product. Gaseous exchange is essential for the survival of both animals and plants, as it allows for the necessary exchange of gases required for respiration and energy production.
