What is gaseas exchange?

Answer 1

Gaseous exchange is the biological process through which organisms exchange gases, primarily oxygen and carbon dioxide, with their environment. In humans and many animals, this occurs in the lungs where oxygen is inhaled into the alveoli and diffuses into the bloodstream, while carbon dioxide is expelled from the blood into the alveoli to be exhaled. In plants, gaseous exchange occurs through small openings called stomata, where carbon dioxide enters for photosynthesis and oxygen is released as a byproduct. This process is essential for maintaining cellular respiration and overall metabolic functions.
