Gas exchange flashcards are a helpful study tool for learning about the process of exchanging gases in the body. Our flashcards feature English words related to gas exchange on one side, and the definitions on the other side. Additionally, the flashcards include audio pronunciations to help reinforce learning. Study with our gas exchange flashcards to improve your understanding of this critical biological process.
Gas exchange is the process by which the body takes in oxygen from the air and eliminates carbon dioxide. This critical function occurs in the lungs, where tiny air sacs called alveoli absorb oxygen and release carbon dioxide during breathing. Good gas exchange is essential for our bodies to function correctly and stay healthy.

quick facts
Gas exchange is the process where oxygen from the air enters the bloodstream and carbon dioxide from the bloodstream exits into the air.
Humans have specialized organs called lungs that help with gas exchange. Fish have gills, while insects have tiny tubes called tracheae.
Plants also undergo gas exchange through tiny openings on their leaves called stomata. They take in carbon dioxide and release oxygen during photosynthesis.
During exercise, our bodies need more oxygen, so we breathe faster and deeper to increase the rate of gas exchange in the lungs.
Gas exchange is essential for all living organisms to get the oxygen they need for cellular respiration, which produces energy for their bodies to function.
