Understanding Lung Function A Microscopic Look at Oxygen and Carbon Dioxide Exchange in Alveoli #353097611
Description
This microscopic image reveals the intricate process of gas exchange within the lungs. Alveoli, tiny air sacs, are the primary sites where oxygen from inhaled air diffuses into the bloodstream, while carbon dioxide, a waste product of cellular respiration, diffuses out. The thin walls of the alveoli and surrounding capillaries facilitate this vital exchange, allowing oxygen to reach the body
