WebThe actual gas exchange occurs in a structure called the alveoli, these are small grape like structures that allow efficient gas exchange to occur. Alveoli are surrounded by a dense network of capillaries, one cell thick blood vessels, … WebGases move freely, but gas particles are constantly hitting the walls of their vessel, thereby producing gas pressure. Air is a mixture of gases, primarily nitrogen (N 2; 78.6 percent), oxygen (O 2; 20.9 percent), water vapor (H 2 O; 0.5 percent), and carbon dioxide (CO 2; 0.04 percent). Each gas component of that mixture exerts a pressure.
