Document Summary

Function is to provide the body with oxygen and to dispose carbon dioxide, an exchange that also regulates the acidity of the body fluids. The 4 process that plays a part in respiration: Ventilation bringing oxygen rich air into the lungs and moving air laden with carbon dioxide out of lungs. Exchange of oxygen and carbon dioxide between the lungs and the blood. Oxygen moves from the lungs into the blood. Carbon dioxide moves from blood into the lungs. Transport of oxygen from the lungs to the cells and of carbon dioxide from the cells to the lungs. Exchange of oxygen and carbon dioxide between blood and tissue cells. Oxygen moves from blood to cells, where its used in cellular respiration to make atp and co2. Co2 made by the cells moves into the blood. Nose help clear particles from air that moves through its passage. Hairs inside the nose filter out the largest particle.
