Document Summary
Purpose of respiration: provides oxygen (o2) and removes carbon dioxide (co2), hydrogen ions (h+), and water (h2o) Transfer of gases: transported in red blood cells and plasma, o2 binds on hemoglobin, travels into blood stream and then oxygen defuses out and carbon dioxide diffuses in. Moves air in and out of the lungs: external respiration exchange of gases between the air and blood, gas transport. Gases carried to organs, tissues, and muscles in the blood. Measuring lung volume: lung volumes are measured with a spirometry, want to make sure someone gets enough oxygen based on lung size, tidal volume: volume of air inhaled & exhaled during a normal breath. Inspiratory capacity: max volume of air that can be inhaled in one breath. Vo2 max: max amount of oxygen that can be consumed and used by the body, peak level of o2 used is the vo2 max and provides an indication of fitness level.
