Study Notes
Ventilation Drivers
- Ventilation is driven by the need to take in oxygen (O2) and expel carbon dioxide (CO2) from the body.
Gas Exchange
- Gas exchange occurs at the tissue level in the capillaries, where oxygen and nutrients diffuse into cells and carbon dioxide and waste products diffuse out.
Demand for Ventilation
- The demand for ventilation is determined by the body's metabolic rate, as a higher metabolic rate requires more oxygen and produces more carbon dioxide.
Oxygen and Carbon Dioxide Loading/Unloading
- The rate of loading and unloading of oxygen and carbon dioxide is influenced by factors such as exercise, altitude, and respiratory and cardiovascular diseases.
Right Heart Function
- The primary function of the right heart in gas transport is to pump oxygen-depleted blood from the body to the lungs, where it can be re-oxygenated.
