Study Notes
Respiratory and Circulatory Interaction
- Air enters lungs, begins the process of oxygenation and nutrient transport.
- Oxygen travels from lungs to the left side of the heart, where it is pumped into the bloodstream.
Heart Function and Blood Circulation
- The heart's primary role is to pump blood throughout the body, ensuring delivery of nutrients and oxygen.
- Blood serves as a transport medium for essential components: nutrients, oxygen, and other chemicals.
Cellular Energy Production
- Oxygen is utilized by cells to process nutrients, resulting in energy release.
- Carbon dioxide is a byproduct of energy production within cells.
Carbon Dioxide Elimination
- Blood carries carbon dioxide to the right side of the heart for transportation to the lungs.
- Exhalation from the lungs expels carbon dioxide, removing waste from the body.
