Study Notes
Respiratory System
- Foreign bodies or aspirated material are more likely to get stuck in, or pass through, the right mainstream bronchus due to its sharper angle.
Ventilation
- Ventilation is the inspiration and expiration of air due to the lungs filling and emptying via the movement of the diaphragm and intercostal muscles.
Respiration
- Respiration is the exchange of oxygen and carbon dioxide.
- There are two types of respiration: external and internal.
- External respiration occurs between the outside air and the blood.
- Internal respiration occurs between the blood and the cells.
Pathway of Blood Flow
- The pathway of blood flow for respiration is: right heart -> pulmonary arteries -> alveolar capillaries -> pulmonary veins -> left heart -> body.
Pulmonary Arteries and Veins
- Pulmonary arteries carry deoxygenated blood.
- Pulmonary veins carry oxygenated blood, which is the opposite of the arteries and veins in the rest of the body.
Nerve Signals
- All nerve signals to the diaphragm go through the phrenic nerve.
- The phrenic nerve comes from the nerve roots of the cervical spine.
