Study Notes
Importance of Oxygen
- Oxygen is essential for organs to function and the body to stay alive
Respiratory System Components
- The respiratory system works with the heart to bring oxygen from air to blood to tissues to organs
- Lungs and chest wall play a crucial role in inspirations and expiration of air
- Respiratory accessory muscles stabilize thoracic cavity and enhance ventilation during high oxygen demand
Division of the Respiratory System
- Upper respiratory tract includes the nasopharynx and oropharynx
- Lower respiratory tract includes the trachea, bronchi, bronchioles, and lungs
Diaphragm Function
- Diaphragm: a muscle at the base of the lungs, pulls air into airways by creating negative pressure in the chest
Physiology of the Respiratory System
- Gas exchange in lungs takes place in lung tissue between alveoli and capillaries
- Gas exchange involves the exchange of carbon dioxide and oxygen
- Lungs are sponge-like, elastic, cone-shaped organs in the chest cavity
Airways and Defense
- Airways have protective mechanisms against viruses and bacteria
Factors Affecting Respiratory Health
- Older patients are at higher risk of complications due to genetics and environment
- Women have greater bronchial hyperreactivity and larger airways, increasing the risk of rapid lung function decline
- Individuals with dark skin usually show lower oxygen saturation
- Assess their sclera and mucous membranes for paleness and cyanosis
