Study Notes
Respiratory System
- The main site of gas exchange in the lungs is the alveoli, where oxygen is absorbed into the blood and carbon dioxide is removed.
Diaphragm's Role
- The diaphragm is a dome-shaped muscle that separates the chest cavity from the abdominal cavity and plays a crucial role in breathing by contracting and relaxing to expand and deflate the lungs.
Respiratory Disorders
- Emphysema, chronic bronchitis, and asthma are all respiratory disorders, but arthritis is NOT a respiratory disorder; it is a joint disorder.
