Study Notes
Gas Exchange in the Respiratory System
- The main function of gas exchange occurs in the alveoli, the tiny air sacs located at the end of the bronchioles.
Ventilating Mechanism of the Lungs
- The ventilating mechanism involves the diaphragm and intercostal muscles, which contract and relax to facilitate breathing.
Conducting Portion of the Respiratory System
- The conducting portion includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, which transport air into and out of the lungs.
Cellular Sites of Gas Exchange
- The cellular sites of gas exchange, where O2 and CO2 are exchanged between inspired air and the blood, occur in the alveolar-capillary membrane.
Linking Sites of Gas Exchange with the External Environment
- The trachea, bronchi, and bronchioles link the sites of gas exchange with the external environment, allowing air to enter and exit the lungs.
