Study Notes
Functions of the Respiratory System
- Functions include gas exchange, regulation of blood pH, and olfaction (sense of smell).
- A function that is NOT typically associated with the respiratory system is digestion or nutrient absorption.
Microscopic Air Sacs
- Microscopic air sacs in the lungs of mammals and reptiles are called alveoli.
- Alveoli are crucial for facilitating gas exchange between air and blood.
Organ for Gas Exchange
- The organ responsible for bringing air into close contact with blood is the alveoli, located in the lungs.
- Capillaries surround the alveoli, allowing oxygen and carbon dioxide to diffuse rapidly between air and blood.
Largest Airway
- The trachea is the largest airway in the respiratory system.
- It branches into bronchi, leading into smaller airways and eventually the alveoli.
Internal Respiratory Surfaces
- In mammals and reptiles, the respiratory surface is internalized as linings of the lungs.
- This adaptation allows for more efficient gas exchange in terrestrial environments.
