Study Notes
Gas Exchange
- Gas exchange occurs in the alveoli in mammals and reptiles; in birds, it occurs in atria.
- Alveoli are small air sacs that provide a large surface area for efficient gas exchange.
Trachea and Bronchi
- The trachea divides into two main bronchi that lead to each lung.
- Bronchi further branch into smaller bronchioles within the lungs.
Respiratory System Exclusivity
- The respiratory system is a feature exclusive to animals and is absent in plants.
- Plants utilize a different method for gas exchange, primarily through stomata.
Respiratory Surface in Land Animals
- In land animals, the respiratory surface is internalized, typically forming the linings of the lungs.
- This internalization protects the respiratory surfaces from external environmental conditions.
Size and Respiratory Anatomy
- The size of an organism does not influence the basic anatomy and physiology of the respiratory system.
- Regardless of an animal's size, the fundamental structures for respiration remain consistent across species.
