Respiratory System
Guided Notes
3 key concepts
- 1
The respiratory system facilitates gas exchange, taking in oxygen for cellular respiration and expelling carbon dioxide as a waste product.
- 2
Inhaled air travels through the nasal cavity, pharynx, larynx, trachea, and bronchi before reaching the alveoli, where gas exchange occurs with capillaries.
- 3
The nervous system regulates breathing rate and depth by monitoring pH levels in the blood, which are affected by carbon dioxide concentration.
