Study Notes
Respiratory System Functions and Key Structures
- Trachea facilitates air conduction from the nose/mouth to the lungs and aids in gas exchange
- Trachea lined with cilia and mucus for protection and removal of contaminants
- Trachea's cartilage rings provide mechanical support and prevent collapse during breathing
- Trachea initiates cough reflex to expel irritants from the respiratory tract
- Larynx, or voice box, produces sound through vocal cords and protects the airway during swallowing
- Surfactant, produced by type 2 alveolar cells, reduces surface tension in alveoli to aid breathing
- Insufficient surfactant in premature babies can lead to Respiratory Distress Syndrome
- Bronchi are larger and bronchioles are smaller, allowing for efficient air distribution in the lungs
- Circulatory system works closely with the respiratory system to deliver oxygen throughout the body
- Increased carbon dioxide in blood leads to acidity, while decreased carbon dioxide leads to alkalinity
- Nasal cavity warms, humidifies, and filters the air before it reaches the respiratory passages
- The nasal cavity is responsible for warming, humidifying, and filtering the air before it reaches the lungs
