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
