Respiratory system anatomy — key structures?
Nasal cavity, pharynx, larynx, trachea, bronchi, alveoli.
Nasal Cavity — function?
Filters, warms, moistens incoming air.
Pulmonary capacities — example?
Vital capacity, total lung capacity.
Pharynx — role?
Passageway for air and food.
Mechanism of respiration — process?
Ventilation, gas diffusion, and gas exchange.
Larynx — also known as?
Voice box; involved in phonation.
Trachea — lining?
Ciliated mucosa to trap debris.
Alveoli — function?
Gas exchange with blood.
Gas transport — occurs where?
In blood via hemoglobin.
Respiration — process?
Gas exchange between environment and tissues.
