,College 1: The respiratory system
Breathing → body needs oxygen, CO2 must be removed

Respiration:
• Perfusion: blood flow through the lungs
• Ventilation: movement of air between atmosphere and lungs
• Diffusion: transfer of gasses between lungs and blood




Figure 1, structures of the respiratory system.

Conduction airways:
• Warming
• Filtering
• Moisturizing

Anatomy:
• Trachea
• Oesophagus lies behind the trachea
• Right lung → 3 lobes
• Left lung → 2 lobes, with space for the heart next to the lung
• Bronchus → bronchiole → alveolus (lung vesicle)
