Respiratory Physiology

• What is the first step in the oxygenation of blood process?

  Ventilation
• What does ventilation refer to in respiratory physiology?

  Process of air moving in and out of the lungs
• What is the second step in the oxygenation of blood process?

  Perfusion
• What is the role of perfusion in the oxygenation of blood?

  Pump oxygenated blood throughout the body
• What is the third step in the oxygenation of blood process?

  Diffusion
• What occurs during diffusion in the context of respiratory physiology?

  Deliveries oxygen where it needs to go
• What is atelectasis?

  Collapse of the alveoli
• What are the three steps in the oxygenation of blood?

  1. Ventilation: air moves in and out of lungs
  2. Perfusion: pump oxygenated blood throughout the body
  3. Diffusion: delivers oxygen at the alveoli-capillary level
