Gas exchange and transport A&P

Overview of Gas Exchange and the Respiratory System

• Introduction to gas exchange across membranes
  • Simplification of complex concepts for better understanding
  • Omission of Bohr and Haldane effects for clarity

Respiratory System Structure and Function

• Basic structure covered: Upper respiratory tract and lungs

• Overview of ventilation: Process of bringing air into the body

  • Understanding pressures involved:
  • Atmospheric pressure
  • Alveolar pressure

• Distinction between internal and external environments:

  • Air in lungs is part of the external environment until it crosses the respiratory membrane.
