My name is Tammy van Druten and I am currently a 3rd year occupational therapy student at UCT. Last year, I thoroughly enjoyed HUB2015W and compiled concise, visually-pleasing notes to help me study. These notes should be used in conjunction with the lecturer's PowerPoints.

• Comprised of:
→ Respiratory tract = the pathway via which air gets to the lungs

TERMINOLOGY
• VENTILATION
→ Movement of air into and out of lungs
→ Breathing
• RESPIRATION
→ Exchange of O2 and CO2 across membranes
→ External Respiration: Gaseous exchange between the lungs and the blood
→ Internal Respiration: Gaseous exchange between the blood and the tissues of the body
