I have to describe how the respiratory system normally works for an assignment. Think, "normal respiration". Although I should know this material, I am having difficulty explaining it. So i am looking for the steps for that takes place during normal respiration.
Ex:
1. Air enters through the nose and mouth, through the upper airway to the lungs.
2. At the same time, Deoxygenated blood is carried from the heart to the lungs
3. Gas exchange takes place at capilaries
4.. Oxygenated blood is carried fro lungs to the heart.
