NCCQ anatomy and physiology revision- the respiratory system |
UPDATED Questions with 100% Verified Answers
Question:
What is the process of taking oxygen from the air and
transporting it to individual body cells, and the subsequent

air?
Answer:
Respiration
Question:
What are the functions of the respiratory system?
Answer:
Provides the route by which oxygen enters the body and by which carbon dioxide is
excreted. This system also plays a role in regulating body temperature

Question:
How is breathing accomplished?
Answer:
By the diaphragm and the muscles of the chest wall
Question:
What is the trachea?
Answer:

Answer:
So that air reaches all segments of the lungs
Question:
What is a bronchiole?
