Question 5 of 5
How much air does an adult inhale in an average breath?
Correct Answer: A
Rationale: An adult typically inhales around 500 mL of air in an average breath. This volume is known as tidal volume, representing the amount of air inspired or expired during normal breathing. Tidal volume plays a crucial role in efficient gas exchange in the lungs and maintaining adequate oxygen levels in the body. It is essential for proper respiratory function and ensuring the body receives the necessary oxygen for cellular respiration and overall metabolism.
