Question

Check valves allow air/gas to flow properly in both directions (True/False)

a) True
b) False

Answer 1

Check valves do not allow air/gas to flow properly in both directions.

Step-by-step explanation:

The statement that check valves allow air/gas to flow properly in both directions is False.

Check valves are designed to allow the flow of fluid or gas in one direction only. They are used to prevent backflow, ensuring that the flow goes in the desired direction.

For example, in the human respiratory system, the tricuspid valve and the bicuspid (mitral) valve are check valves that prevent the backflow of blood from the ventricles to the atria.
