Question

What is bulk flow in respiration?

Answer 1

Bulk flow:

1. The gas movement ( carbon dioxide and oxygen) to a low-pressure area is called bulk flow in respiration.
2. This mechanism involved in breathing is responsible for the shape and volume changes of the chest cavity, which is controlled by the muscles of the respiratory system.
3. Bulk flow is analogous to the flow of water through a pipe or the flow of blood through a blood vessel.
