Question

During inhalation, the diaphragm:

Moves downwards

Moves upwards

Moves towards left

Moves towards right​

Answer 1

Exhalation is the flow of the breath out of an organism. In humans, it is the movement of air from the lungs out of the airways, to the external environment during breathing.
During exhalation, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity. As they relax they position rib cage downwards and inwards.
As the space in the chest cavity gets smaller, the air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.
Hence During exhalation, the ribs move downwards.
So, the correct answer is 'Move downwards'.
