What happens to the diaphragm when a person inhales?

Answer 1

The diafragm moves downward and the intercostal muscles contract pushing the chest outward and upward causing negative pressure in the lung structure - air will allways move from a high pressure area to a low pressure area, hence, into the lungs.

Answer 2

The diaphragm, a wide, flat muscle that separates your lungs from your intestines, bulges downward. This movement pulls the lungs down, making them longer up and down. There can be only one response: the lungs fill with extra air to fill the new, bigger lung size.

When the diaphragm comes back up out its bulge, the lungs are pushed upward, making them smaller. The response is for the lungs to push air out of the body. This whole cycle is called a breath. (Pronounced Breth)

Answer 3

When you inhale, the diaphragm contracts and moves down. This increase the chest cavity and the lung volume.

Answer 4

Contracts and flattens because the lungs expand.

Answer 5

When you breathe in, your diaphragm contracts. This makes the diaphragm move lower and increases the area in your lungs.

Answer 6

When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand.

Answer 7

it will move downwards
