As the volume of space above the pulled down diaphragm increases, air rushes into the lungs and they inflate, bringing fresh oxygenated air into the respiratory system.
Inhalation
Breathing is done by your diaphragm. When you breathe in, your diaphragm tightens (contracts) and moves downward so your lungs can expand. When you breathe out (exhale) your diaphragm relaxes (expands) and moves up into your chest.
The diaphragm muscles contract and relax pulling the diaphragm down and then releasing it. When we inhale, our diaphragm muscles contracts and flattens. When we exhale, they relax and arch upwards.
Inhalation
the diaphragm helps hold air in and out it is located right below your ribcage. when you sing, it pulses and allows your air to hold for a long time without a breath. The diaphragm is a muscle starting in your back and running to your front below your ribcage. It completely separates the area within your ribcage from the area below. However it does have sealed portals through which vessels and other structures pass. By expanding your diaphragm -- your abdomen will rise because the diaphragm is expanding downward into the abdominal area -- you can create a partial vacuum which helps to draw air into your lungs. Conversely, by relaxing your diaphragm you let air out of your lungs.
When you inhale.
It contracts (and moves downward).

Inhalation
the diaphragm. It is right above the heart and lungs, and expands and contracts when you breathe in and out. You can almost feel it move down a little, when you release air.
When you inhale, your diaphragm contracts and moves downward, and when you exhale, your diaphragm relaxes and moves upward.
the diaphragm contracts and moves downward, and the rib cage moves upward and outward.
In Out In Out In... Normal respiratory movements include rib cage expansion, diaphragm contraction and downward movement, abdominal contractions, lung expansion, opening of veins and arteries in chest, heart rate increase during inhalation and increase of thoracic cavity

The major muscle that the body uses for breathing The above answer is of course correct for the thoracic diaphragm but there are others for example the pelvic diaphragm. A diaphragm is a domed muscular wall the reperates to regions. When is contracts it flattens to increase pressure on the inside of the dome and decrease pressure on the outside of the dome. In the case of the pelvic diaphragm is domes downards and contracts to resisf the increased pressure from the thoracic diaphragm on the abdomen during inhalation.
it decreases because of abdominal compression of organs due to displacement by the enlarged uterus which nullifies the abdominal respiration and downward movement of diaphragm to aid respiration is also decreased
A hiccup is the movement of the diaphragm. The diaphragm is in the thoracic cavity just under the lungs. This organ helps to squeeze the lungs when you exhale in order to get all the air out of the lungs. Holding your breath causes the diaphragm to move downward and stop this movement.
