The diaphragm divides your torso into two parts. the upper part, the chest or thorax, houses the lungs. When the diaphragm pull down, it forces air into the lungs. Whenthe diaphragm pushes up, it forces air out of the lungs.l

∙ 14y agoThe diaphragm is very important skeletal muscle in breathing process. Infact, muscular effort at rest is only required for Inspiration and expiration is a spontaneous process when the muscular effort is halted at the end of inspiration. The diaphragm when contracts, causes an increase in vertical diameter of the thoracic cavity (air tight) in which lungs are floating (due to slight negative pressure). This increase in vertical diameter creats more negative pressure causing the lungs to expand towards the expanding chest walls outwards. The epiglottis is open and the air finds its way to rush in the bronchial tree and the lungs alveoli. Expiration process is simply the reverse of above mentioned algorithm when the diaphragm relaxes.

∙ 11y agoYes, the diaphragm is the main muscle involved in respiration (in a resting animal). The contraction and relaxation of the diaphragm is responsible for changing the volume of the thorax - which changes the pressure inside the thorax forcing air in or out.

Why do you need a diaphragm?
The diaphragm is the main muscle used in breathing, if you can't breathe you die.
Why is the diaphragm important?
helps you breathe and separates the lungs form your stomach and intestines
What causes the diaphragm to contract?

Describe how the diaphragm and rib muscles work together to control inhaling and exhaling?
When you breathe, the actions of your rib muscles and diaphragm expand or contract your chest. As a result, air flows in and out.
Movement of the diaphragm during inhalation?
During inhalation, the diaphragm contracts flattening out its usual dome shaped appearance. This has the effect of lengthening the lungs and increasing the intrapulmonary volume. When the volume increases, the pressure drops and air flows into the lungs.
When you breathe in does the diaphragm do?
When you breathe in, your diaphragm contracts. This makes the diaphragm move lower and increases the area in your lungs.
When you breath out which direction does your diaphragm go?
When you breathe out the diaphragm moves upwards to push the air out of the lungs. When you breathe in the diaphragm moves downwards to draw air into the lungs. When you breathe out your diaphragm contract and moves upwards towards your head. when you breathe in too much your diaphragm explodes
The immediate effects of exercise on the Diaphragm and intercostals?
The diaphragm and the intercostals are muscles that help breathing. When you excerise they work harder because it is harder to breathe.
What is diaphragm made of?
your diaphragm is a muscle that helpsyou breathe
When you breathe in the diaphragm goes up or down?
The diaphragm goes downwards.
Why do you need a diaphragm?
The diaphragm is the main muscle used in breathing, if you can't breathe you die.
Do you need a diaphragm?
The diaphragm is the main muscle used in breathing, if you can't breathe you die.

What moves your lungs so you can breathe?
Your diaphragm
Describe the function of your diaphragm and explain how inhaling and exhaling occurs?
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.
What is the sheet of muscle that moves down when you breathe in?
Diaphragm
What muscle compress and move downward when you inhale?
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.
