Does the diaphragm need to go down to breath in?
The diaphragm moves down and contracts, flattening itself, when you inhale.
When the diaphragm moves up do you inhale?
No, as you inhale the diaphragm is contracting and pulling down, expanding the lungs. As you breathe out, the muscle relaxes and rises up again.
What causes the air pressure in your lungs to decrease and make you inhale?
When you inhale, oxygen fills your lungs. Next the oxygen diffuses out of your lungs into your bloodstream. The diffusion of oxygen from the lungs causes less pressure in your lungs signaling your brain that you need to inhale.
When a person exhales what happens to the diaphragm?
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.
When you inhale what direction does the diaphragm move?
Upwards, toward the head.
Does the diaphragm need to go down to breath in?
The diaphragm moves down and contracts, flattening itself, when you inhale.
When you inhale what contracts and moves down the bronchioles nephrons diaphragm or kidneys?
When you inhale, your diaphragm contracts dropping down causing negative pressure in your thoracic cavity(lung area) so that air can circulate through the lungs.
Does your diaphragm contract and move down when you inhale or exhale?
you inhale when your diaphragm contracts.
What happens to the diaphragm when you inhale and when you exhale?
When the diaphragm contracts and moves lower, the chest cavity enlarges, reducing the pressure outside the lungs. To equalize the pressure, air enters the lungs. When the diaphragm relaxes and moves back up, the elasticity of the lungs and chest wall pushes air out of the lungs.
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.
What allows the lungs to move freely in the thorax due to the secretion of a serous fluid?
When you inhale your diaphragm contracts and moves down allowing some extra space. The muscles between your ribs also contract forcing them out also allowing more space. So there is more wiggle room for the lungs when you inhale.
When the diaphragm moves up do you inhale?
No, as you inhale the diaphragm is contracting and pulling down, expanding the lungs. As you breathe out, the muscle relaxes and rises up again.
What causes the air pressure in your lungs to decrease and make you inhale?

What happens to the rib cage when inhaling and exhaling?
it expands as we inhale and contrasts as we exhale...this allows our lungs to fill up with air without pushing on out rib cage the rib cage moves up and out when inhaling and moves down and in when exhaling.
What muscle moves down when you inhale and up when you exhale?
During passive breathing the diaphragm moves down for inhalation this pushes the organs of the abdomen down and so pushes the rectus abdominus out, this is why you see your abdomen moving. To assist exhalation the rectus abbominus then contracts pushing the organs back in and so pushing hte diaphrag pack up.
What happens to the diphgram when you inhale?
The diaphragm is a convex shaped muscle (convex side within the chest cavity).When the diaphragm muscle contracts it flattens out and drops down out of the chest cavity making more room and creating a vacuum -- air then rushes into the lungs.When the diaphragm relaxes it moves back up into the chest cavity and expels the air on the lungs. During inhalation, the increased volume of the lungs causes the ribcage to expand. Inhalation - Diaphragm CONTRACTS and moves DOWN (to allow more space in the chest cavity for lungs to expand).Exhalation - Diaphragm RELAXES and moves UP (to force air out of the lungs).
What is the changes in size of thoracic cavity during the contraction and relaxation of diaphragm?
When the Diaphragm contracts, it is pulled down, and is pulled back up when it relaxes.Also, when you inhale, it contracts. When you exhale, it relaxes.
