The diaphragm is a dome-shaped muscle located underneath the lungs. When you inhale, the diaphragm contracts and moves downward, creating more space in the chest cavity for the lungs to expand and fill with air. When you exhale, the diaphragm relaxes and moves back up, pushing the air out of the lungs.
The 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.
Yes, 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.

What muscles do children use to breathe?
Children primarily use their diaphragm and intercostal muscles to breathe. The diaphragm contracts and moves downward, expanding the chest cavity, while the intercostal muscles between the ribs help to further expand the chest for breathing in.
Describe how the diaphragm and rib muscles work together to control inhaling and exhaling?
The diaphragm contracts and moves downward during inhalation, increasing the volume of the chest cavity and drawing air into the lungs. The rib muscles, such as the external intercostals, help expand the chest wall outward to create more space for the lungs to fill with air. During exhalation, the diaphragm relaxes and moves upward, while the rib muscles relax and help decrease the volume of the chest cavity, forcing air out of the lungs.

Why do you need a diaphragm?
A diaphragm is a contraceptive device used during sexual intercourse to prevent pregnancy. It is a barrier method that covers the cervix and blocks sperm from entering the uterus. It needs to be used in combination with spermicide for efficacy.
Movement of the diaphragm during inhalation?
During inhalation, the diaphragm contracts and moves downward. This action creates more space in the chest cavity, allowing the lungs to expand and fill with air. The downward movement of the diaphragm also causes the ribcage to expand, further facilitating the intake of oxygen.
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
What parts of the body work together to help you breathe?
The diaphragm, intercostal muscles, and lungs work together to help you breathe. The diaphragm moves down, the intercostal muscles expand the rib cage, and the lungs expand to take in air for oxygenation.
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.
When you breathe in the diaphragm goes up or down?
The diaphragm goes downwards.
Do you need a diaphragm?
The diaphragm is the main muscle used in breathing, if you can't breathe you die.

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.
What muscles do children use to breathe?
Children primarily use their diaphragm and intercostal muscles to breathe. The diaphragm contracts and moves downward, expanding the chest cavity, while the intercostal muscles between the ribs help to further expand the chest for breathing in.
What part of the body helps us breathe in?
The diaphragm relaxes to help squeeze the air out of your lungs. When the diaphragm contracts, it flattens and pulls air into your lungs. When it relaxes into its dome-shaped position, air is pushed out.
