Likewise, what is the diaphragm and what does it do?Diaphragm (muscle): The muscle that separates the chest (thoracic) cavity from the abdomen. The diaphragm is the main muscle of respiration. Contraction of the diaphragm muscle expands the lungs during inspiration when one is breathing air in.One may also ask, how does a diaphragm work? A diaphragm keeps sperm from entering the uterus by covering the cervix. For added protection, spermicide is put into the bowl of the diaphragm and along its edges before it’s inserted. The diaphragm is placed high into the vagina so it covers the cervix. In this way, what is the role of diaphragm in human respiration? Diaphragm’s Role in Breathing When the diaphragm contracts and moves lower, the chest cavity enlarges, reducing the pressure inside 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 is the role of diaphragm during inhalation and exhalation?Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs.
