Diaphragm
Diaphragm:
Lungs are situated inside the chest cavity, and they rest on a large muscular sheet called the diaphragm, which forms the floor of the chest cavity. Diaphragm is a membrane which is present between the chest and abdomen. When you breathe in, your diaphragm and rib cage get into action. The diaphragm is protected by rib cage. The diaphragm plays an important role in inhalation and exhalation.
The breathing is controlled by the movement of diaphragm. The movement of diaphragm is controlled by a group of muscles called intercostal muscles.
When the diaphragm moves downwards, the rib cage expands. This leads to the expansion inside the lungs.
