What is diaphragm define and expain it |
|
Answer» The DIAPHRAGM is a THIN skeletal muscle that sits at the BASE of the chest and separates the abdomen from the chest. It contracts and flattens when you INHALE. This creates a vacuum effect that pulls air into the lungs. When you exhale, the diaphragm relaxes and the air is PUSHED out of lungs. |
