Diaphragms are essential components in various mechanical and biological systems, serving as flexible barriers or partitions. In mechanical applications, a diaphragm is a thin, flexible material that can deflect or vibrate when a pressure difference is applied across it. This deflection can be used to actuate valves, pumps, or pressure-sensitive instruments. For example, in a diaphragm pump, the movement of the diaphragm draws fluid into a chamber and then expels it. In pressure gauges, the diaphragm's deformation under pressure is translated into a reading on a dial. Diaphragms are often made from materials like rubber, silicone, or metal alloys, chosen for their flexibility, durability, and resistance to the specific environment they will operate in.

Biologically, the diaphragm is a large, dome-shaped muscle located at the base of the chest cavity that separates the abdomen from the chest. It plays a crucial role in respiration. When the diaphragm contracts, it flattens and moves downward, increasing the volume of the chest cavity. This causes air to rush into the lungs, a process known as inhalation. When the diaphragm relaxes, it returns to its dome shape, decreasing the chest cavity volume and forcing air out of the lungs during exhalation. This involuntary muscle action is the primary driver of breathing for most individuals. The diaphragm's ability to contract and relax rhythmically is fundamental to maintaining oxygen levels in the body.
