What is the function of the diaphragm?

The diaphram is the muscle that allows us to breathe.

The lungs are like a baloon that has been somehow sucked into a plastic bottle, inflating it inside the bottle. If a hole was made in the bottle, the lungs would collapse.
Imagine the base of the bottle is replaced by a rubber membrane representing the diaphram, it would be sucked slightly into the bottle by the lower pressure.
The diaphram tightens, which straightens it, expanding the volume in the bottle, and the lungs expand to fill that extra volume sucking in fresh air.
The diaphram relaxes, gets sucked back upwards, reducing the volume, and the lungs expel the air.

does diaphragm change the volume and pressure in the thoracic cavity?

The diaphragm is an organ that helps during reproduction. This organ can be used when the penis is ejected into the vagina. The female will feel an adrenaline rush from this organ that will help stimulate the boner of the male.

The diaphragm is the muscle that allows us to breathe.
The diaphragm is the primary muscle of inspiration, and as such
uncompromised function is essential to support the ventilatory and gas
exchange demands associated with physical activity. The normal healthy
diaphragm may fatigue during intense exercise, and diaphragm function
is compromised with aging and obesity.

it's the muscle that pulls the lungs open & pushes them close for inhalation & exhalation.
