Conditions like chronic obstructive pulmonary disease (COPD) or asthma can reduce the efficiency of inhalation.
In conditions like Multiple Sclerosis (MS), muscle weakness can impair the diaphragm and chest muscles, resulting in shallow breathing or breathing difficulties.
Inhalation, or breathing in, is the active phase of respiration where air is drawn into the lungs, providing oxygen needed for cellular metabolism. It is a complex process controlled by muscle movements that increase the volume of the chest cavity, lowering the pressure inside and allowing air to enter. The Mechanics of Inhalation
Inhaling brings fresh oxygen into the bloodstream to support bodily functions.
