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
Muscles between the ribs contract, pulling the rib cage up and out. ms inhale
Conditions like chronic obstructive pulmonary disease (COPD) or asthma can reduce the efficiency of inhalation. Inhalation, or breathing in, is the active phase
These movements increase the size of the thoracic cavity, creating lower pressure (negative pressure) inside the lungs compared to the outside air. or breathing in
