When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand.
The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.As your lungs expand, air is sucked in through your nose or mouth. The air travels down your windpipe and into your lungs. After passing through your bronchial tubes, the air finally reaches and enters the alveoli (air sacs).

How long can you breath without your diaphragm working due to nerve damage?
Without the diaphragm working due to nerve damage, a person may only be able to breathe for a few minutes before experiencing severe respiratory distress and potentially losing consciousness. Emergency medical intervention such as mechanical ventilation would be required to sustain breathing in such a situation.
Why do people hold their breath when they laugh?
People often hold their breath when they laugh due to the involuntary nature of laughter, which can lead to the diaphragm contracting and temporarily interrupting normal breathing patterns. This pause allows for the buildup of tension and can enhance the physical experience of laughter.
