There are no muscles in the lungs that help inhale or exhale, this is the job of the diaphragm.
When you breathe in, your chest expands as the diaphragm muscles contract and move downward. This creates more space in the chest cavity, allowing the lungs to expand and fill with air. The expansion of the chest is essential for the process of inhalation.
because the lungs can not re-inflate themselves
When you inhale, the volume of your chest cavity increases. This expansion is caused by the contraction of the diaphragm and intercostal muscles, allowing more space for the lungs to expand and fill with air.
Action of the diaphragm causes healthy lungs to inflate in whole like a balloon.Doctors have said that the average person does not breath properly, thereby not filling our lungs with sufficient air to help purify our blood. We should do daily exercises of deep beathing or get into the habit of breathing more deeply than we do.
This is a pneumothorax or collapsed lung. It is generally brought on by a puncture in the chest that allows air into the chest cavity outside the lung. As the diaphragm expands, air is drawn in through the hole in the chest wall, and the lung will not fully expand. After a short period and continued respiration, the lung will not be able to inflate. Gas exchange will then be seriously reduced or not occur at all, and the victim willl rapidly begin to suffocate. Use the link below for more information.
It expands
When you inhale, your diaphragm contracts and moves downward, while your rib cage expands. This creates more space in your chest cavity, allowing your lungs to fill with air. The expansion of your chest allows for increased air intake and helps with proper oxygenation of your body.
the chest cavity expands.
The doctor will make an incision under the arm, to insert a chest tube. This chest tube will drain off any blood in the lungs, allowing it to re inflate.
Respiratory compliance refers to the ability of the lungs and chest wall to expand and contract in response to changes in pressure. It is a measure of how easily the lungs can stretch and how well they can return to their resting state. High compliance means the lungs are flexible and easy to inflate, while low compliance means they are stiff and difficult to inflate.
Our chest will expand.
When you breathe in, your diaphragm muscle contracts and moves downward, causing the chest cavity to expand. This expansion lowers the air pressure in the lungs, allowing air to flow in through the nose or mouth.
