What causes air to stop moving into the lungs during inspiration?

Air stops moving into the lungs when the air pressure inside the lung is equal to the pressure of the air outside the body (the atmospheric pressure). The body creates negative air pressure inside the lungs by moving the diaphragm down and the chest wall out. This expands the volume of the lungs, creating negative air pressure, and air rushes in to fill the lungs.

∙ 13y agoI think you mean "inhalation", since "inspiration" is when an idea goes into the head, not when air goes into the lungs.
When you inhale, your lungs expand, like a balloon. This is effected by the simultaneous expanding of the chest via the intercostal muscles of the rib cage (pulling the lungs out and up) and the contraction of the diaphragm (pulling the lungs down).
A balloon, if expanded in the tub, would fill up with water. Likewise your lungs fill up with air when expanded.
But if you really meant "inspiration", then the answer is equally simple: You have to take a breath before you say "Aha!"

Period of breathing when air leaves the lungs?
Inspiration.
How does the expansion of the chest wall expand the lungs during inspiration?
the air goes up to the chest cavity. Hope this helps you!
Moving muscles in order to make air flow into and out of the lungs?
The term for moving muscles in order to make air flow into and out of the lungs is breathing. The main muscle that moves is the diaphragm, which sits just below the lungs and causes air to flow in and out as it contracts and expands.
When air passes out of the lungs it is inspiration?
When air passes through your lungs it is called respiration.
When does inspiration occur?
when atmospheric pressure is greater than the pressure within the lungs, inspiration occur.
In which process is it when oxygen enters the lungs?
Inhalation/Inspiration
Why does air rush into the lungs during the process of breathing?
Air enters the lungs because the pressure in the atmosphere is greater than the pressure in the lungs. Lung pressure is lowered by increasing the volume of the lungs. This is achieved by lowering the diaphragm and raising the rib cage.
What is inspiration and exhalation?
Inspiration, as called inhalation, moves air into the lungs. Expiration, as called exhalation, moves air out of the lungs.
What is the result of inspiration and expiration?
This occurs within the respiratory system. During inpiration, the intercostal muscles contract, the diaphragm descends, and the rib cage rises. The thoracic cavity volume increases, stretching the lungs, and the intrapulmonary volume increases. This causes the intrapulmonary pressure to drop. Air flows into the lungs until the intrapulmonary pressure equals the atmospheric pressure. During expiration the intercostal muscles relax, the diaphragm rises, and the rib cage descends. The thoracic cavity volume decreases, causing the the lungs to recoil, and the intrapulmonary volume decreases. This causes the intrapulmonary pressure to rise, and the air flows out of the lungs until the intrapulmonary pressure equals the atmospheric pressure.
Is pressure highest in the lung when lungs are full after inspiration or empty after exhalation?
The pressure is highest in the lungs on complete exhalation.
Respiration is any procedure for causing air to flow into and out of the lungs when natural breathing stop?
The "Resuscitation" part of Cardio-pulmonary Resuscitation (CPR). Alternaltey, you can do this with an Ambu Bag, or intubate and have a machine breathe the patient during surgery
What is the medical definition of the word inspiration?
Inspiration in medical terms refers to the act of inhaling air into the lungs. It is the process by which oxygen is taken into the body and carbon dioxide is expelled during respiration.
