What else can I help you with?
Exhalation occurs when what relaxes?
The lungs don't actually contract. all the work is done by muscles in the chest.When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.
Describe the function of your diaphragm and explain how inhaling and exhaling occurs?
Breathing is done by your diaphragm. When you breathe in, your diaphragm tightens (contracts) and moves downward so your lungs can expand. When you breathe out (exhale) your diaphragm relaxes (expands) and moves up into your chest.
How normal breathing occurs in a healthy body?
Air is inhaled through the nose or mouth to the lungs and out the same way. UPDATE: Most humans today breth the opposite way that is suppost to be healthy. We are suppost to inhale with are diaphragm flexing (tummy going out) and exhailing with diaphragm collapsing (tummy going in) Hope that helps!!!
What is used as a model to demonstrate breathing mechanism?
A working model of a human lung or a bell jar model can be used to demonstrate the breathing mechanism. These models typically include a pump to mimic the diaphragm movement, balloons or rubber sheets to represent the lungs, and tubes to simulate the airways. By manipulating these components, one can illustrate how the process of inhalation and exhalation occurs in the human respiratory system.
What is a rubber membrane that separates chambers and flexes when pressure differential occurs?
A diaphragm is a rubber membrane that separates chambers and flexes when a pressure differential occurs. It is commonly used in devices such as pumps, valves, and pressure sensors to control the flow of fluids or gases.
What allows you to inhale and exhale?
Inhalation requires the contraction of the diaphragm, and exhalation occurs when it relaxes.
Could Exhalation occurs when the nose relaxes causing the lungs to contract?
No, exhalation does not occur when the nose relaxes.

What happens when the diaphragm and the rib cage muscles relax?
The diaphragm relaxes during EXHALATION. Your diaphragm flattens when you inhale, creating more space for the lungs to take in more air.
What does the diaphragm muscle do when air moves into the lungs?
The diaphragm moves down to make the lungs expand (inhalation)
Does exhalation occur when the diaphragm and rib cage muscles relax?
Yes, exhalation occurs when the diaphragm and muscles of the rib cage relax.
When the diaphragm contracts does lung volume increase or decrease?
The downward contraction of the diaphragm (below the lungs) decreases the pressure within the lungs by expanding the thoracic cavity. The lungs sag into the cavity, and outside air flows into the lungs.The contraction of the diaphragm allows the person (or animal) to inhale air. When the diaphragm relaxes, it pushes upward on the lungs and exhalation occurs.
What happens to a muscle when it relaxes?
all the muscle filaments move away from each other

What exhalation occurs when the relaxes causing the lungs to contract?
The lungs do not contract. When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the spacein the chest cavity.As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.Breathing out requires no effort from your body unless you have a lung disease or are doing physical activity. When you're physically active, your abdominal muscles contract and push your diaphragm against your lungs even more than usual. This rapidly pushes air out of your lungs.
Identify the key parts of the breathing system?
The key parts of the breathing system are the lungs, trachea, bronchi, diaphragm, and alveoli. The trachea and bronchi are airways that carry oxygen to the lungs, where gas exchange occurs in the alveoli. The diaphragm is the muscle responsible for the process of inhalation and exhalation.
What occurs when the diaphragm and rib muscles contracts?
The diaphragm is a sheet of internal skeletal muscle. when relaxed it's domed shaped smooth muscle. upon contraction it reduces in length hence pulling inward which then increases the lung volume creating a negative pressure relative to the aveoli. This ensures that proper gas exchange occurs. Now when the diaphragm relaxes, it returns back into is dome shape ( longer in length) and pushes upward thereby reduces the lungs volume and increasing the pressure relative to the surrounding thus you exhale. Another simple way to approach it is by playing around with PV=nRT in your head if you must.
