What happens to the volume of your chest cavity when you inhale?
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.
What happens to your chest when you inhale?
When you inhale, the chest cavity expands. Seventh grade life science, baby.When you breathe in, 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.
Do you inhale or exhale when the diaphragm expands and arches upward?
When the diaphragm expands and arches upward, it creates more space in the chest cavity, allowing air to rush in. This is called the inhalation phase of breathing, so you would be inhaling during this process.
Do you in hale or exhale when the volume of the chest cavity increases?
The air pressure in your chest cavity increases when you are exhaling. For air to leave your lungs, it must be at a higher pressure than the air outside. Your diaphragm pushes up against your chest cavity causing the space in your lungs to get smaller. If the volume decreases, the pressure has to rise. Don't believe me? start exhaling, then close your mouth. Your cheeks will puff out because the pressure inside is greater than the pressure outside.
What position is the diaphragm when relaxes?
In the human body, the diaphragm separates the thoracic and abdominal cavities. When a person sits in an erect position, the diaphragm moves in an up and down motion, sort iof like an accordion.
What happens to the diaphragm when you inhale and when you exhale?
When the diaphragm contracts and moves lower, the chest cavity enlarges, reducing the pressure outside the lungs. To equalize the pressure, air enters the lungs. When the diaphragm relaxes and moves back up, the elasticity of the lungs and chest wall pushes air out of the lungs.
What happens when the muscle in your chest moves to cause you to exhale?
When you breathe out, or exhale, your diaphragm and rib muscles relax, reducing the space in the chest cavity. As the chest cavity gets smaller, your lungs deflate, similar to releasing of air from a balloon
What happens to the volume of your chest cavity when you inhale?

How does air enter and exit our lungs?
Much like as in a concertina or a piano accordian. Body muscles increase the volume of the chest, and air rushes in to occupy the extra space. Then the body muscles reduce the volume and to avoid being pressurised the air is pushed out.
What layer of muscles move up and down when you breath?
The diaphragm is a muscle that moves or pushes up your lung when you exhale and down when you inhale in order to allow more space for oxygen to fill your lung. Also, your chest expands as you breath in and relax as you exhale.

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 can you infer about the function of the diaphgram?
The diaphragm is a muscle located beneath the lungs that plays a key role in the process of breathing. When you inhale, the diaphragm contracts and moves downward, creating more space in the chest cavity for the lungs to expand and take in air. When you exhale, the diaphragm relaxes and moves back up, helping to push air out of the lungs.

Are you breathing in or out when the diaphragm contracts?
contracts means to come together or to close. Try breathing. Does your diaphragm get smaller when you inhale or exhale? ********************************************************** Hint: it contracts when you inhale..
