When it contracts it causes a very significant increase in the volume of the thorax, thus reducing the pressure inside and causing negative pressure in relation to outside. Hence air moves inwards, due to the pressure difference and thus inhallation is accomplished. The reverse occurs in exhallation.
What else can I help you with?
What is the muscle that stretches across the upper chest?
The thin sheet of muscle is called the diaphragm. It relaxes and contracts to help us inhale and exhale.
Does your chest expand because your lungs inflate or do your lungs inflate because your chest expands?
There are no muscles in the lungs that help inhale or exhale, this is the job of the diaphragm.
What is that curvy thing called under your lungs and how does it help us?
The curvy thing under your lungs is called the diaphragm. It plays a crucial role in respiration by contracting and flattening when you inhale, creating more space for the lungs to expand and draw in air. When you exhale, the diaphragm relaxes and moves back up, helping to push air out of the lungs.
Proper breathing requires inhalation and exhalation You are breathing properly when your abdomen becomes distended when you inhale and lowers when you exhale?
Proper diaphragmatic breathing involves distending the abdomen during inhalation. Lie comfortably on your back and put one hand on your abdomen and the other on your chest and inhale. If your chest rises first, you're doing it incorrectly. The abdomen should rise first and continue rising upward. Inhale in one continuous and effortless motion. When you exhale the chest should deflate first, followed by the abdomen, again effortlessly. it's important to be calm when doing this. Do not exert too much effort in doing so.
What causes the diaphragm to contract?

When lifting a weight should you exhale or inhale?
Inhale and exhale whenever you need to. If your workout involves swimming, you may need to hold your breath when under water. If your workout involves lifting weights, you may find it helpful to inhale just before lifting. But in general, you should simply breath normally.
What happens to the rib cage when inhaling and exhaling?
it expands as we inhale and contrasts as we exhale...this allows our lungs to fill up with air without pushing on out rib cage the rib cage moves up and out when inhaling and moves down and in when exhaling.
Does a paper bag help with hyperventilation?
Yes, paper bag is long years ago use for hyperventalation the logic here is that you rebreath the air you exhale. This helps the you to inhale more CO2 (air that you exhale) back into your bloodstreams. And this works.
How does the diaphragm works?
The diaphragm is a dome-shaped muscle located beneath the lungs that contracts and flattens when you inhale, creating a vacuum in the chest cavity that allows air to rush into the lungs. When you exhale, the diaphragm relaxes and returns to its dome shape, pushing air out of the lungs. This process of contraction and relaxation allows for breathing to take place.
How do your muscles below your lungs and between your ribs help you inhale?
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.

Is the exchange of air between the human body and the environment the result of coordinated contractions of the muscles of the rib cage and the lungs?
Yes, the exchange of air between the human body and the environment involves the coordinated contractions of the muscles of the rib cage and the diaphragm, which help expand and contract the lungs. When we inhale, the diaphragm and intercostal muscles contract to expand the thoracic cavity, allowing air to be drawn into the lungs. When we exhale, the diaphragm and intercostal muscles relax, causing the thoracic cavity to decrease in size and push air out of the lungs.
