you breathe in and out or you would die!!!! <><><> The movement of the diaphragm is what causes the air to go in and out of your lungs.
the diaphragm pushes up and the air flows out the diaphragm pushes down and the air flows in
When the diaphragm contracts the air is pushed out to the lungs and we breath. also when you project your voice you diaphragm rises causing you to take deeper breaths- this is why you breath more when you project your voice\sing etc
The movement of the diaphragm and intercostal muscles changes the volume of the thoracic cavity during breathing. When the diaphragm contracts and moves downward, it increases the cavity's volume, causing air to be drawn into the lungs (inhalation). Conversely, when the diaphragm relaxes and moves upward, the volume decreases, forcing air out of the lungs (exhalation). This pressure change is essential for the airflow in and out of the respiratory system.
Respiration. The diaphragm is a sheet of muscle separating the chest cavity from the abdominal cavity which, when relaxed, domes upwards; on breathing in the diaphragm contracts & flattens down, thus increasing the capacity of the chest, and causing air to be drawn into the lungs.When the diaphragm contracts that causes the volume of the lungs to increase. When the lung volume increases, the air pressure drops causing air to come in from outside (inhaling). When the diaphragm relaxes, the process is reversed. Lung volume decreases, air pressure builds, and air is forced out (exhaling).
When you breathe out the diaphragm moves upwards to push the air out of the lungs. When you breathe in the diaphragm moves downwards to draw air into the lungs. When you breathe out your diaphragm contract and moves upwards towards your head. when you breathe in too much your diaphragm explodes
Your chest rises and falls during breathing due to the movement of the diaphragm and intercostal muscles. When you inhale, the diaphragm contracts and moves downward, while the intercostal muscles expand the rib cage, increasing the volume of the thoracic cavity and allowing air to flow into the lungs. Conversely, when you exhale, the diaphragm relaxes and the rib cage contracts, pushing air out of the lungs. This rhythmic movement is essential for gas exchange in the body.
Hiccups are caused when you have contractions of the diaphragm. The diaphragm is what makes your lungs take in oxygen and expel it.
Your diaphragm is dome shaped structure. You need to see the same in cadaver. when your diaphragm contracts, it becomes some what flat. This increases the volume of thorax and air rush in.
since there is no answer to this, im just going to go ahead and guess : the lungs .
When you breath, your lungs can go up and out a little, but mostly, your lungs go down. The breathing device is the diaphragm, a sheet of muscles going across your chest inside front to back. As the diaphragm 'bends' itself down, the lungs have to move with it and get bigger. When the lungs get bigger, they have no choice but to suck in more air through the mouth or nose. When the diaphragm 'bends' or moves upward, air is pushed out of the lungs.
Contractions of the diaphragm and the intercostals muscle change the size of the thorax. Because of this, it causes air to move in and out of the lungs. The circulatory system releases CO2 or gaseous wastes to the lung where it is exhaled from the body
