What else can I help you with?
What is the muscle that contracts and relaxes so that you can breath is the?
It is called your diaphragm.
Why does the diaphragm and relax when you breath?
The dipahragm is innervated by the phrenic nerve. This nerve responds to the stimulus sent by the a very particular set of neurons located in the medulla. The main ones are called VRG and DRG. Of these the VRG sends signals to the diaphragm to contract, when the signal is not "on" then the diaphragm relaxes. DRG modulates the depth of breath. There is another group called the pneumotaxic center found in the ponds; this group keeps the VRG in check. If the frequency of respiration becomes too great the pneumotaxic center inhibits depolarization of the VRG for a while in an attempt to restore a "normal" breathing pattern
What is the process called when the lungs are getting bigger and smaller?
The process of the lungs getting bigger and smaller is called respiration, specifically during inhalation and exhalation. During inhalation, the diaphragm contracts and moves downward, expanding the chest cavity and allowing air to enter the lungs. Conversely, during exhalation, the diaphragm relaxes, the chest cavity decreases in size, and air is expelled from the lungs. This cycle is essential for gas exchange in the body.
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.
What parts of the respiratory system when you inhale?
answer: diaphragm at the bottom of the chest cavity is a muscle called the diaphragm. when the diapragm contracts, the chest cavity becomes larger.
What muscle separates the thorax and abdomen and aids in breathing?
The muscle that separates the thorax and abdomen and aids in breathing is called the diaphragm. It is a dome-shaped muscle that contracts and relaxes to regulate the volume of the thoracic cavity, allowing for inhalation and exhalation.
What part of the respiratory system contracts when you inhale?
answer: diaphragm at the bottom of the chest cavity is a muscle called the diaphragm. when the diapragm contracts, the chest cavity becomes larger.
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.
How does air move in and out of your lungs?
You know, there is a muscle under the lungs. It is called diaphragm. It tightens and relaxes as you breathe. It goes through the bronchial tubes then up the windpipe, then out, then it comes back in. The windpipe is also called trachea. That's all I know.
What is it called when your heart contracts and relaxes?
Diastolic and systolic is when your heart contracts and relaxes.
What is the sheet of muscle located between the chest and abomen?
it is called the diaphram.
When one muscle contract what does the other muscle do?
The other relaxes. This other is called the antagonist. The one contracting is called the agonist.
