The diaphragm. (located beneath the lungs) When it contracts it moves down, thus expanding the volume of the lungs. This causes the pressure in the lungs to decrease and air to flow in to the lungs. (pressure is inversely proportional volume- Boyle's law) This is inhaling.
When the diaphragm relaxes it moves back up, decreasing the volume of the lungs and increasing the pressure which forces the air out. This is exhalation.
What else can I help you with?
What is the name of the muscle that helps your lungs fill wit air?
Diaphragm
What organ expands to fill with air?
Lungs expand to fill with air. It is done during respiration.
What carries air into your lungs?
when you contract your diaphram, or the lung muscle, your lungs become somewhat empty. this is called a partial vacuum. this is something that air, water, anything that can go in try to fill. the lungs, now a vacuum, pull stuff, supposed to be air!,into the lungs.
Is the lungs a muscle?
Lungs are not muscles. They are made up of connective, epithelial, and nervous tissues. The diaphragm is the muscle that contracts and relaxes to expand and relax the chest cavity. Your lungs just fill with air -- which is why they appear to be moving (much like a when a balloon fills with air).
How does your diaphragm allow breathing?
The diaphragm is a dome-shaped muscle located below the lungs. When it contracts, it flattens out, creating more space in the chest cavity, which allows the lungs to expand and fill with air. This process facilitates inhalation and is essential for breathing.
What muscle is responsible for helping you breathe?
The diaphragm muscle is responsible for helping you breathe by contracting and expanding to create space for the lungs to fill with air.
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.
The muscle that the lungs rely on to take in and expel air is what?
The diaphragm is the main muscle responsible for breathing. When it contracts, it enlarges the chest cavity and creates a vacuum that allows the lungs to expand and take in air. When it relaxes, the chest cavity decreases in size, forcing air out of the lungs.
What structure is primarily responsible for keeping us breathing?
the lungs fill with air because the diaphragm (a muscle that runs underneat the ribcage) moves and causes the lungs to inflate
What is your diaphram?
The diaphragm is a dome-shaped muscle located beneath the lungs and separates the chest cavity from the abdominal cavity. It plays a vital role in the process of breathing by contracting and expanding to help draw air into the lungs and then expelling it.
What is the function of the diahragm?
The diaphragm is a dome-shaped muscle located below the lungs. Its main function is to help with breathing by contracting and expanding to create a vacuum that allows the lungs to fill up with air during inhalation and push air out during exhalation.
What are organs that expand to fill with air?
do you mean fills with air? if so then its the lungs
