What happens to the volume of your chest cavity when you inhale?
When you inhale the volume increases, because the chest cavity expands to hold your breath.It increases.
The intercostals are located?
The intercostal muscles are located between the ribs. They play important roles in breathing. There are two sets of intercostal muscles, external and internal. The external intercostals contract during normal inspiration, causing the rib cage to expand out and up and thus increase the volume of the chest cavity. The internal intercostals are used during forced expiration only. When they contract, the rib cage pulled down and together, shrinking the volume of the chest cavity.
What are the muscles involved in changing the volume of the thorax during breathing?
There are several muscles that are responsible for breathing. They are the Diaphragm, the external intercostal muscle, and the internal intercostal muscle.
What state of matter does not change in volume?
Changes in the states of matter - or phase changes - do entail changes in volume.
When you heat a cool substance does the mass or volume change?
No, the mass and volume stay the same but the shape changes. Changes in state never change it's mass but if it changes to gas, the volume is unmeasurable.
Do intercostal muscles change the volume of the thoracic cavity?
Yes. Along with the diaphram.
What causes air to move into and out a persons lungs?
1) Pressure changes caused by 2) your chest muscles PLUS your rib cage cause the volume of your thoracic cavity to change.
Which describes the action of the diaphragm and chest cavity when you exhale and squeeze air from the lungs?
it will changes the air pressure in the thoratic cavity by increasing or decreasing the thoratic volume
What is the first event in expiration?
The first event in expiration is the relaxation of the diaphragm muscle, which is the primary muscle responsible for breathing. As the diaphragm relaxes, it moves upward, decreasing the volume in the chest cavity and causing air to be expelled from the lungs.
What roles do the diaphragm and intercostal muscles play in breathing?
because it divides the chest from the abdomen
What happens to the volume of your chest cavity when you inhale?
When you inhale the volume increases, because the chest cavity expands to hold your breath.It increases.
What happens to the volume of his chest cavity when he inhales?
The volume of the chest cavity is reduced on exhalation. Imagine your lungs are balloons. Imagine the volume of a balloon full of air, compared to when it is not inflated. The balloon has a greater volume when it is inflated than when it is deflated - just like the lungs do!
What is the name of the large flat muscle that moves up and down in changes the volume of air in the chest cavity?
It's called - the diaphragm (pronounced di-a-fram)

Describe how the diaphragm and rib cage function in moving air out of a mammal's lungs?
The thoracic cavity (the chamber that holds the lungs and heart) is separated from the abdominal cavity by a muscular sheet, the diaphragm. When relaxed, the diaphragm bows into the thoracic cavity, decreases the volume of the cavity, and with contraction of abdominal muscles forces air out of the lungs; when the muscles of the diaphragm contract, it becomes taut and flat, increasing the volume and lowering the pressure of this cavity, drawing air into the lungs. To support their high energy demands for oxygen, mammals must be able to breathe while they suckle, chew food, or clutch prey in their jaws. This capacity is provided by the secondary palate, a shelf of bone forming the roof of the mouth, which separates the mouth from the nasal passages. sex
What happens to your ribs when you inhaled?
they expand, or get biggerThe contraction of your intercostal muscles causes the rib cage to move up and out, thus increasing the volume of the thoracic cavity, decreasing the pressure, so air is forced in.If you're asking for GCSE, the term you need to use is the "ribs move up and out". Don't forget the contraction of the diaphragm, as it flattens it aids the increase in volume of the thoracic cavity.
