Respiration is a process which involves taking in of oxygen through inhalation to supply to the tissues and release of carbon di oxide through exhalation from tissues to the atmosphere. During inhalation the rib cabe expands by moving out. The diaphragm moves down. These two process occur simultaneously to increase the air holding capacity of the lungs by expanding the alveolar cells of lungs.

ANSWER:The expansion of the lungs during the process of inhalation or breathing in and then again during exhalation or breathing out.Muscles. Specifically the intercostal muscles between the ribs and the muscles that lift and spread the ribs. This, with the diaphragm, causes a low pressure area, internally, which causes the air to flow into the lungs.

∙ 10y agoThese are the muscles that move the rib cage and they work together:
- Diaphragm (Prime mover of inhalation). If you need to breathe deeper you will use these:
- Scalenes (Elevate rib cage, assist in inhalation)
- Sternocleidomastoid (Elevate Rib Cage, assist in inhalation)
- Pectoralis minor (Elevate Rib Cage, assist in inhalation)
- External Intercostals (Elevate rib cage, assist in inhalation)
- Internal Intercostals (Depress, assist in exhalation)
The diaphragm is under both voluntary control (holding your breath) and involuntary control (sleeping, reading)

Are the ribs immovable or movable?
Ribs move with the diaphragm to assist in breathing. While they are fairly rigid, just look at how your chest expands and contracts while breathing. If they were immovable, there would be no movement.
Which muscies is responsible for inspiration when breathing?
The diaphragm, a sheet of muscles spanning the rib cage just below the lungs, is mainly responsible for both inspiration and expiration. The intercostal muscles are also used, expanding and contracting the the space between the ribs. The abdominal muscles are used to a lesser extent either by relaxing to allow further expansion of the diaphragm or contraction for rapid expulsion of air. (Note to the person who answered this question previously: "Inspiration" means to inhale. "Expiration means to exhale. Don't tell someone that they don't know what they are talking about unless you know what you are talking about.)
What is the function of the diaphragm and ribs?
Ribs: The ribs protect the lungs and expand as you inhale to facilitate space for the lungs to expand like the diaphragm. The ribs then contract expelling the air in the lungs. The ribs enclose the thoracic cavity providing bony protection for the vital organs of the thorax's heart and lungs.
What is a diaphragm of chest cavity?
The chest cavity is where your heart, lungs, and esophagus reside. It's essentially everything located behind the chest wall, but in front of the spine, above the diaphragm and below the throat.
How many times do your ribs move every year?
yes.yor ribs move 5 million times a year, everytime you breathe!
What are you doing when your diaphragm moves up and your ribs move down and in?
Your diaphragm lowers and your ribs expand outwards
How do the lungs take in and breathe out?
During inspiration the ribs move upwards and outwards and the diaphragm contracts ,thus,increasing the volume of the thoracic cavity.this leads to a decrease in pressure inside the lung.therefore the air from outside rushes in . During expiration the ribs move inwards and downwards and the diaphragm relaxes thus,creating low pressure .this leads to the expulsion of air from our body.
How the process of inhalation take place?
During inhalation (inspiration) the ribs move up and out. Volume in the thorax increases whilst pressure decreases. The diaphragm goes down and the intercostal muscles contract. Just to let you know, exhaling (expiration) is just the opposite to inspiration. :) - Hope I helped :)
What muscle expand chest cavity upward during inspiration?
The diaphragm (a sheet of muscle underneath the ribcage) and intercostal muscles (located between your ribs).
What does the human diaphragm do?
It contracts and relaxes to help pull air into the lungs and push it back out. The diaphragm contracts and moves lower which expands the ribs and allows air to move into the lungs. When it relaxes, the ribs contract and push air back out of the lungs.
Function of ribs and diaphragm in the breathing process?
Ribs are for protection i think and diaphragm is the muscle controlling inhaling and exhaling. Also: the rib muscles can help the breathing process, which is useful when the diaphragm is weak, constricted, or to get an extra-big breath. Breathing from the diaphragm makes the belly move in and out as the lungs extend downwards. Breathing from the rib muscles makes the chest expand and rise.
Name of muscles between ribs?
The intercostal muscles. Intercostal means "between ribs".
Are the ribs immovable or movable?
Ribs move with the diaphragm to assist in breathing. While they are fairly rigid, just look at how your chest expands and contracts while breathing. If they were immovable, there would be no movement.
Is rectus abdominis a muscle of inspiration?
Actually, no. The rectus abdominis is a muscle that helps with the digestion of food, helps to hold organs in one place and gives you the "6 pack" feature when doing sit ups. There are two other muscles on the ribs that help the lungs with inspiration. They are the Intercostalis muscles. One is on the ribs themselves and one is on the gaps between the ribs. They move the ribs in and out with the lungs with every inspiration and expiration. Hope this helps!
What makes the chest cavity larger when you inhale?
the diaphragm, chest muscles, ribs and the sternum.
What happens to the ribs and diaphragm when you breathe in?
The diaphragm goes down, pulling air into the lungs. Your ribs expand, helping your lungs to expand also.
Air is forced into the lungs by the contraction of the?
Actually, air isn't forced into the lungs my the contraction of any muscle, but by the relaxation of the Diaphragm, along with the Intercostalis muscles on the ribs and the smooth muscle on the lungs. When your diaphragm contracts, it pushes air out of your lungs. When it relaxes, air is drawn in to the lungs. The intercostalis muscles also help move the ribs when the lungs move as your breath. There is one set on the ribs and one set in between each rib.Hope this helps!
