what happens to the rib muscles and the diaphragm when you inhale and hold your breath

- When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale. As your lungs expand, air is sucked in through your nose or mouth.

How you can breathe your way to good health To breathe properly, you need to use your diaphragm, the large sheet-like muscle that lies at the bottom of the chest cavity. To find your diaphragm, sit comfortably or lie on your back on the floor. Place your left hand on your upper chest and your right hand on your abdomen, in the 'gap' of your rib cage. When you breathe in and out, your left hand should remain still and only your right hand should move up and down.

How Your Lungs Work This expansion lowers the pressure in the chest cavity below the outside air pressure. Air then flows in through the airways (from high pressure to low pressure) and inflates the lungs. When you exhale, the diaphragm and intercostal muscles relax and the chest cavity gets smaller. The decrease in volume of the cavity increases the pressure in the chest cavity above the outside air pressure.

Lungs - your lungs Below your lungs is the diaphragm (say dye-a-fram). This is a big muscle that works with your lungs to get air in (inhale) and out (exhale). You can feel how they work together. Put one hand on your chest and the other on the upper part of your tummy. Now breathe in deeply. You will feel your chest and your tummy get bigger as the air goes into your lungs. When the diaphragm contracts (gets tighter) it pushes some of the organs in your tummy down so that there is more space in your chest.

- When you inhale, your diaphragm contracts and moves down, making  more space in your chest. Air rushes in to fill this space, and you  inhale. When you exhale, your diaphrag … m relaxes and moves up,  squeezing the carbon dioxide out of your body. 46 people found this useful.

Intercostal retractions Considerations. The wall of your chest is flexible. This helps you breathe normally. Stiff tissue called cartilage attaches your ribs to the breast bone (sternum). The intercostal muscles are the muscles between the ribs. During breathing, these muscles normally tighten and pull the rib cage up.

- Your diaphragm is the muscle just below your lungs. It marks the boundary between your chest and abdomen. The diaphragm regulates breathing. When your diaphragm contracts, your lungs take in oxygen. When your diaphragm relaxes, your lungs release carbon dioxide. The diaphragm contracting out of rhythm causes hiccups. Each spasm of the diaphragm makes the larynx and vocal cords close suddenly. This results in a sudden rush of air into the lungs. Your body reacts with a gasp or chirp, creating the sound characteristic of hiccups. Singultus is the medical term for hiccups.

Muscles of respiration The diaphragm is the major muscle responsible for breathing. It is a thin, dome-shaped muscle that separates the abdominal cavity from the thoracic cavity. During inhalation, the diaphragm contracts, so that it's centre moves caudally (downward) and its edges move rostrally (upward).

What is the relationship between the intercostal muscles, Diaphragm and the lungs? Report Abuse. respiration holds the relationship During inhalation:The diaphragm becomes flat,the intercostal muscles move upwards and outwards,the lungs is inflamed and pressure decreases,as a result air rushes in to equalize the pressure.hen it contracts, it creates a negative pressure in the upper chest cavity, which expands the lungs, drawing air in. When the diaphram relaxes, you exhale normally. There are two kinds of intercostal muscles; external and internal.

Intercostal Muscles The intercostal muscles contract during inhalation or deep inspiration to support breathing. The external intercostal muscles contract and elevate the ribs during inspiration while the internal and subcostal (innermost) muscles lower your ribs during forced exhalation.here are two types of intercostal muscles: the internal and the external intercostal muscles. These muscles have blood vessels and nerves, which are also found in the intercostal space between ribs.

Stretching Intercostal Muscles When you breathe, your rib cage must be able to expand to accommodate the movement of your lungs. If your rib cage is tight, the amount of air taken in by your lungs is reduced. Poor posture can lead to tight intercostal muscles.

- The lungs rely on surrounding muscles to make them expand and contract. Muscles between the ribs pull the rib cage up and out, making the chest expand and drawing air in, or relax to squeeze the lungs and force air out as the rib cage falls down and in.

- When the muscles of the chest and diaphragm contract they expand the chest, causing the lungs to inflate. Like a balloon, the lungs stretch as they inflate. When you exhale, the muscles relax, and like a balloon that's been released the lungs spring back.ut if the air escapes from the lung and into the chest around the lung, the lung can collapse inside the chest. This can occur from the bursting of a weak spot of the lung, either from another medical condition, infection, or cancer. Or it could be caused by a puncture of the lung such as from a fractured rib.

What is the function of the ribs and diaphagram in the breathing process? Best Answer: Diaphragm: Expands downwards into the abdominal cavity to allow for the lungs to expand as we inhale. As the diaphragm contracts the air is expelled from the lungs. Ribs: The ribs protect the lungs and expand as you inhale to fascillitate space for the lungs to expand like the diaphragm.The ribs then contract expelling the air in the lungs.Altogether now: The diaphragm relaxes and expands downward into the abdominal cavity as the ribs relax to also expand for an increase in air space for the lungs to take in O2.ibs: The ribs protect the lungs and expand as you inhale to fascillitate space for the lungs to expand like the diaphragm. The ribs then contract expelling the air in the lungs.

Diaphragm During exhalation, the rib cage drops to its resting position while the diaphragm relaxes and elevates to its dome-shaped position in the thorax. Air within the lungs is forced out of the body as the size of the thoracic cavity decreases.

How Your Lungs Work When you inhale, the diaphragm and intercostal muscles (those are the muscles between your ribs) contract and expand the chest cavity. This expansion lowers the pressure in the chest cavity below the outside air pressure. Air then flows in through the airways (from high pressure to low pressure) and inflates the lungs. When you exhale, the diaphragm and intercostal muscles relax and the chest cavity gets smaller. The decrease in volume of the cavity increases the pressure in the chest cavity above the outside air pressure. Air from the lungs (high pressure) then flows out of the airways to the outside air (low pressure).

- No. The diaphragm is a muscle below the lungs that aids in drawing in air to the lungs more completely when you take a deep breath. A strong diaphragm also aids in breath cont … rol, especially in athletes and singers. Deep breathing is good for everybody, and should be practiced for optimal lung expansion.aking the world better, one answer at a time. when the diaphragm contracts down it flatten the thoracic cavity floor thus expanding the lungs in a inferior direction.

Muscles of the Chest and Upper Back Small muscles running between the ribs, known as the external intercostal muscles, lift the ribs during deep breathing to further expand the chest and lungs and provide even more air to the body. During exhalation, the diaphragm relaxes to decrease the volume of the thoracic cavity, forcing air out of the lungs.
