∙ 12y agoThe diaphragm (dye-uh-fram) muscle contracts during inhalations, and causes your belly to push out. During exhalation, the diaphragm muscles relax and your belly flattens back out.

How are diaphragm and intercostal muscles stimulated?
The diaphragm is stimulated the same way all other muscles are - nerve impulses that originate in the brain (or sometimes the spinal cord). The intercostal muscles expand during inhalation and contract during exhalation in response to the movement of the lungs by the diaphragm.
What happens to the chest during inhalation?
the intercostal muscles contract
Does the rib expand during inhalation or exhalation?
The ribs expand during inhalation. This creates negative pressure on the lungs and draws air into them. During exhalation the rib cage gets smaller, compressing the lungs, in a sense, and forcing air out.
What are abnormal breath sounds heard during inhalation or exhalation called?
Crackles
What is a dome shaped muscle found under the rib cage which assists during inhalation and exhalation?
Diaphragm
Describe the movement of the ribcage and diaphragm during exhalation?
I believe the ribs are there to protect our lungs, heart etc. When we breath in, what we are actually doing is telling our diaphragm to contract, which moves it in a downwards motion. This caused pressure in our lungs to lower which pulls in air.
What is the name of the rib muscles that contribute to breathing?
Ribs are bones, but lungs contribute to breathing and they are a muscle organNo, your Lungs ARE NOT A MUSCLE. Your diaphragm is the main muscle in inhalation, which opens your lungs (works by creating a negative pressure in your lungs i.e. the pressure outside your chest cavity is more than the pressure in your lungs, causing air to enter your lungs).However, during forced inhalation and exhalation your intercostal muscles and rectus abdominus muslces play a part in exhalation (forcing air out). scalenes lift up your rib cage to allow maximum inhalation.
What 2 muscles work together during inhalation?
The diaphragm and the external intercostal muscles.
What happens to animals during respiraton?
Respiration is the exchange of gases such as oxygen and carbon dioxide, not to be confused with ventilation, which is inhalation and exhalation
Which position should the ribs be kept in during inhalation and exhalation?
keep your chest stable, you dont need to raise your chest
What is the muscle that enables respiration to occur?
There are number of muscles which work together during respiration. The major muscles to look at: 1.diaphragm and transversus abdominus, which will enable you to inhale and exhale 2.intercostal Muscles and transversus thoracic, which are responsible for both inhalation and exhalation, but are also maintaining the structure of your lung and your thorax and preventing it from collapsing on itself.
How do the ribs and diaphragm move to aide inspiration?
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.
