Which best describes the diaphragm?
The diaphragm is a thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest. It contracts and flattens when you inhale. This creates a vacuum effect that pulls air into the lungs. When you exhale, the diaphragm relaxes and the air is pushed out of lungs.
What is the role of diaphragm and ribs in respiration?
Complete answer: The diaphragm relaxes during natural exhalation, helping the air to pass out as the lungs deflate. Like the diaphragm, the ribs shield the lungs and expand while we inhale to promote room for the lungs to expand. Then the ribs contract, expelling the air from the lungs.

Where does diaphragm attach?
Origin and insertion. The diaphragm is a musculotendinous structure with a peripheral attachment to a number of bony structures. It is attached anteriorly to the xiphoid process and costal margin, laterally to the 11th and 12th ribs, and posteriorly to the lumbar vertebrae.
Does the diaphragm control breathing?
The lungs have no skeletal muscles of their own. The work of breathing is done by the diaphragm, the muscles between the ribs (intercostal muscles), the muscles in the neck, and the abdominal muscles.
What is ribs and diaphragm?
Ribs muscles: The ribs help in the expansion and contraction of the thoracic cavity and also protect the lungs and heart. When the diaphragm expands or contracts, the thoracic (chest) cavity expands or contracts, alternately pulling in the air (inhalation) or expelling it (exhalation).
Where is the diaphragm located?
The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges.
