What is the primary role of the diaphragm, a dome-shaped muscle located beneath the lungs?

Explanation

The diaphragm is a dome-shaped muscle located just beneath the lungs that plays a central role in breathing, contracting and flattening downward to help draw air into the lungs during inhalation, and relaxing back into its dome shape to help push air out during exhalation. Along with other muscles between the ribs, the diaphragm’s rhythmic movement is largely automatic and controlled unconsciously, though a person can also consciously control their breathing to some extent. Hiccups occur when the diaphragm involuntarily and repeatedly contracts in a sudden, spasmodic way. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
