Detailed explanation-1: -The diaphragm is a thin dome-shaped muscle which separates the thoracic cavity (lungs and heart) from the abdominal cavity (intestines, stomach, liver, etc.). It is involved in respiration, drawing downward in the chest on inhalation, and pushing upward in exhalation.

Detailed explanation-2: -The diaphragm is a large muscle that separates the chest, and the organs in it, from the abdomen and the body organs located there. This muscle, also called the thoracic diaphragm, plays an important role in breathing as its alternating movement helps you to inhale and exhale.

Detailed explanation-3: -The diaphragm is the muscular sheet that forms a partition between the chest cavity and the abdominal cavity. Its movement during inhalation and exhalation regulates the pressure of the chest cavity which enables the movement of air in or out of the lungs.

Detailed explanation-4: -The diaphragm (DYE-uh-fram) is a muscle between the chest and the abdomen that allows the body to move air in and out of the respiratory system. When you breathe in (inhalation), the diaphragm moves down toward the abdomen, and the rib muscles pull the ribs upward and outward.

Detailed explanation-5: -A large, muscular sheet called diaphragm forms the floor of the chest cavity.
