Detailed explanation-1: -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.

Detailed explanation-2: -The diaphragm is a muscle that helps you inhale and exhale (breathe in and out). This thin, dome-shaped muscle sits below your lungs and heart. It’s attached to your sternum (a bone in the middle of your chest), the bottom of your rib cage and your spine.

Detailed explanation-3: -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.

Detailed explanation-4: -Your lower esophagus, stomach, intestines, liver, and kidneys are below the diaphragm, in your abdominal cavity. The left and right phrenic nerves send signals to control the diaphragm, which receives its blood supply primarily from the inferior phrenic arteries.

Detailed explanation-5: -They sit to the left and right of the heart, within a space called the thoracic cavity. The cavity is protected by the rib cage. A sheet of muscle called the diaphragm serves other parts of the respiratory system, such as the trachea, or windpipe, and bronchi, conduct air to the lungs.
