GROSS ANATOMY

Detailed explanation-1: -The diaphragm has many other roles besides respiration. It acts as a barrier between the thoracic and abdominal cavity and prevents herniation of abdominal organs into the chest cavity.

Detailed explanation-2: -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-3: -The diaphragm develops during the third week of embryogenesis. It is formed by transverse and longitudinal folding.

Detailed explanation-4: -Your diaphragm is what separates your thoracic cavity from your abdominal cavity. Several blood vessels, nerves and tissues pass through your diaphragm as they travel between your chest and belly. These include your aorta, esophagus and vagus nerve. Front boundary: The front boundary is your sternum (breastbone).

Detailed explanation-5: -Anatomically, you can define hiatus as an opening, slit, or gap that allows structures to pass. These openings in the diaphragm allow the inferior vena cava, esophagus, vagus nerves, descending aorta, and other structures to pass through.
