Answer:

The diaphragm has three openings: Aortic Hiatus - the most dorsal opening, contains the aorta, azygous vein and thoracic duct.

Oesophageal Hiatus - contains the oesophagus, dorsal and ventral vagal trunks.

Caval Foramen - lies within the central tendinous region of the diaphragm and contains the caudal vena cava.
