coeliaca

Coeliaca, also known as the celiac trunk, is the largest branch of the abdominal aorta, the body's main blood vessel. It supplies blood to the abdominal organs, including the stomach, liver, spleen, and pancreas. The coeliaca trunk typically arises from the abdominal aorta just below the diaphragm, and it divides into several smaller branches that distribute blood to these organs.

The coeliaca trunk is an important anatomical landmark in the abdomen. It is often used as a reference point for locating other structures in the abdominal cavity. For example, the coeliac plexus, a network of nerves that innervates the abdominal organs, is located near the coeliaca trunk.

The coeliaca trunk can be affected by various medical conditions, such as coeliac disease, which is an autoimmune disorder that causes inflammation of the small intestine. In this condition, the coeliaca trunk may be enlarged and swollen due to the inflammation.

In summary, the coeliaca trunk is a crucial blood vessel in the abdomen that supplies blood to several important organs. It is an essential anatomical landmark and can be affected by certain medical conditions.
