Upon opening the anterior abdominal wall, you will be faced with a large sheet of adipose tissue, an apron-like structure of mesentery called the greater omentum. This tissue holds energy in the form of lipids stored in fat cells, as well as housing immune cells within the connective tissue. Once you displace the greater omentum you will see the sinuous nature of the digestive tract, which is a natural result of the developmental process of elongation, physiological herniation, and retraction as the gut tube forms and the anterior abdominal wall closes.
