Fig. 222.âDiagrams illustrating the development of the mesenteries and omentum in the human embryo. An arrow marks the opening (foramen of Winslow) of the greater omentum. (Redrawn after Hertwig.) As the sacculation of the mesogaster progresses, dorsal and ventral layers become distinguishable. The two-layered sac thus formed grows ventrally and posteriorly between the viscera and the ventral wall of the abdomen as an apron-like membrane, the greater omentum. Much of the original cavity of the omentum is lost through the fusion of dorsal and ventral layers. In the region of the stomach, however, the cavity persists as the bursa omentalis, which opens by the foramen epiploicum into the coelom of the right side. The omentum becomes the seat of deposit of con- siderable fat and serves as a blanket to keep the viscera warm. The Liver The functions of the Hver are diverse. During early ontogenesis, it forms red blood corpuscles. Later in life, it becomes an agent in the eUmination of blood cells. It transforms both sugar and protein into a polysaccharid, glycogen, which it stores in its cells for later use. It also.
