Human anatomy, including structure and development and practical considerations . ard, so that the loop of intes-tine, which the duodenum originally formed, must be considered as having fallen I750 HUMAN ANATOMY. over onto the riy^ht side aj4;ainst the rii^lu of the si)in:il column, to the peritonealcoverini; of whicli it lias grown with the transformation into connective tissue of therii(ht serous co\erini; of its mesentery. The second or descending portion of theduodenum lies against the right of the column under the permanent ])arietal peri-toneum, derived from the mesocolon, as is shown later. The great difficulty of un-derstanding the lesser cavity is that in man the duodenum rises to so near the liverthat the entrance to the vestibule at the foramen of Winslow is very small. If. as inmany animals, these parts were more distant, it would be evident that this is a pouch- FiG. 1475.

The splenic artery, in the adult condition, lies entirely behind the perma-nent peritoneum to near the hilum of the spleen, where the mesogastrium is nolonger attached to the wall. It then sends its terminal branches to the spleen, thegastro-epiploica sinistra to the greater curvature of the stomach, and the vasa breviato the fundus.
