 The two layers then embrace the transverse colon, unite, 

 and pass back to the vertebral column, forming the transverse 

 mesocolon. From here the layers separate, the upper one ascend-

 layer descends in front of the duodenum aorta, incloses the small 

 intestine (forming the mesentery proper), is reflected upon the 

 rectum (forming the mesorectum) and the bladder, and ascends 

 upon the anterior abdominal wall to the starting point. 



In the female, from the rectum it envelops the uterus and 

 upper part of the vagina before reaching the bladder.
