*The position of the jejunum is variable between species as it lies in that part of the abdomen not occupied by other viscera.  

*The position of the jejunum is variable between species as it lies in that part of the abdomen not occupied by other viscera.  

*In the dog, it lies roughly symmetrically about the midline. It contacts the [[Liver - Anatomy & Physiology|liver]], stomach and [[Spleen - Anatomy & Physiology|spleen]] cranially and [[Bladder - Anatomy & Physiology|urinary bladder]] ventrally. It lies on the deep sheet of the greater omentum.  

 

*In the ox, it is pushed entirely to the right side of the abdomen by the [[The Rumen|rumen]] which is on the left. Coils of the jejunum usually lie within the supraomental recess; although this can vary between individuals depending on fullness of the rumen and size of the uterus.

*In the horse, the coils of jejunum ane confined to the left dorsal part of the abdomen. It is restricted to this position by the large caecum on the right, and ascending colon ventrally on both sides.

*Jejunumo lies in the caudoventral aspect of the abdominal cavity, mainly to the right of the midline.

**This is due to the presence of the ascending colon on the left.
