The normal pattern of venous and lymphatic drainage of the superficial tissues of the anterior abdominal wall is arranged around a horizontal plane. above that plane, drainage is in a cranial direction; below the plane drainage is in a caudal direction. this reference plane corresponds to: a. transpyloric planeb. level of anterior superior iliac spinesc. transtubercular lined. level of arcuate linee. level of umbilicus

E. Level of umbilicus

Explanation:

Level of umbilicus

The umbilicus region is a major area for the lymphatic and venous drainage of the wall of the abdominal region .

In the above region of the umbilicus , the The venous blood drains into the superiors epigastric vein and the lymphatics drain into the axillary lymph nodes .

In the region below the umbilicus , the while the venous venous blood drains into the inferior epigastric vein and the external iliac vein and the lymphatics drains into the superficial inguinal lymph nodes .

the ileocecal valve (also called bauhin valve), which limits the rate of food passage into the cecum and may prevent material from returning to the small intestine.
