Right - Directly into IVC
Left - Left renal vein
Arterial supply to ovaries
Ovarian arteries (direct branches of abdominal aorta @ L2)
Lymphatic drainage of uterus
Ovaries/uterine tubes - aortic nodes at root of ovarian artery (L2)
Body of uterus - external iliac nodes via broad ligament
Cervix - Internal iliac then superficial nodes
Fundus/round ligament - superficial inguinal nodes via round ligament

vaginal artery

internal pudendal
Innervation of external anal sphincter

it highlights the end of the internal part of digestive tract
What is the white line?
The anocutaneous line

What is the arterial supply to the wall of the rectum?
Superior rectal (IMA)
Middle rectal (internal iliac)
Inferior rectal (Internal pudendal)
Arterial supply to anal canal
Inferior rectal arteries supply the wall but superior rectal arteries are within anal columns
What is the innervation and lymphatic drainage above pectinate line?
Visceral motor
Internal iliac nodes
What is the innervation and lymphatic drainage below pectinate line?
Somatic motor and sensory
Superficial inguinal nodes
