Where does the external iliac vein drain?
External Iliac Vein The external iliac vein is a continuation of the femoral vein (the major vessel draining the lower limb), arising when the femoral vein crosses underneath the inguinal ligament. It ascends along the medial aspect of the external iliac artery, before joining with the internal iliac vein to form the common iliac vein.

The internal iliac vein receives the middle rectal, obturator, lateral sacral, inferior gluteal, and superior gluteal veins as tributaries. The obturator vein enters the pelvis by way of the obturator foramen, where it takes a posterosuperior route along the lateral pelvic wall, deep to its artery.
What does the external iliac vein supply blood to?
The external iliac artery provides the main blood supply to the legs. It passes down along the brim of the pelvis and gives off two large branches - the "inferior epigastric artery" and a "deep circumflex artery." These vessels supply blood to the muscles and skin in the lower abdominal wall.
Where is the external iliac vein?

The internal iliac vein drains blood from the visceral organs in the pelvic region. The external iliac connects to the femoral veins.
What arises from the external iliac artery?
Although they do not directly supply a muscle or tissue, the external iliac arteries give rise to two arterial branches that perfuse surrounding muscles: the inferior epigastric artery and the deep circumflex iliac artery.

D. The pulmonary artery brings oxygen and nutrients to the lung tissue.
Which part of the heart is closer to the heart?
A. Arteries are closer to the heart and its force.

Which veins are in the external iliac vein?
During its short course, the external iliac vein receives the inferior epigastric and deep circumflex iliac veins.
Which vein drains into the common iliac?
With the exception of the iliolumbar vein (which drains into the common iliac), the tributaries of the internal iliac vein correspond with the branches of the internal iliac artery. It receives venous blood from the: Superior and inferior gluteal veins – drains the buttock and upper thigh.
What is the name of the vein that drains blood from the heart?
The veins of the pelvis drain deoxygenated blood and return it to the heart. There are three major vessels involved in the venous drainage of the pelvis – the external iliac vein, internal iliac vein and common iliac vein (these correspond the major pelvic arteries).
What is the venous drainage of the pelvis?
There are three major vessels involved in the venous drainage of the pelvis – the external iliac vein, internal iliac vein and common iliac vein (these correspond the major pelvic arteries).
What drains the female reproductive organs?
Uterine and vaginal veins - drain the female reproductive organs via the vaginal and uterine venous plexuses. Common Iliac Vein. The common iliac vein is formed at the upper margin of the pubic symphysis by the union of the external and internal iliac veins. It receives two additional tributaries:
What is the middle sacral vein?
Middle sacral veins - drain part of the sacrum. The left and right common iliac veins combine at L5 to become the inferior vena cava, which empties into the inferior aspect of the right atrium. [start-clinical] Clinical Relevance - Pelvic Congestion Syndrome.
What is used to embolise veins?
Using a venous catheter a guide wire is fed through, a contrast dye is used and affected vessels are embolised (blocked) with various substances, such as metal coils. Due to the rich venous anastomoses in the pelvis, one smaller vein can be tied off without compromising venous return.
What is the iliac artery?
Clinical Significance. The external iliac arteries are two major blood vessels in the pelvis and are a continuation of the aorta and common iliac arteries. Blood is pumped from the heart to the rest of the body via the aorta, the largest artery in the body. In the abdomen, the aorta splits into the right and left common iliac arteries.
Which artery supplies blood to the anterior abdominal wall?
The inferior epigastric artery arises just above the inguinal ligament and supplies blood to the anterior abdominal wall. The deep iliac circumflex artery also arises just above the inguinal ligament and helps supply the iliacus muscle and the deep and lateral abdominal wall.
What is the condition that causes scar tissue in the walls of the external iliac arteries?
Elite, competitive athletes such as cyclists, runners, and speed skaters are at increased risk for a condition called external iliac artery endofibrosis. The exact cause of this condition is not known for sure, but it results in the deposition of scar tissue in the walls of the external iliac arteries, causing narrowing of the vessels.
What is the aorta split into?
In the lower abdomen, at about the level of the fourth lumbar vertebra, the aorta splits into two smaller arteries called the common iliac arteries. Each common iliac artery splits again into the external iliac artery and the internal iliac artery. Each internal iliac artery has many branches which supply the deep organs and other structures ...
What arteries are in the aorta?
In the abdomen, the aorta splits into the right and left common iliac arteries. At the pelvic brim, each common iliac artery splits into the internal and external iliac arteries. Each external iliac artery courses downward and laterally, turning into the femoral artery, which supplies each leg. MedicalRF.com / Getty Images.
Where is the most common site of an aneurysm?

Which artery runs down the border of the psoas muscle?
Each external iliac artery courses downward and laterally along the border of the psoas muscles. Once they pass below the inguinal ligaments (paired ligaments which extend obliquely across the groin), they become the femoral arteries, which supply each leg. Along their course, each external iliac artery gives off several small branches to the neighboring psoas muscle and two large branches: the inferior epigastric artery and the deep iliac circumflex artery.
Which vein is posterior to the common iliac artery?
Right obturator nerve is in its posterior relation. The left common iliac vein runs medial to the left common iliac artery then also becomes posterior. Left common iliac is longer and more oblique. This vein has attachment of sigmoid mesocolon and superior rectal vessel in its anterior relations.
