Major Veins draining Thorax Abdomen and Pelvis Veins drain.pdf

Major Veins draining Thorax, Abdomen, and Pelvis Veins draining the Abdomen Inferior vena cava
- collects blood from the common iliac veins (Left + Right) Hepatic veins (L,R) Gonadal veins (L,R)
Renal veins (L,R) Hepatic Portal Vein and Hepatic Portal Circulation - Portal vein circulation =
artery capillary bed PORTAL VEIN capillary bed vein - A special form of circulation: Veins of the
abdomen, Gl tract, and pelvis drain nutrient-rich, deoxygenated blood into the hepatic portal vein
for delivery to the capillaries of the liver for nutrient-processing and detoxification. The hepatic
portal system is formed where the following veins merge: 1. Splenic vein and 2. Superior
mesenteric vein - Branches draining into hepatic portal vein that delivers oxygen-poor, nutrient-rich
blood to the liver. a. Gastric veins b. Splenic vein Drains blood from the: a. Inferior mesenteric vein
c. Superior mesenteric vein Veins draining the pelvis and lower extremities Common iliac veins (L,
R) (from inferior vena cava) - branches to form: a. Internal iliac veins (L,R) b. External iliac veins (L
,R) a. - branches into femoral veins and great saphenous vein External iliac veins (from common
iliac) - branches to form: Femoral veins (L,R)Superficial vs deep veins - Veins are categorized into
two different types: Superficial and Deep Deep veins commonly travel with arteries (deep and
protected; function as skeletal muscle pump) Superficial veins are visible underneath the skin
(depending on subQ fat and underlying connective tissue) and eventually drain into the major
veins of the body. - Also, perforating vein anastomoses connect deep veins to superficial veins. -
Listed below are the primary deep veins of the body. It is important to remember that deep veins
commonly travel with their corresponding major artery. Veins of the Thoracic Cavity and Upper
Limbs The vena cavae are continuous with the right atrium: - Superior vena cava drains the head,
neck, upper limbs, and thorax - Inferior vena cava drains the lower limbs, pelvis, abdominal cavity
and viscera Major Veins draining head and neck: a. Brachiocephalic veins (L,R) - Formed by
junction of the internal jugular and subclavian b. External jugular veins (L,R) c. Internal jugular
veins (L,R) Subclavian vein (L,R) branches drain the upper limb extremities Arm a. Axillary veins (
L,R) b. Brachial veins (L,R) Forearm (veins drain blood from the digits and the hand) a. Uinar
veins (L,R) b. Radial veins (L,R).
