List of veins in the human body
The human body contains a vast network of veins that are crucial for returning deoxygenated blood back to the heart after oxygen and nutrients have been delivered to tissues by the arteries. This article provides a comprehensive list of the major veins in the human body, categorized by the regions they serve and their primary functions.
Head and Neck[edit | edit source]
- Internal jugular vein: Drains blood from the brain, the superficial parts of the face, and the neck.
- External jugular vein: Drains the outer parts of the face and the scalp.
- Vertebral vein: Drains the posterior part of the head and the neck, running alongside the vertebral artery.
- Facial vein: Drains the facial structures, anastomosing with the internal and external jugular veins.
Upper Limbs[edit | edit source]
- Brachial vein: Accompanies the brachial artery and drains blood from the lower arm and hand.
- Cephalic vein: Runs along the lateral side of the arm and drains into the axillary vein.
- Basilic vein: Located on the medial side of the arm, it drains into the brachial vein.
- Median cubital vein: An important site for venipuncture, it connects the cephalic and basilic veins.
Thorax[edit | edit source]
- Superior vena cava: A large diameter vein that receives blood from the upper body and empties into the right atrium of the heart.
- Inferior vena cava: Carries blood from the lower body to the right atrium of the heart.
- Azygos vein: Drains the thoracic wall and upper lumbar region into the superior vena cava.

Abdomen[edit | edit source]
- Hepatic veins: Drain deoxygenated blood from the liver into the inferior vena cava.
- Renal veins: Drain the kidneys into the inferior vena cava.
- Portal vein: Carries blood from the gastrointestinal tract and spleen to the liver, rich in nutrients.
Pelvis and Lower Limbs[edit | edit source]
- Femoral vein: The major vein of the thigh, draining into the external iliac vein.
- Great saphenous vein: The longest vein in the body, running along the length of the lower limb.
