Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which blood vessel does the hepatic vein lead into?
A
vena cava
B
pulmonary vein
C
aorta
D
pulmonary artery
Explanation: 

Detailed explanation-1: -Blood leaves the liver through the hepatic veins. This blood is a mixture of blood from the hepatic artery and from the portal vein . The hepatic veins carry blood to the inferior vena cava-the largest vein in the body-which then carries blood from the abdomen and lower parts of the body to the right side of the heart.

Detailed explanation-2: -The hepatic portal vein The portal vein thus drains blood from most of the gastrointestinal tract. Blood then traverses the liver in the hepatic sinusoids and empties into the central veins through which it reaches the inferior vena cava.

Detailed explanation-3: -In human anatomy, the hepatic veins are the veins that drain venous blood from the liver into the inferior vena cava (as opposed to the hepatic portal vein which conveys blood from the gastrointestinal organs to the liver ).

Detailed explanation-4: -Blood from the abdominal viscera travels into the portal vein and enters the IVC via the hepatic veins after traversing the liver and its sinusoids. Venous blood from the abdominal wall reaches the IVC through lumbar veins.
