• A. Renal and gonadal vein
• B. Gonadal and Hepatic
• C. Renal and Hepatic
• D. Renal, gonadal and Hepatic

Answer 1

Answer: (D)

Renal, gonadal and Hepatic

The posterior or inferior vena cava is a large vein that carries deoxygenated blood from the lower and middle part of the body into the right atrium of the heart. It runs posterior or behind the abdominal cavity. Along its way through the abdomen, blood flow from the internal organs joins the inferior vena cava through a series of large veins, including the gonadal, renal, suprarenal, and inferior phrenic nerves. The hepatic veins provides blood from the digestive organs of the abdomen after it has passed through the hepatic portal system in the liver. Blood from the tissues of the lower back, including the spinl cord and muscles of the back, enters the vena cava through the lumbar veins. Many smaller veins also provide blood to the vena cava from the tissues of the abdominal body wall. Upon reaching the heart, the inferior vena cava connects to the right atrium on its posterior side, inferior to the connection of the superior vena cava.

So, the correct option is D.
