Table 2012 Major Tributaries of the Inferior Vena Cava

The inferior vena cava (IVC) is formed by the union of the right and left common iliac veins at the level of vertebra L5. It is retroperitoneal and lies immediately to the right of the aorta. Its diameter of 3.5 cm is the largest of any vessel in the body. As it ascends the abdominal cavity, the IVC picks up blood from numerous tributaries in the order listed here (fig. 20.36):

1. Some lumbar veins empty into the IVC as well as into the ascending lumbar veins described in table 20.11.

2. The gonadal veins (ovarian veins in the female and testicular veins in the male) drain the gonads. The right gonadal vein empties directly into the IVC, whereas the left gonadal vein empties into the left renal vein.

3. The renal veins drain the kidneys into the IVC. The left renal vein also receives blood from the left gonadal and left suprarenal veins.

4. The suprarenal veins drain the adrenal (suprarenal) glands. The right suprarenal empties directly into the IVC, and the left suprarenal empties into the renal vein.

5. The hepatic veins drain the liver; they extend a short distance from its superior surface to the IVC.

6. The inferior phrenic veins drain the inferior aspect of the diaphragm.

After receiving these inputs, the IVC penetrates the diaphragm and enters the right atrium from below. It does not receive any thoracic drainage.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
