What is the primary vein draining the right adrenal gland?

Superior vena cava
Inferior vena cava
Left renal vein
Renal vein

The correct answer is: Inferior vena cava

The primary vein that drains the right adrenal gland is the inferior vena cava. This is because the right adrenal gland is situated just above the kidney and has a direct venous connection to the inferior vena cava, which receives blood from lower body structures. The inferior vena cava collects venous blood from the lower limbs, pelvis, and abdominal organs, including the right adrenal gland, facilitating efficient drainage. In contrast, the left adrenal gland drains into the left renal vein, which then connects to the inferior vena cava, establishing a more indirect route for the left side. Understanding the vascular anatomy surrounding the adrenal glands is crucial for surgical procedures and for diagnosing conditions related to adrenal disorders, as the venous drainage can significantly impact surgical approaches or management of adrenal tumors.
