Blood supply
The adrenal glands receive their blood from 3 main components:
- This lower phrenic artery has a minor branch called the superior adrenal artery.
- The aorta is the primary origin of the central adrenal artery.
- This renal artery forms the contralateral source of the lower adrenal artery.
The source of the adrenal artery can vary widely. The aorta, axis, and, less frequently, an intercostal artery can all be the origin of the superior adrenal artery. There are frequently numerous arteries that makeup one upper adrenal artery. The lower phrenic, renal, upper mesenteric, or celiac axis are all possible origins of the central adrenal artery lower phrenic artery may also be the source of the lower adrenal artery.
The aspect of the glands affects the vein outflow from either the adrenal glands. The left adrenal vein empties through into the left renal vein because the left adrenal gland was physiologically located further out inferior vena cava. The right adrenal vein empties straight through into the inferior vena cava, which is significantly closer to it. There are frequently differences in adrenal venous drainage, especially just on the left side. According to sources, the lower phrenic vein and the left vaginal and adrenal veins link via veins. Additionally frequent are either left adrenal veins.
Adrenal Gland
The right lobes of the liver and the inferior vena cava are located on the front side of the adrenal gland which would be on right. The right diaphragm crus is attached to the posterior side. The front side of the adrenal gland which would be on left is where the stomach, pancreas, and spleen are located. The left diaphragmatic crus is attached to the posterior aspect.
