The 1st branch from the CHA (common hepatic artery) is:
Gastroduodenal artery (GDA), common hepatic artery divides into PHA and GDA
-------Arise from the anterior aspect of the abdominal aorta inferior to the renal arteries to Supply the gonads, not seen by us.
Gonadal arteries
35. ---------Arise from the anterior aspect of the abdominal aorta inferior to the renal arteries to Supply the gonads, not seen by us.
Gonadal arteries
---is the last major branch of the abdominal aorta prior to the aortic bifurcation, arises from the anterior aorta
Inferior mesenteric artery (IMA)
-------------- arise from the anterior aspect of the abdominal aorta branching into the right and left inferior phrenic arteries artery just below the diaphragm.
Inferior phrenic artery
Proper hepatic artery (PHA) supply the:
Liver (it is part of the portal triad)
Right renal artery is longer than left renal artery. T/F, Why?
Longer, it has to go pass the IVC in order to reach the right kidney.
----- Located inferior to the gonadal arteries and superior to the inferior mesenteric artery, supplies the abdominal wall and spinal cord.
Lumbar arteries
------------Arise from the posterior lateral aspects of the abdominal aorta, 1.0 - 1.5 cm inferior to the superior mesenteric artery and supply the kidneys.
