Anatomy, Abdomen and Pelvis: Arteries

Excerpt

The abdominal arteries arise from the abdominal aorta and are comprised of three groups of arteries: unpaired visceral arteries, paired visceral arteries, and parietal arteries. The unpaired visceral arteries supply the gastrointestinal (GI) tract, spleen, pancreas, gallbladder, and liver and are made up of the celiac trunk, superior mesenteric artery (SMA), and inferior mesenteric artery (IMA). The paired visceral arteries supply the kidneys, adrenal glands, and gonads and are made up of the middle suprarenals, renals, and gonadal branches of the abdominal aorta. The parietal arteries supply the musculoskeletal structures of the abdominal wall and are made up of the inferior phrenic, lumbar, and median sacral branches of the abdominal aorta.
