Study Notes
Blood Vessels in the Torso and Head
- The ascending aorta arises from the left ventricle and arches upwards.
- Three important vessels branch off the aortic arch:
- Brachiocephalic artery (right)
- Left common carotid artery
- Left subclavian artery
- The brachiocephalic artery branches into the right common carotid and right subclavian arteries.
- The left common carotid artery splits into the internal carotid artery (supplies the Circle of Willis) and external carotid artery (supplies external structures).
- The external carotid artery branches into:
- Facial artery (supplies the face)
- Superficial temporal artery (supplies the muscles of the skull)
- External occipital artery (supplies the muscles of the posterior skull)
Blood Vessels in the Thorax
- The pulmonary trunk (from the right ventricle) branches into the right and left pulmonary arteries, which supply the lungs.
- The pulmonary veins return oxygenated blood to the left atrium.
- The descending thoracic aorta gives off:
- Left posterior intercostal arteries (supply the intercostal muscles)
- Internal thoracic (or mammary) artery (supplies the breast tissue)
- Left anterior intercostal artery (supplies the intercostal muscles)
Blood Vessels in the Abdominal Cavity
- The descending thoracic aorta becomes the abdominal aorta once it crosses the diaphragm.
- The abdominal aorta gives off:
- Inferior phrenic artery (supplies the diaphragm)
- Right and left suprarenal (or adrenal) arteries (supply the adrenal glands)
- Celiac trunk (supplies the stomach, liver, and spleen)
- Left gastric artery (supplies the stomach)
- Common hepatic artery (supplies the liver)
- Splenic artery (supplies the spleen)
- Superior mesenteric artery (supplies the small intestine and part of the large intestine)
- Right and left renal arteries (supply the kidneys)
- Right and left gonadal arteries (supply the testes or ovaries)
- Inferior mesenteric artery (supplies the rest of the large intestine)
- Right and left common iliac arteries (supply the lower limbs)
Blood Vessels in the Lower Limbs
- The right and left common iliac arteries branch into the internal iliac artery and external iliac artery.
- The internal iliac artery gives off:
- Superior gluteal artery (supplies the gluteal muscles)
- Inferior gluteal artery (supplies the gluteal muscles)
- Internal pudendal artery (supplies the external genitalia and perineum)
- Obturator artery (supplies the obturator foramen)
- The external iliac artery becomes the femoral artery, which gives off:
- Lateral circumflex femoral artery
- Medial circumflex femoral artery
- Deep femoral artery (supplies the deep muscle tissue of the thigh)
Blood Vessels in the Abdominal Organs
- The liver receives blood from the right and left hepatic arteries.
- The transverse colon and ileum receive blood from the intestinal arteries, which branch off the superior mesenteric artery.
- The intestinal arteries supply the small intestine, including the jejunum, ileum, and part of the duodenum.### Intestinal Arteries
- The superior mesenteric artery has several branches that supply different parts of the intestine:
- Right colic arteries (310, 311, 312) supply the ascending colon
- Ileocecal artery (313) supplies the cecum and appendix
- Middle colic artery supplies the transverse colon
Inferior Mesenteric Artery
- The inferior mesenteric artery branches into:
- Left colic artery, which supplies the descending colon
- Sigmoid arteries, which supply the sigmoid colon
- Superior rectal artery, which supplies the rectum
Other Arteries
- Common hepatic artery branches into:
- Proper hepatic artery, which supplies the liver
- Gastroduodenal artery, which supplies the stomach and duodenum
- Gastroduodenal artery further branches into:
- Right gastroepiploic artery
- Superior pancreaticoduodenal artery
- Inferior pancreaticoduodenal artery
Additional Arteries
- Left gastric artery (297) supplies the stomach
- Splenic artery (294) supplies the spleen
Blood Vessels in the Torso and Head
- The ascending aorta arises from the left ventricle and arches upwards.
- Three main vessels branch off the aortic arch: brachiocephalic artery, left common carotid artery, and left subclavian artery.
- The brachiocephalic artery branches into the right common carotid and right subclavian arteries.
- The left common carotid artery splits into the internal carotid artery and external carotid artery.
- The external carotid artery branches into the facial artery, superficial temporal artery, and external occipital artery.

Blood Vessels in the Abdominal Cavity
- The descending thoracic aorta becomes the abdominal aorta once it crosses the diaphragm.
- The abdominal aorta gives off several branches, including the inferior phrenic artery, right and left suprarenal arteries, and celiac trunk.
- The celiac trunk branches into the left gastric artery, common hepatic artery, and splenic artery.
Blood Vessels in the Lower Limbs
- The common iliac arteries branch into the internal iliac artery and external iliac artery.
- The internal iliac artery gives off several branches, including the superior gluteal artery and inferior gluteal artery.
- The external iliac artery becomes the femoral artery, which gives off several branches, including the lateral circumflex femoral artery and deep femoral artery.

Other Arteries
- The common hepatic artery branches into the proper hepatic artery and gastroduodenal artery.
- The gastroduodenal artery further branches into the right gastroepiploic artery, superior pancreaticoduodenal artery, and inferior pancreaticoduodenal artery.
Additional Arteries
- The left gastric artery supplies the stomach.
- The splenic artery supplies the spleen.
