  1. Major Vessels of the Body

  2. Arteries Thoracic Aorta—aorta above diaphragm Abdominal aorta—below diaphragm down to groin area Veins Superior Vena Cava (SVC)—vein leading back to the heart from the upper body Inferior Vena Cava (IVC)—vein leading back to the heart fro the lower body Largest Veins and Arteries

  3. Major branches of the Abdominal Aorta • Celiac artery—gives rise to the gastirc splenic and hepatic arteries • Phrenic arteries—paired arteries that supply blood to the diaphragm • Superior mesenteric artery—branches to many parts of the intestinal track. • Suprarenal arteries—paired arteries that supply blood to the adrenal glands. • Renal arteries—pass from the aorta into the kidneys • Gonadal arteries—paired arteries that supply blood to the gonads • Inferior mesenteric artery—lead blood to the lower portion of the colon and rectum • Lumbar arteries—3-4 pairs of arteries in the lumbar region that supply blood to the muscles of the skin • Middle sacral artery—small single vessel that extend from aorta to supply blood to the saccrum and coccyx.

  4. Arteries of the Head, Neck and Brain • External Carotid artery—course upward on the side of the head, giving off brances to structures in the neck, face, jaw, scalp and base of the skull. • Internal Carotid artery—follows a deep course upward along the pharynx to the base of the skull and enters the brain

  5. Arteries to the Shoulder and Upper Limb • Subclavian Artery • Axillary artery • Brachial artery • Ulnar artery • Radial artery

  6. Arteries to the Thoracic & Abdominal Walls • Internal thoracic artery

  7. Arteries to the Pelvis and Lower Limb • Common iliac arteries • Internal iliac artery • External iliac artery • Femoral artery • Popliteal artery • Anterior tibial artery • Posterior tibial artery

  8. Veins from the Head, Neck and Brain • External jugular • Internal jugular veins • Brachiocephalic veins These vessels merge into the superior vena cava

  9. Veins from the Upper Limb and Shoulder The deep veins parallel the arteries and are given similar names: • Radial vein • Ulnar vein • Bracial vein • Axillary vein • Subclavian vein

  10. Veins from the Abdominal Viscera • Hepatic portal vein • Gastric vein • Superior mesenteric vein • Splenic vein • Hepatic veins • Inferior mesenteric vein

  11. Veins from the Lower Limbs & Pelvis • Popliteal vein • Femoral vein • Exteranl iliac vein • Small saphenous vein • Great saphenous vein • Internal iliac vein • Common iliac veins
