  1. Cardiovascular System – vessels -Chapter 19C Arteries – Head & Neck • Brachiocephalic trunk – right only – comes directly off the aortic arch • A. Gives rise to: . 2. common carotid . 3. subclavian .B. Left only - common carotid & subclavian . come directly off aortic arch • Table: 19.5 a&b pg. 726 & 727

  13. 13 Arteries of the abdomen • Visceral organs of the abdominopelvic cavity • At rest these arteries contain half of all the blood in the body • Branch off the Abdominal aorta 13. Celiac trunk – blood to the stomach, . liver, pancreas, spleen table 19.24 a& b pg. 730 & 731

  20. 20 Arteries of the pelvis & legs 17. Common iliacs – bifurcation of distal abdominal aorta Common iliacs split to form . 18. Internal iliacs – pelvic viscera & gluteal . Muscles . 19. External iliacs External iliacs leave abdominal cavity and become: 20. femoral arteries, serving the muscles of the thigh: hamstrings, quadraceps & adductors

  21. 21. Popiteal: creates an anastomosis in the knee region Popliteal artery bifurcates and forms two branches in the lower leg 22. & 23 anterior & posterior tibial arteries Table 19.8 a & b pgs. 734 & 735

  24. 24 Veins – 1. Superior Vena Cava – drains blood from regions superior to the diaphragm 2. L & R brachiocephalics merge to form the superior vena cava Veins draining head and neck Two veins bring blood from the head to the brachiocephalics: 3. Internal jugular 4. Vertebral vein

  25. 25 5. Subclavian vein merges w/ brachiocephalic 6. External jugular brings blood from head to the subclavian vein Table: 19.27 a,b,& c pg. 738 & 739

  29. 29 Veins that drain blood from hand, wrist & lower arm: 7. Radial 8. Ulnar Ulnar and radial merge and drain blood into: 9. brachial vein which turns into the axillary then subclavian vein 10. Median cuboidal – the vein Dr. takes blood from Table 19.11 a & b pgs: 740 & 741

  32. 32 Veins of the abdomen – • Blood drained from the abdominopelvic region enters the inferior vena cava • Veins often follow the paths and share names w/ their arterial counter parts • Veins draining blood from the digestive tract (digested food) all empty into a (12) common hepatic portal vein that goes to the liver to “process” the blood 13 & 14 Superior and inferior mesenteric veins empty into the hepatic portal vein Figure 19.29 pg. 742 & table 19.12 c; pg. 743

  38. 38 Veins of the pelvis & lower limb • Great and small saphenous veins drain the calf & foot • They are superficial and a common site for varicose veins • Used in coronary artery bi-pass surgery The (16.) anterior tibial and (17) posterior tibial also drain the calf and foot. They join, at the knee and form the knee and form the (18.) popliteal vein. The popliteal continues past the knee and forms the (19.) femoral vein, which drains the thigh, and becomes the (20.) external iliac vein

  39. 39The external and (21) internal iliacs join and form the (22) common iliac which drains into the inferior vena cava figure 19.30 a,b & c; page 744
