1 Cardiovascular System – vessels -Chapter 19 C Arteries – Head & Neck 1. 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 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 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 leave abdominal cavity and become: 20. femoral arteries, serving the muscles of the thigh: hamstrings, quadraceps & adductors

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 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 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 Veins that drain blood from hand, wrist & lower arm: 7. Radial 8. 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 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 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 (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 The 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
