11. Cardiovascular Structure Blood Vessels Arteries: blood away from the heart Capillaries: between arteries and veins Veins: blood to heart

12. The Lymphatic System Lymph – fluid that fills the spaces around body cells Lymphocytes – cells that provide immunity (B & T cells)

13. B cells –Multiply into plasma and memory cells T cells –Helper –Killer Lymphocytes

14. Lymphatic Structure Vessels collect lymph Filtered by nodes with white blood cells Ducts empty lymph into veins

20. Cardiovascular Problems Varicose Veins –Valves in veins do not close tightly –Prevented by physical activity

21. Cardiovascular Problems Anemia –Ability of the blood to carry oxygen is reduced –Caused by iron deficiency

22. Cardiovascular Problems Leukemia –A cancer in which there are excessively and abnormal white blood cells

23. Cardiovascular Problems Hemophilia –Protein (clotting factors) in blood missing

24. Lymphatic Problems Immune Deficiency –A lack of immune system

25. Lymphatic Problems Hodgkin’s Disease –(Hodgkin’s Lymphoma) a type of cancer of lymph tissue found in the nodes and spleen
