12. Blood System Overview  Blood circulates through blood vessels to:  transport oxygen, nutrients and hormones to body cells  carry away waste  Plasma — liquid portion of the blood

13. Blood System Overview  Cellular components suspended in the plasma:  erythrocytes — red blood cells  leukocytes — white blood cells  platelets — cell fragments essential for blood clotting  Serum: portion of the plasma that remains after the clotting process (continued)

14. Components of the Blood

15. Lymphatic System Overview  Protects the body by filtering microorganisms and foreign particles  Maintains the body’s internal fluid environment  Responsible for carrying fats away from digestive organs

16. Lymphatic System

17. Lymph Organs  thymus  primary gland of the lymphatic system  produces T lymphocytes to help immune response  spleen  located between stomach and diaphragm  filters out aging blood cells  removes cellular debris

18. Lymph Structures  lymph  fluid that is circulated through lymph vessels  lymph capillaries  draw lymph from tissues to lymph vessels  lymph vessels  circulate lymph to the lymph nodes

19. Lymph Structures  lymph nodes  oval structures that filter lymph  located in the cervical, axillary and inguinal regions  lymph ducts  collecting channels that carry lymph from the lymph nodes to the veins (continued)

20. Immunity  Process of disease protection induced by exposure to an antigen  antigen — substance that, when introduced into the body causes formation of antibodies against it  antibody — substance produced by the body that destroys or inactivates an antigen

21. Types of Immunity  Active immunity  Protects the body against a future infection as a result of natural antibodies developed after an infection  artificial antibodies — after administration of a vaccine  Passive immunity  conveyed naturally through the placenta to a fetus  conveyed artificially by injection of a serum containing antibodies
