(continued)

11. Components of the Blood p277 278

12. Lymphatic System Overview p281
Protects the body by filtering microorganisms and foreign particles
Maintains the body’s internal fluid environment
Responsible for carrying fats away from digestive organs

13. Lymphatic System

14. Lymphatic Organs thymus spleen 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

15. Lymphatic Structures lymph
fluid that is circulated through lymph vessels
lymph capillaries (where have we seen capillary before?)
draw lymph from tissues to lymph vessels
lymph vessels
circulate lymph to the lymph nodes

16. Lymphatic Structures lymph nodes (think nodule)
(continued)
lymph nodes (think nodule)
oval structures that filter lymph
located in the cervical, axillary, and inguinal regions
lymph ducts (think air duct for an air conditioner)
collecting channels that carry lymph from the lymph nodes to the veins

17. 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 (think: generates an immune response)
antibody – substance produced by the body that destroys or inactivates an antigen

18. Types of Immunity Active immunity long lasting
protects the body against a future infection as a result of natural antibodies developed following a natural infection
(artificial antibodies – after administration of a vaccine)

19. Types of Immunity Passive immunity short lasting
(continued)
Passive immunity
short lasting
conveyed naturally through the placenta to a fetus (the mother passes it along to the baby)
conveyed artificially by injection of a serum containing antibodies
