7. Blood About 5 liters in average adult
Mixture of formed cells (erythrocytes, leukocytes and platelets) and plasma
Hematopoiesis: formation of blood cells
Purposes: transport(RBC), protection (WBC), control of bleeding (platelets)

8. Components of Blood

9. Plasma
55% of whole blood
90-92% water
8-10% dissolved substances

10. Erythrocytes Biconcave and enucleated Hemoglobin
About 5 million per cubic centimeter
Average life span is 120 days

11. Leukocytes
Provide protection from pathogens like bacteria, viruses, and others
About 8,000 per cubic centimeter

12. Platelets Thrombocytes
Between 200,000 and 300,000 per cubic centimeter
Hemostasis: blood clotting

13. Blood Typing Type A Type B Type AB (universal recipient)

16. Standard Precautions Vocabulary
Nosocomial infection: Infection caught at medical facility
Cross infection: contaminate others
Reinfection: re-contaminate self
Self-inoculation: spread infection on self
OSHA: Occupation Health and Safety Administration – keeps employees safe at work

17. Vocabulary/Pathology
Allergen: substance that can cause allergic reaction
Anaphylactic shock: severe allergic reaction
Acquired Immunodeficiency Syndrome (AIDS): symptoms of the HIV virus
Autoimmune disease: immune system attacking own body
Human immunodeficiency virus (HIV): virus causing AIDS
Inflammation: body’s response to injury
Opportunistic infection: infection appearing in immunocompromised person
Vaccination: immunity to virus through injection – “immunization”

18. Abbreviations AIDS: acquired immunodeficiency syndrome
ELISA: enzyme-linked immunosorbent assay
HIV: human immunodeficiency virus
KS: Kaposi’s sarcoma
Mono: mononucleosis

19. Lymphatic System
Consists of lymphatic vessels, lymph nodes, spleen, thymus gland and tonsils
Immunity
Lymph
Lacteals: in abdomen,
Used for fat metabolism

20. Lymphatic Vessels
One way pipes
Very low pressure so have valves

21. Lymph Nodes Collection of lymphatic tissue Remove pathogens and
cell debris

22. Tonsils Collection of lymph tissue along lymph vessels Palatine
Pharyngeal (adenoids)
Lingual

23. Spleen
LUQ
Filters and destroys old red blood cells, recycles iron, and stores some of the blood supply for body
Macrophages engulf and remove pathogens

24. Thymus Gland
Behind the sternum
Develops the immune system

25. Immunity
Body’s ability to defend self against pathogens like bacteria, viruses, toxins, and cancer cells
Natural immunity (innate)
Acquired immunity (have to get)
Passive
Active
