Flashcards in Chapter 6: Blood & The Lymphatic & Immune Systems Deck (68):
1

Platelets

Initiates blood clotting process

2

What are the formed elements of blood cells?

Erythrocytes
Platelets
Leukocytes
Plasma

3

The average adults has how much blood?

5 liters

4

Hematopoiesis

The process in which blood cells are produces in red bone marrow

5

What are the proteins in plasma?

Albumin
Globulin
Fibrinogen

6

Albumin

Helps transport fatty substances

7

Globulin

Gamma globulins are antibodies

8

Fibrinogen

Blood clotting Protein

9

What are red blood cells?

Enucleated erythrocytes

10

What gives red blood cells their color?

Hemoglobin

11

What is the lifespan of a red blood cell?

120 days

12

What are White blood cells?

Leukocytes that provide protection against pathogens.

13

What are the 2 categories for white blood cells?

Granulocytes
Agranulocytes

14

Granulocytes

Have granules in cytoplasm

15

Agranulocytes

No granules in cytoplasm

16

What are the 3 types of granulocytes?

Basophils
Eosinophils
Neutrophils

17

Basophils

Release histamine & heparin to damaged tissue

18

Eosinophils

Destroy parasites & increase during allergic reaction

19

Neutrophils

Important for phagocytosis

20

What are the 2 types of Agranulocytes?

Monocytes
Lymphocytes

21

Monocytes

Important for phagocytosis

22

Lymphocytes

Provide protection through immunity

23

What are platelets?

Also known as thrombocytes, they are critical in clotting. They lead to the formation of thrombin.

24

Agglutinate

Clots that form into small clusters when blood vessel is damaged.

25

Thrombin

Converts fibrinogen to fibrin.

26

Type A Blood

Produces anti-B antibodies that attack type B & AB blood.

27

Type B Blood

Produces anti-A antibodies that attacks type A & AB blood.

28

Type O Blood

Produces anti-A & anti-B antibodies that attacks type A, type B, & type AB blood.

29

Type AB Blood

Produces no antibodies that does not attack any other type of blood.

30

Universal Donor

A type O blood that does not have an antibody, so it will not attack any blood type.

31

Universal Recipient

A type AB blood that has no antibodies against other blood types and therefore, receive any type of blood.

32

Rh+

Will not make anti-Rh antibodies

33

Rh-

Will produce anti-Rh antibodies

34

agranulocyte

white blood cell without granules

35

sanguinous

pertaining to blood

36

thrombocytosis

condition of having too many platelets

37

thronbopenia

condition of having too few platelets

38

Hemoglobin

Blood protein

39

What are the 5 organs of the lymphatic System?

Lymph nodes
Lymphatic vessels
Thymus gland
Spleen
Tonsils

40

Lymph

fluid within lymphatic vessels

41

Lacteals

lymph vessels around the small intestine that assists with fat absorption

42

Lymphatic Vessels

One-way pipe conducting lymph from tissues toward thoracic activity using valves to prevent backflow

43

What is the progress of lymphatic vessels?

Lymph capillaries in tissues merge into larger lymph vessels that drain into one of two large lymphatic ducts in thoracic activity

44

Lymph Nodes

Removes pathogens & cell debris from lymph as it passes through
Traps and destroys cells from cancerous tumors

45

Tonsils

Collections of lymphatic tissue located on each side of throat

46

What are the 3 sets of tonsils?

Palatine
Pharyngeal
Lingual

47

Spleen

Consists of lymphatic tissue that is highly infiltrated with blood vessels

48

What is the function of a spleen?

Phagocytic macrophages line blood sinuses to remove pathogens
Filters out and destroys old red blood cells, recycling iron

49

Thymus Gland

Secretes hormone
Changes lymphocytes to T Lymphocytes (T Cells)

50

Whaat are the 2 forms of immunity?

Natural
Acquired

51

Natural Immunity

Doesn't require prior exposure to pathogen

52

Acquired Immunity

Body's response to a specific pathogen
May be either Passive or Active

53

Passive Acquired Immunity

When a person receives protective substances produced by another human or animal

54

Active Acquired Immunity

Develops following direct exposure to pathogen
Stimulates immune response

55

Immune Response

Antigens stimulate immune response

56

What are the 2 different processes of Immune Response

Humoral immunity
Cellular Immunity

57

Humeral Immunity

Production of B lymphocytes

58

Cellular Immunity

Produces T Cells and Natural Killer Cells

59

Nosocomial Infection

Acquired in the hospital

60

Cross Infection

Pathogen acquired from another person

61

Reinfection

Becomes infected again with same pathogen

62

Self-Inoculation

Pathogen from one part of the patient's body spreads to another part of the body

63

axillary

pertaining to the underarm region

64

immunoglobulins

antibodies secreted by B cells; assist in protecting the body

65

inguinal

pertaining to the groin region

66

lymphangial

pertaining to the lymph vessels

67
