Lymphatic System

Question 0

Lymph node

Answer 0

Lymphoid organ that serves as a battleground for immune responses

Question 1

Lymph

Answer 1

Fluid that drained into vessels of lymphatic system

Question 2

Lymphocyte

Answer 2

A T cell or B cell

Question 3

Antigen

Answer 3

Molecular configuration that certain lymphocytes recognize as nonself and that triggers immune response

Question 4

Phagocyte

Answer 4

Cell that captures prey by phagocytosis, defend and perform cell maintinence

Question 5

Complement proteins

Answer 5

Circulate in inactive form in vertebrate’s blood, can promote inflammation, lysis of pathogens, and stimulate phagocytes during nonspecific defenses and immune responses

Question 6

Interferons

Answer 6

Proteins made by host cell to communicate presence of pathogen, inhibit virus reproduction in neighboring cells, 1st line of defense

Question 7

Inflammatory response

Answer 7

Total system response to pathogen, fever

2nd line

Question 8

Cell mediated response

Answer 8

Responding on a cellular level, specialized defense

3rd line

Question 9

T - Lymphocytes

Answer 9

Type of white blood cell
Helper t: makes and secrets chemicals to induce t and B cells to divide
Cycotic t: touch-kills infected body cells, such as cancer

Question 10

Memory T cells

Answer 10

Remember previous infections and then awake to fight and kill them off when they return

Question 11

Helper T cells

Answer 11

Secretes chemics that induce t and B cells to undergo division into effector and memory cells

Question 12

Cytocotic T cells

Answer 12

Touch-kills infected or altered body cells, such as cancer

Question 13

B lymphocytes

Answer 13

Produces antibodies

Question 14

Humoral immunity

Answer 14

Circulation of antibodies, 2nd line, uses B cells

Question 15

Macrophages

Answer 15

Phagocycotic white blood cell, nonspecific defense and immune responses,

Question 16

natural killer cells

Answer 16

Cytotoxic lymphocyte that looks for tumor or virus infected cells and then touch kills them

Question 17

Neutrophils

Answer 17

Most abundant fastest acting WBC, phagocytizes bacteria

Question 18

Basophils

Answer 18

Fast acting WBC, secretions cause vasodilation during inflammatory response

Question 19

Antibodies

Answer 19

Binds to antigen, only made by B cells

Question 20

WBC

Answer 20

Fight disease and take part in defense

Eosinophils neutrophils macrophages t or B cells

Question 21

MHC markers

Answer 21

Marker cells, carry bite of cellular material to cell surface, give cell a fingerprint

Question 22

Histamine

Answer 22

Released into blood during immune responses and allergies

Question 23

Pathogen

Answer 23

Harmful invader, virus or bacteria
