Flashcards in Simplified Immune Cards based on study guide Deck (16):
1

External Pathogens

bacteria, viruses, fungi, and parasitic protists

2

abnormal human body cells

ex. cancer

3

lymph vessels

tubes that run parallel to the circulatory vessels (arteries and veins) and serve as a blood filtration system to remove foreign particles

4

Lymph Nodes

Oval shaped organs in the armpits, neck, etc. that are connected to lymph vessels
collect foreign particles and store B and T cells

5

Spleen

stores blood cells, removes clumped pathogens coated with antibodies form the blood stream

6

Adenoids (tonsils)

trap pathogens

7

Bone Marrow

stem cells within the bone marrow differentiate into blood cells
location where B lymphocytes mature

8

Thymus

organ in the neck that is used to create and promote maturation of T lymphocytes

9

T or F: Plants and all animal have nonspecific immune responses

true
there responses attack all pathogens in the same way

10

Hypersensitivity response

plants
cells that come in direct contact with pathofen undergo apoptosis and signal other nearby cells to improve defenses in cell wall

11

Physical barriers

part of first line of defense
skin mucous membranes, cilia lining respiratory tract
try to keep pathogens out

12

Chemical barriers

first line of defense
sweat (acidic) tears and saliva (lysozyme) stomach acid (SO ACIDIC IT IS UNREAL)

13

Leukocytes

second line of defense
phagocytic white blood cells that swallow foreign stuff
ex. macrophages

14

Inflammatory response

cells release histamine (dilation of blood vessels)
blood supply increases to injury (redness, warming, swelling) m
leukocytes come to swallow and digest pathogens

15

Fever

widespread inflammatory response, high temp interferes with bacterial and viral activity

16

True or False: all animals have specific immune responses

false, only vertebrates have responses that develop over time because of encounters with specific pathogens
