Lesson 23.2 - Innate Immune Response

Question 1

Serves as the frontline of defense by the body against pathogens and invaders. Involves surface barriers and non-specific immunity cells

Answer 1

Innate Immune System

Question 2

Already present at birth. Serves as barrier for the entry and spread of microorganisms in the body. Action happens at the same speed every time there is an invader.

Answer 2

Innate Defenses

Question 3

Surface Barriers

Answer 3

Skin
Mucuos Membranes

Question 4

_________ is the first line of defense of the body. Equipped with impenetrable __________.

Answer 4

Skin and Epithelium

Question 5

when the skin is wounded it becomes vulnerable to _________, when this happens, the second line of defense comes to play.

Answer 5

pathogens

Question 6

__________ are internal surfaces that protect epithelial cells from damage

Answer 6

Mucosae

Question 7

______ are hairlike structures present in epithelial cells. It serves to clean the tract by removing the mucus.

Answer 7

Cilia

Question 8

Internal Defenses

Answer 8

Phagocytes
Natural Killer Cells
Inflammation

Question 9

Respond to bacterial infections and the formation of tumors. Capable of targeting pathogens. Tags any infected cells that need to be destroyed

Answer 9

Natural Killer Cells

Question 10

The process of engulfing pathogens in order to destroy them

Answer 10

Phagocytosis

Question 11

Provides immediate actions to protect the body against pathogens

Answer 11

Innate Immune Response

Question 12

Innate Immune Response has two parts, what is it?

Answer 12

recognition of pathogen and effector mechanism

Question 13

Part of the innate immune response, which soluble proteins and cell-surface receptors recognize and bind with the pathogen.

Answer 13

Recognition of pathogen

Question 14

Part of the innate immune response, wherein cells engulf, kill or attack pathogens

Answer 14

Effector Mechanism

Question 15

An immune response in the presence of pathogens. Caused by white blood cells and discharged substances that contribute to ________.

Answer 15

Inflammation

Question 16

Phagocyte mobilization (from innate defences to internal defences) (like samad)

Answer 16

1. Leukocytosis - neutrophils enter the blood from bone marrow
2. Marginations - neutrophils cling to the capillary wall
3. Diapedesis - neutrophils flatten and squeeze out of the capillaries
4. Chemotaxis - neutrophils follow chemical trail
