The Immune System

what is Innate/Non-specifc Immunity

what are 1st and 2nd inborn defense
against anything foreign

what is the Adaptive Immunity

what are the developed 3rd defense

against specific invaders

What are the host defenses categorized by

Innate/nonspecific immunity

• 1st

  • Intact skin, Mucous membranes, and their secretions, Normal microbiota

• 2nd

  • Natural killer cells and their phagocytic WBCs, Inflammation, Fever, Antimicrobial substances

Adaptive/acquired immunity

• 3rd line of defense

  • T cells and B cells, Antibodies

what is 1st, and attributes

what is Innate immunity
Skin layers must be intact
Barriers always renewed
Mucous traps microbes

what are the 1st Line Defense Fluids

origin of the tears, saliva, perspiration, nasal secretion
- wash and antibacterila action

what are the 1st Line Defense Movement

what are the flow of fluids such as urine

what are the 2nd line of defense

cells and chemicals

what are the 2nd line of defense attributes

what are the phagocytes that eat microbes. natural killer cells. consist of neutrophils and macrophages

what are the 2nd line of defense proteins

Interferons and Complemets
Infterferons stop vrisues from eations

what is the The Complement System (2

the 2nd defense
- Proteins poke holes in invader cells
Attract eaters/phagocytes
Tag microbe cells for destruction

What is inflammation

what is the response of tissue to an injury, often by invading microbes

what are the attributes of inflammation 2nd

what are the belongings of
Increased blood flow, which causes
- heat, redness, swelling (edema), pain

what are the 5 inflammations

Blood supply increases

2. White cells come to area and release Histamine

3. Clotting proteins

• Trap bacteria behind clot

4. Phagocytes attracted to site

• Neutrophils & macrophages eat & die

5. Pocket of dead cells = pus

  must be cleared

Fever is a

Defense

what is a Fever

what is the defense of abnormal high temp

• bodys normal response to inflammation and infection

• stimulated by toxins. produce chemicals caled pyrogens

what is the 3rd line of defense

Adaptive/Specifc immunity

3rd line of defense

Antibody mediated Immunity (humoral)
Call mediated immediate

vaccine or the encounter of foreign body give

what give memory or immunity

what are the attributes of Vaccine sunder 3rd/Adaptive

Antigens: proteins on surface of microbe
Antibodies: proteins made in defense of antigen

what are antibodies

what are proteins made by body, t or y structure

what are antigens

attacked by millions of different antibodies

relation of antibodies and antigens

Each antibody molecule can bind 2 antigen molecules

what is the relation of antibodies and antigens

each antibody molecule can bind 2 antigen molecules
