produce antibodies

Question 3

phagocytosis

Question 4

what are the functions of eosinophils?

Answer 4

help kill of parasitic worms

Question 5

what are the functions of basophils?

Answer 5

help create inflammation process, allergic reaction

Question 6

what are erythrocytes?

Answer 6

red blood cells

Question 7

what are leukocytes?

Answer 7

white blood cells

Question 8

what are thrombocytes?

Answer 8

platelets

Question 9

what are the functions of erythrocytes?

Answer 9

carry O2 to body cell

Question 10

what are the functions of thrombocytes?

Answer 10

helps with coagulation

Question 11

what are megakaryocytes?

Answer 11

large bone marrow cells with a lobulated (multiple lobes) nucleus

Question 12

what are the functions of megakaryocytes?

Answer 12

production of thrombocytes

Question 13

what are the two major categories of the immune system?

Answer 13

1. innate defenses
2. adaptive defenses

Question 14

what is the first line of defense?

Answer 14

surfaces barriers

Question 15

what is the second line of defense?

Answer 15

internal defenses

Question 16

what are the steps to inflammation?

Answer 16

• initiated by proinflammatory chemicals
• chemicals trigger
  vasodilation, increased capillary permeability, recruitment of immune cells to the site
• the contents of exudate (inflammatory fluid & cellular/protein mixture) help eliminate the pathogen and promote healing

Question 17

what is the adaptive immune system?

Answer 17

Cells and defenses that are activated only upon exposure to a specific pathogen; response time is slower but stronger (compared to innate defenses), and results in long-term immune memory

Question 18

what is the innate immune system?

Answer 18

Cells and mechanisms with broad specificity, offering protection against numerous different pathogens; defenses are present at birth (“innate”); response time is very fast

Question 19

what is cell-mediated immunity?

Answer 19

Immune defenses conferred by helper and T-cells

Question 20

what is the Antibody-mediated immunity (humoral immunity)?

Answer 20

Antibody-based immune defenses provided by B-cells

Question 21

what is the difference between the innate immune system and the adaptive immune system?

Answer 21

innate immune response is broad and immediate; adaptive immune response is slower but stronger, specific, and results in long-term immune memory
