What are the two types of immune responses?

Answer 2

nonspecific
specific

Question 3

What is the nonspecific immune response known as?

Answer 3

innate immune system

Question 4

What is the innate immune response?

Answer 4

first line of defense through physical and chemical barriers to prevent pathogens from entering the body

Question 5

Which immune response acts quickly?

Answer 5

nonspecific

Question 6

Answer 6

several days

Question 7

What is the specific immune response also known as?

Answer 7

adaptive immune system

Question 8

Question 10

What is the integumentary system?

Answer 10

skin

Question 11

What immune response is the skin a part of?

nonspecific

Question 12

What are normal flora?

Answer 12

good bacteria

Question 13

What do normal flora produce?

Answer 13

lactic acid which inhibits pathogenic bacteria

Question 14

How does the stomach help the nonspecific immune response?

Answer 14

stomach acid and digestive secretions helps destroy microorganisms

Question 15

How does the respiratory system help the nonspecific immune response?

Answer 15

mucus will trap pathogens

Question 16

What immune response are fevers and the inflammatory response a part of?

Answer 16

nonspecific

Question 17

What is the inflammatory response?

Answer 17

localized response in the tissue where increased blood flow goes to the infected region causing swelling

Question 18

What is tissue swelling?

Answer 18

when blood vessels in the affected area dilates increasing the number of immune cells responding to the infection

Question 19

What helps bring a conscious awareness to an infection?

Answer 19

redness and pain caused by the increase in blood flow to the affected area

Question 20

What are cytokines?

Answer 20

secreted proteins that help regulate and signal both specific and nonspecific immune systems
