immune tings

Question 1

immunity

Answer 1

the ability of the body to stop pathogens toxins etc to cause bodily harm and kill them.

Question 2

cell-mediated responses

Answer 2

when T cells bind to antigen-presenting cells and stimulate an immune response. it stimulates t helper cells and activates t cytotoxic cells and b cells

Question 3

primary response

Answer 3

the initial body response from being stimulated by the antigens and b cells secreting antibodies

Question 4

secondary response

Answer 4

memory b cellls rapidly secreting antibodies for a effective immune response.

Question 5

non specific immunity

Answer 5

Question 6

immune response

Answer 6

antigen-presenting cell stimulated/ activate t cell

t cell goes under clonal selection

t cell form t helper and t c cell

t helper cell stimulate phagocytes and b cells

b cell with complementary antibody go under clonal selection,

b memory and plasma cells

Question 7

humoral

Answer 7

antibodiews and b cells

Question 8

antibodies

Answer 8

They cause agglutination of the bacterial cells (Figure 2). 1n this
way clumps of bacterial cells are formed, making it easier for the
phagocytes to locate them as they are less spread-out within the body.
• They then serve as markers That stimulate phagocytes to engulf the
bacterial cells 10 which they are attached.
