Question 3

__ in involved in the acquisition of nutrients for some cells, and, in the immune system, it is a major mechanism used to remove pathogens and cell debris

Answer 3

phagocytosis

Question 4

several types of cells in the immune system engulf microorganism via __

Answer 4

phagocytosis

Question 5

_ are abundant in the blood, quickly enter tissues, and phagocytize pathogens in acute inflammation

Answer 5

neutrophils

Question 6

_are closely related to monocytes in the blood. Longer-lived cells predominate in chronic inflammation

Answer 6

Macrophages

Question 7

___ is a small amount of phagocytosis in these cells is often necessary in order for them to develop into cells that release antibodies

Answer 7

B lymphocytes

Question 8

where does phagocytosis begins

Answer 8

begins with the neutrophils or macrophage flowing around the pathogen and engulfing it

Question 9

where does phagocytosis begins

Answer 9

begins with the neutrophils or macrophage flowing around the pathogen and engulfing it

Question 10

2nd step of phagocytosis

Answer 10

fusion of lysosomes (phagolysosomes)

Question 11

where does the lysosomes derived from

q

Answer 11

golgi apparatus

Question 12

materials

Answer 12

glass slide
sterile needle and syringe
EDTA tube
innoculating loop
bacterial broth culture consisting of a muxture of bacteria
alcohol lamp
hema-quick stain
pasteur piptte
water bath

Question 13

Procedure:

Answer 13

1. Collect 3ml of venous blood in EDTA tube using aseptic technique
2. Add 2-3 drops of bacterial suspension and mix by gentle shaking
3. Incubate the tube at 37C in a water bath for 30 mins
4. Centrifuge the tube for 5minutes
5. Using pasteur pipette, make a smear in a glass slide
6. Stain the smear using hema-quick stain
7. Examine under oil immersion objective for the presence of micro organisms within the leukocytes

Question 14

Phagocytosis in these cells is important for the elaboration of a specific immune response rather than for directly destroying the pathogens

Answer 14

Dendritic cells
