#1
Front (Question)

What are the two type of white blood cells

Back (Answer)

.Phagocytes . Lymphocytes

#2
Front (Question)

What is the role of phagocytes

Back (Answer)

. To ingest and destroy the pathogen before it can cause harm They provide an important defence against pathogens that manage to enter the body

#3
Front (Question)

Describe step 1 of phagocytosis

Back (Answer)

. The phagocyte is attracted to the pathogen by chemical products of the pathogen. It moves towards it along a concentration gradient

#4
Front (Question)

Describe step 2 of phagocytosis

Back (Answer)

The phagocyte has several receptors on its cell surface membrane that attach to chemicals on the surface of the pathogen

#5
Front (Question)

Describe step 3 of phagocytosis

Back (Answer)

. The phagocyte engulfs the pathogen to form a vesicle called a phagosome Lysosomes within the phagocyte migrate towards the phagosome

#6
Front (Question)

Describe step 5 of phagocytosis

Back (Answer)

. The lysosomes contain enzymes called lysozymes, and they release these enzymes into the phagosome which destroy the ingested bacteria/pathogen by hydrolysis of their cell walls

#7
Front (Question)

What is step 6 of phagocytosis

Back (Answer)

The soluble products from the breakdown of the pathogen are absorbed into the cytoplasm of the phagocyte
