HUMAN DEFENCE MECHANISM

Pathogen enters our body through

• Skin

• Respiratory system

• Digestive system

• All above

Our body has 3 lines of body defence to fight pathogens

• True

• False

Our first line of body defence is

• Antibodies

• White blood cells

• Skin

White blood cells fight the phatogen through ...... process

• Phagocynisis

• Phagorytosis

• Phagocytosis

• Phagolysis

In third line of body defence, pathogen will fight with

• Red blood cell

• White blood cell

• Antibody

• Anybody

Pathogen will enter the skin if there is a....on the skin

• Wound

• Injured

• Hole

• Food

Mucuos membrane is the membrane that produced mucous along the

• Reproductive system

• Digestive system

• Respiratory system

• Lymphatic system

Diagram shows a process of

• Erytrocytisis

• Phagocytosis

• Parolysis

• Phagonisis

Third line of body defence involving the production of

• Antiserum

• Antibody

• Anybody

• Antivaccine

What happen in the diagram?

• Antibody stick up all antigens into a lumps

• Antigen stick among themselves to build an large lump

• Antibody release toxin to kill antigens

• Antigen absorbs nutrien from antibody
