Immune system SL - Injury and inflammation

Substance that triggers vasodilation

• prostaglandins

• histamine

• heparin

• immunoglobin

They migrate by amboid movement from the vessels to the place of injury

• pathogens

• phagocytes

• platelets

• erythrocytes

First reaction of the organism to injury includes:

• vasodilation

• vasoconstriction

• increased permeability of blood vessels

• blood clotting

Substance released at the place of infection to trigger inflammation

• histamine

• antibody

• prostaglandin

• absces

Cells responsible for phagocytosis in the place of injury:

• neutrophils

• macrophages

• eosinophils

• basophils

During phagocytosis, a phagosome with engulfed pathogen links to:

• lysosome

• lysozyme

• Golgi apparatus

• plasma membrane

Parts of phagocyte that surround pathogens to be engulfed is called:

• pseudopodia

• cell walls

• Golgi apparatus

• vacuoles
