phagocytosis Flashcards
What are the two types of white blood cells
Phagocytes and lymphocytes
What does phagocytosis do
White blood cells called phagocytes engulfs the pathogen for example bacteria
What is the process of phagocytosis
Chemical products of pathogens or dead damaged and abdominal cells acts as attractants causing phagocytes to move towards the pathogen
Phagocytes have several receptors on their cell surface membrane that recognise and attach to chemicals on the surface of the pathogen
They engulf the pathogen to form a vesicle know as a phagosome
Lysosomes fuse move towards the vesicle and fuse with it
Enzymes called lysozymes are present within the lysosomes. These lysozymes destroy ingested bacteria by hydrolysisnf lot of Thor cells walls. The process is the same as that foe the digestion of food in the intestines .they mark smaller untilp there soluble.
