The phagocytes are the white blood cells that change shape to engulf/consume pathogens via phagocytosis There are different types of lymphocytes with different functions Type b produce the antibodies and another type produce antitoxins to neutralise the toxins produced by the microorganisms
Can i ask a general question? I know i wont need this information for the exam but im curious to know. Since the blood does not flow like a river but in are veins and arteries, how does the platelets heal the wound? does it diffuse? or some other process? Thank you!
So basically - the platelets will just be in the blood, and they'll bind to the wound as they float by. They'll be attracted by chemicals that are released from the wound, and there also will be receptors they can bind on to. Hope that helps!
