First step of phagocytosis
WebApr 28, 2016 · The first step of hemostasis is when blood vessels constrict to restrict the blood flow. Next, platelets stick together in order to seal the break in the wall of the blood vessel. Finally, coagulation occurs and … WebFinal answer. Step 1/7. When a tissue is injured, defensive leukocytes immediately arrive via hyperemia, which is the increased blood flow achieved by vasodilation. In endothelial cells, selectins are produced at the site of injury to snag leukocytes to their sticky membrane. This leukocyte adhesion to the vessel wall is called margination.

WebThe first step in phagocytosis is the detection of the particle by phagocytes. This, as mentioned before, is accomplished by specialized receptors on the cell membrane. Foreign particles, such as microbial pathogens, can be recognized directly by receptors that bind molecules not found in higher organisms, or indirectly through opsonins.
