5.2 Physiology of the Lymphatic System and Immunology Part 3 Flashcards
What happens to he vacuole that is formed inside of a neutrophil?
fuses will lysosomes which will destroy the pathogen
What happens to neutrophils after they have killed a pathogen?
short lifespan, they die right after
How do neutrophils exit the body after an infection?
pus
What does the composition of a neutrophil look like when stained?
granules; multi lobed nucleus
What are eosinpohils responsible for?
respond to allergic reactions and parastitic infections
What do eosinophils look like under the microscope?
similar to neutrophils but their granules stain darker pink and are less commonly seen
What are the rarest granulocytes?
basophils
What are basophils responsible for?
releasing histamines and heparin
What are histamines?
vasodilators that increase the blood flow
What is heparin?
anticoagulant that helps prevent the formation of blood clots
What does morphology mean?
shape
What does the composition of basophils looks like?
darker stained granules than both neutrophils and eosinophils
What are the two types of agranulocytes?
lympthocytes
monocytes
What are monocytes?
large white blood cells with a U or kidney bean shaped nucleus
What are macrophages?
monocytes that have moved into the tissue
What are the greatest phagocytes of all the blood cells?
macrophages
Why are macrophages better at phagoctyosis than neutrophils?
live longer
What are the three major types of lymphocytes?
T cells
B cells
natural killer cells
What does the specific immune response depend on?
activity of the lymphocytes
What are some lymphocytes functions?
making antibodies
attacking foreign cells
destroying body cells that have lost normal function
