Transcript of GRANULOCYTE (white blood cells)

White Blood Cells Granulocytes Eosinophils Neutrophils Basophils Function less than 1% of WBCs
play a part in allergies releases histamine and heparin
clears the way for neutrophils 10 to 15 u diameter. Basophils make up 0.5 to 1.0% of leukocytes. The nucleus consists of 2 to 3 lobes. The cytoplasm is full of purple granules. Leukemia cancer that develops in white blood cells
too many leukocytes are made
the blood is flooded extra WBCs Function kill bacteria (5-20 each)
"the fighting force" Aids infection of white blood cells by the HIV virus
generates more virus until the cell dies Eosinophils have large granules.The granules have digestive enzymes that are help fight against larva. The numbers of eosinophils are seen much more in an allergic reaction when occurring. These extra cells help the body respond if asthma or hay fever were to occur. Eosinophils help the body with phagocytosis. This is when the eosinophil gathers around and consumes a bacterium, eating it whole. This helps remove diseases causing bacteria in the body. white blood cells that produce chemicals in the form of granules that fight pathogens
4,000-10,000 per μL
12-15μm
Multi-lobed nucleus
formed in the bone marrow
classified as basophils, esinophils, and neutrophils
These cells are 70% of leukocytes and have 2 to 5 nuclear lobes connected by filaments of chromatin.
if the production of of nuetrophils is produced it can result in Neutropenia
# increases during infection
make up 58% of WBCs
Phagocytosis devouring of other cells
neutrophils consume bacteria Eosinophils can move from the blood into the body tissues through diapedesis. This allows the leukocytes to attack off infections in the tissues directly. heparin prevents blood from clotting too quickly
histamine increases blood flow to tissues 10 to 15 um diameter,
Eosinophils make up 2.0 to 4.0% of leukocytes. cells contain a two lobes nucleus (that are usually connected) and a cytoplasm
