| 1 |
formed elements-
|
white blood cells-red blood cells-platelets
|
|
| 2 |
white blood cells list-function-aka-
|
-neutrophils, eosinophils, basophils, lymphocytes, monocytes-provide protection against pathogens-leukocytes
|
|
| 3 |
which formed element has the most cells?
|
-red blood cells
|
|
| 4 |
platelets made of-purpose of platelets-average number-
|
-fragments of other cells known as megakaryocytes-key in blood clotting-130,000-400,000
|

|
|
| 8 |
difference between granulocytes and agranulocytes
|
-granulocytes have spotted cytoplasm as a result of membrane bound organelles
|
|
| 9 |
purpose of neutrophil-what causes number to increase-average percent-
|
-phagocytize bacteria-release antimicrobial chemicals-increases in bacterial infections-60-70%...
|
|
| 10 |
purpose of eosinophils-what causes an increase-average percent-
|
-phagocytize antigen-antibody complexes, allergens, and inflammatory chemicals-release enzymes...
|
|
| 11 |
function of basophils-increase in cell production-average percent-
|
secrete histamine (vasodilator) which increases blood flow to a tissue-secrete heparin (anticoagulant)...
|
|
| 12 |
function of lymphocytes-increase in cell-percent-
|
destroy cancer cells, cells infected with viruses, and foreign cells-present antigens to activate...
|
|
| 13 |
function of monocytes-increase in production-percent-
|
-differentiate into macrophages (phagocytic cells of tissues-phagocytize pathogens, dead neutrophils...
|
|
| 14 |
blood tests list-
|
hematocrit-differential white blood cell count
|
|
| 15 |
differential white blood cell count purpose-
|
to count the number of each white blood cell in a sample of blood.-with the information found...
|
|
| 16 |
hematocrit what does it check-purpose-
|
-checks plasma and formed elements lever-useful to find if individual has anemia -can find...
|
|
| 17 |
hematocrit normal range male-female-
|
-42-52 percent formed elements-37-42 %formed elements
