exercise 18 Flashcards
plasma
fluid portion of the blood; allows blood to flow; composed primarily of water, but also carries many chemicals including a variety of ions, dissolved gasses, proteins, and hormones; of the approximately 5.5 L of whole blood in a person, approximately 3 L are plasma
formed elements of the blood
erythrocytes, leukocytes, platelets; each began as a nucleated cell in the red bone marrow
leukocytes
WBC; 4,000-11,000 per microliter
Granulocytes
neutrophils, eosinophils, basophils
agranulocytes
monocytes, lymphocytes
monocytes
largest; oval, kidney shaped nucleus
lymphocytes
smallest; round, slightly indented nucleus that may nearly fill the cell
neutrophils
most common; multilobed/segmented nucleus
eosinophil
bilobed nucleus
basophils
least common and have so many granules that the round nucleus is often not visible
platelets
thrombocytes; membrane-bound fragments of cytoplasm that come from megakaryocytes; function in the plasma; 150,000-450,000 per microliter
erythrocytes
RBC; mature have no nucleus; biconcave; flexible and can be deformed; smaller than leukocytes but larger than platelets; 3.9-5.6 million per microliter
antigens
agglutinogens; found on cell membrane of erythrocytes; serve as markers or name tags
antibodies
agglutinins; produced by lymphocytes and added to the blood
minor agglutination
the antibodies in the donated blood react with the antigens on the erythrocytes in the recipient blood
major agglutination
the recipient receives the incorrect antigens on the erythrocytes in the donated blood
whole blood
connective tissue that is composed of a fluid matrix and formed elements
when an antibody interacts with an antigen on the surface of your erythrocytes, it forms
an immune complex
the formation of immune complexes forms
antibody bridges; bc one antibody can bind to antigens on 2 erythrocytes and bc one erythrocyte has the ability to bind with many antibodies
agglutination
the clumping of the erythrocytes due to the interaction btwn the antibodies and erythrocyte antigens
washed erythrocytes
have had all plasma and plasma contents removed
gene
segment of DNA that codes for a trait
