Lab 1: Hemostasis Flashcards
F of an ERYTHROCYTE
F - Transports O2 and CO2
What is another name for an ERYTHROCYTE?
A RED BLOOD CELL (RBC)
F of a NEUTROPHIL
F - Phagocytic (engulfs bacteria, fungi)
F of a LYMPHOCYTE
F - Produces a specific immune response by direct cell attack or via antibiotics
F of a MONOCYTE
F - Develops into a phagocytic macrophage; triggers specific defenses by presenting antigen to T-cells
F of an EOSINOPHIL
F - Releases enzymes to destroy parasites; dec. allergic response by engulfing anti-body labelled materials
F of a BASOPHIL
F - Releases histamine to trigger inflammatory response; involved in allergic response
F of THROMBOCYTES
F - Forms plug to seal small tears in blood vessels; releases chemicals that stim. blood clotting
What is another name for THROMBOCYTES?
PLATELETS
What is the S of a RBC and why is it beneficial for the cell to be shaped that way?
S - Bioconcave
This is beneficial because the bioconcave shape makes the SA of the RBC larger and able to carry more O2
Which WBCs are classified as GRANULOCYTES?
NEUTROPHILS, EOSINOPHILS, and BASOPHILS
Which WBCs are classified as AGRANULOCYTES?
MONOCYTES and LYMPHOCYTES
What are some of the major components of PLASMA?
Water, proteins, electrolytes, nutrients, gases, waste products
What are 3 primary classes of PLASMA proteins?

Where are the 3 primary classes of PLASMA proteins produced?
In the LIVER

2 - 4%
Normal range for BASOPHILS?
0.5 - 1%

Why is a differential count more useful than a total WBC count?
Because you cansee more specifically which WBCs are elevated and possibly learn why according to what is found.
