-
Which of the four basic tissue types is blood?
Connective tissue
-
What are the two basic components of blood?
.Formed elements
.Plasma
-
Most abundant, influences blood volume, pressure, and flow via osmotic pressure and viscosity.
Albumins
-
Involved in solute trnasport, clotting, and immunity (antibodies)
Globulins
-
Involved in clotting (precursor to the sticky protein that from clot framework)
Fibrinogen
-
What do we call the percentage of whole blood contributed by formed elements?
Hematocrit
-
What is the technical term for red blood cells?
Erythrocytes
-
Describe the shape of a red blood cell
Bi- concave disc
-
why don't red blood cells use oxygen or replicate themselves?
Lack mitochondria
Lack a nucleus
-
what do we call the the small, enzyme containing membranous sacs resulting from the fragmentation of megakaryocytes that adhere to damaged blood vessels and assist in clotting?
Platelets
-
What is the technical term for white blood cells?
Leukocytes
-
what kinds of white blood cells are granular (stain with a neutral dye), have a multi-lobed nucleus, and are active phagocytes?
Neutrophils
-
What kinds of white blood cells are granular (stain red with an acidic dye), have a bi-lobed nucleus, and phagocytize antigen/antibody complexes, allergens, and inflammatory compounds as well as releasing enzymes that destroy some parasites (e.g. worms)?
Eosinophils
-
What kinds of white blood cells are granular (stain purple with a basic dye), and secrete histamine (vasodilator) and heparin (anticoagulant) that promote inflammation.
Basophils
-
What kinds of white blood cells are agranular, the largest of WBCs, have a kidney-bean shaped nucleus, and become macrophanges outside the bloodstream.
Monocytes
-
What do we call the former monocytes that act as aggressive phagocytes, roam the body, and may attract other WBCs as well as fibrocytes that may isolate the infected area in scar tissue?
Free marcophages
-
What do we call aggressive phagocytic cells (such as microglia and osteoclasts) that are permanent residents of particular connective tissues?
Fixed marcophages
-
what kind of white blood cells are agranular, have very little cytoplasm around a large nuclus, and are responsible for both non-specific and specific immunity (the ability to respond to invaders on an individual basis, including the ability to retain information regarding past infections)?
Lymphocytes
-
Attack bacteria, transplanted cells, and host cells with viral infection or cancer, and intracellular parasites directly (provides specific defense, produce memory cells)
T- Cells
-
Produce antibodies to viruses and cells (provides specific defense, produce memory cells)
B-Cells
-
Destroy bacteria, transplanted cells, and host cells with viral infection or cancer (non-specific)
Natural killer cells
