Human Health and Disease SCIE 254
Week 4 Assignment
Petechiae is the occurrence of tiny, pinpoint hemorrhages in the skin. An ecchymoses is a
large area of hemorrhage into the skin. Hematocrit is the ratio of the volume of red blood cells to
the total volume of blood. A reticulocyte is an immature red blood cell without a nucleus, having
a granular or reticulated appearance when suitably stained. Stem cells are undifferentiated cells
of a multicellular organism which is capable of giving rise to indefinitely more cells of the same
type, and from which certain other kinds of cell arise by differentiation. An amyloid is a protein
produced in a variety of diseases but commonly with increasing age. Epistaxis is a simple
nosebleed. Hematuria is blood in the urine. Hematochezia is when you have blood in your fecal
matter. A hematoma is a localized collection of blood that like a bruise. Virchow’s triad is a
endothelial cell injury. DIC is a condition in which damage to endothelial cells causes
widespread activation of the clotting cascade with subsequent formation of microthrombi in
small vessels.
Anemia is defined as a decrease in the circulating red blood cell mass. The major
categories of anemia are iron-deficiency anemia resulting from dietary deficiency, and iron-
deficiency anemia resulting from chronic bleeding, for example from the uterus or
gastrointestinal tract. “A complete blood count measures hemoglobin and mean corpuscular
volume. Hemoglobin of less than 13 grams per deciliter for men and less than 12 for women is
diagnostic of anemia” (Iron-Deficiency Anemia | NHLBI, NIH, 2019). “In anemia, a decrease in
the number of RBCs transporting oxygen and carbon dioxide impairs the body's ability for gas
exchange. The decrease may result from blood loss, increased destruction of RBCs (hemolysis),
or decreased production of RBCs.” (Maakaron, 2021).
