BIOL252 Module 1 Review
Describe the shape of erythrocytes. - ANS-Biconcave discs
Describe the viscosity of blood. - ANS-Blood is viscous, barely sticky, and approximately five
times thicker than water.
How do erythrocytes circulate thru narrow capillaries? - ANS-They are flexible and can squeeze
thru small spaces
How do leukocytes vary from erythrocytes? - ANS-They are larger, fewer, have nuclei and
organelles, and shorter lifespans.
How does blood viscosity have an effect on stream? - ANS-Increased viscosity increases
resistance, affecting blood go with the flow and blood stress.
How does liver disease affect clotting? - ANS-Reduces clotting element production.
How does the biconcave shape benefit RBCs? - ANS-Increases surface location for gas
alternate
How is hemolytic sickness of the newborn avoided? - ANS-Rh immunoglobulin remedy
How long do RBCs live? - ANS-About 120 days
How many RBCs are produced in step with 2d? - ANS-Over 2 million per second.
Name the agranular leukocytes. - ANS-Lymphocytes and monocytes
Name the granular leukocytes. - ANS-Neutrophils, eosinophils, basophils
What are not unusual symptoms of anemia? - ANS-Fatigue, cognitive impairment, shortness of
breath, extended contamination risk.
What are Standard Precautions? - ANS-Treat all blood as doubtlessly infectious.
What are the 3 coagulation pathways? - ANS-Intrinsic, extrinsic, and common
What are the 3 formed elements of blood? - ANS-Erythrocytes (RBCs), leukocytes (WBCs), and
platelets.
, What are the three principal anemia classes? - ANS-Insufficient erythrocytes, low hemoglobin
be counted, atypical hemoglobin.
What are the three essential functions of blood? - ANS-Transportation, defense, and
maintenance of homeostasis
What are the 3 primary plasma proteins? - ANS-Albumin, globulins, and fibrinogen
What are the three ranges of hemostasis? - ANS-Vascular spasm, platelet plug formation,
coagulation.
What are the two leukocyte classes? - ANS-Granular and agranular
What reasons agglutination? - ANS-Antibody binding to incompatible antigens
What reasons thrombosis? - ANS-Excessive clot formation in blood vessels.
What determines Rh-wonderful vs Rh-terrible? - ANS-Presence or absence of the D antigen.
What do lymphoid stem cells produce? - ANS-Lymphocytes
What do monocytes become in tissues? - ANS-Macrophages
What do myeloid stem cells produce? - ANS-RBCs, platelets, and granular leukocytes
What do neutrophils do? - ANS-Phagocytose micro organism; growth in acute infections
What does a CBC degree? - ANS-RBCs, WBCs, hemoglobin, hematocrit, platelets.
What does hypochromic imply? - ANS-RBCs have reduced hemoglobin content.
What does normochromic imply? - ANS-RBCs have regular hemoglobin content.
What offers urine and feces their coloration? - ANS-Urobilins (urine) and stercobilin (feces)
What happens throughout platelet plug formation? - ANS-Platelets adhere to collagen and
launch chemical compounds.
What takes place to hemoglobin after RBC breakdown? - ANS-Iron is recycled, amino acids
reused, heme converted to bilirubin.
What hormone regulates erythropoiesis? - ANS-Erythropoietin (EPO)
What is a blood smear used for? - ANS-Examining cellular size, shape, and kind.
