UNR Biology 224 Exam 1 (Hollander) Questions With
Complete Solutions
100% Filled = Correct Answers End-diastolic volume (EDV) of
blood in the ventricles
A and B blood type are Correct Answers Glycolipids (antigens)
Abundance of RBC's-Hematocrit Correct Answers Slightly less
than half the blood volume (45% average)
99.9% formed elements
4-6 million per microliter of blood
Action potential in a single cell Correct Answers Starts at -90
then depolarizes to around +30 mV and reaches plateau to let
Ca2+ inside. Once contract probe is reaches at 0 mV then
repolarization occurs and K+ leaves the cell
Albumins Correct Answers 60% of plasma proteins
Responsible for viscosity and osmotic pressure of blood
An allergic reaction requires... Correct Answers An anti-
histamine
Androgens Correct Answers Male sex hormones (99.9%
testosterone)
Anemia Correct Answers Lack of a normal number of red blood
cells
, Antibodies Correct Answers Specialized proteins that aid in
destroying infectious agents
At the start of cardiac cycle, atria and ventricles have blood
received during diastole. What is the percent within the
ventricles? Correct Answers ~70%
Atrial Fibrillation Correct Answers Rapid, random, ineffective
contractions of the atrium
Atrial systole pushes blood into the ventricle, filling the
ventricles to what percent? Correct Answers 100%
Atrioventricular (AV) node Correct Answers Conducts
electrical signal across atrial-ventricular septum
Average EDV mL in an adult Correct Answers ~130 mL
Average liters of blood in adult Correct Answers 5-6 liters
Average liters of blood in child Correct Answers 4-5 liters
B-cells Correct Answers Produce antibodies
Basophil Correct Answers -Less than 1% of circulating WBC
-Cross capillary endothelium and accumulate in damaged tissues
-Release Histamines and Heparin
Blood doping Correct Answers Inject extra red blood cells
before competition to improve performance
