MCB 246 Exam 1 Questions With Complete Solutions
Agglutination Correct Answers clumping of red blood cells that
indicates presence of an antigen
Agranulocytes Correct Answers lymphocytes, monocytes
-A group of leukocytes without granules in their nuclei
Anemia Correct Answers Reduced O2-carry capacity - most
common blood disorder in US caused by low hemoglobin or low
RBC count
Causes: genetics, diet, sex-related differences
Antibodies Correct Answers proteins produced in the plasma to
fight against antigens
Antigens Correct Answers surface proteins on RBCs that
determine blood type & the type of antibodies that will be
produced in the plasma
Aorta Correct Answers The large arterial trunk that delivers
oxygenated blood to systemic circuit to be distributed by arteries
Are globins in RBCs recycled and for what? Correct Answers
Globin proteins are broken down & amino acids are reused for
erythropoiesis
Arterial anastomoses ("widowmaker") in left coronary artery
Correct Answers interconnections between arteries which helps
stabilize coronary blood flow despite pressure differences
between left and right coronary arteries
, arteries are oxygenated or deoxygenated Correct Answers
oxygenated
Arteries transport blood to/away from the heart? Correct
Answers AWAY
AV valves function Correct Answers UNIDIRECTIONAL-
allow blood to flow from the atria to the ventricles
-close when ventricles CONTRACTS
Basophils characteristics Correct Answers Nucleus is bilobed;
Cytosol contains deep blue-violet granules
Basophils function Correct Answers release histamine &
heparin during inflammatory reactions
Capillaries function Correct Answers Serve as site of exchange
either between blood & alveoli of lungs or between blood &
systemic cells
Cardiac fibrous skeleton function Correct Answers Electrically
insulates ventricular cells from atrial cells & serves as anchor
points for attachment of cardiac muscles
Centrifugation Correct Answers Separates hematocrit & plasma
using high speed spinning
Coronary (circuit) circulation Correct Answers supplies blood
to myocardium; provides heart with O2 (heart does not use O2
in blood inside the chambers)
