BIOL 235 Exam Questions and Answers
Latest Updated | Graded A+.
Erythrocytes contain the enzyme - (ANSWER)carbonic anhydrase
carbonic anhydrase catalyzes - (ANSWER)the conversion of metabolically
produced C)2 and water into carbonic acid
fixed phagocytic macrophages - (ANSWER)remove most old erythrocytes from
circulation
Location of fixed phagocytic macrophages - (ANSWER)narrow capillaries of the
spleen
Undifferentiated cells called pluripotent stem cells reside - (ANSWER)in the bone
marrow
pluripotent stem cells - (ANSWER)continuously divide and develop myeloid stem
cells and lymphoid stem cells to give rise to each of the types of blood cells
emigration or diapedesis - (ANSWER)The process of leukocytes squeezing
through the capillary endothelium to exit the vasculature
agglutinins - (ANSWER)genetically-determined glycoprotein and glycolipid
antigens found on the surface of an erythrocyte
,2
ESV - (ANSWER)volume of blood in the ventricle after ejection has been
completed
Increase in ESV when - (ANSWER)stroke volume is decreased
Three cations with important effect on heart function - (ANSWER)K+, Ca2+, and
Na+
Increased blood levels of NA+ - (ANSWER)blocks Ca2+ inflow and decreases force
of contraction
Excess in K+ - (ANSWER)blocks generation of action potentials
pharynx - (ANSWER)serves as a sound resonating chamber, contains tonsils,
directs air flow inferiorly
larynx - (ANSWER)passes air form pharynx into windpipe, site of sound
production
paranasal sinuses - (ANSWER)resonates sound, not part of the pharynx
fauces - (ANSWER)opening from oral cavity into pharynx
,3
tertiary bronchus - (ANSWER)carries air to a segment of a lung
terminal bronchiole - (ANSWER)carries air directly into a respiratory bronchiole
pleural membranes - (ANSWER)surround the lungs
surfactant - (ANSWER)reduces surface tension at sites of gas exchange
alveoli - (ANSWER)actual sites of gas exchange
eupnea - (ANSWER)normal, quiet breathing
costal breathing - (ANSWER)shallow breathing using just the external intercostal
muscles
compliance - (ANSWER)amount of effort required to expand the lungs and chest
wall
inspiratory capacity - (ANSWER)tidal volume + inspiratory reserve volume, usually
about 3600 mL in males
, 4
vital capacity - (ANSWER)tidal volume + inspiratory reserve volume + expiratory
reserve volume; usually about 4800 mL in males
functional residual capacity - (ANSWER)residual volume + expiratory reserve
volume; usually about 2400 mL in males
Henry's law - (ANSWER)states that the amount of gas that will dissolve in a liquid
is proportional to the partial pressure of that gas and its solubility
Bohr effect - (ANSWER)when pH decreases, O2 saturation of hemoglobin
decreases
Dalton's law - (ANSWER)each gas in a mixture of gases exerts its own partial
pressure
medulla oblongata - (ANSWER)sets basic rhythm of breathing
pons - (ANSWER)includes the pontine respiratory group
Blood is - (ANSWER)a connective tissue that consists of blood plasma (liquid) plus
formed elements (red blood cells, white blood cells, and platelets)
Whole blood - (ANSWER)blood plasma and formed elements
