BIOL 235 final Exam Questions and
Answers 100% Pass
Erythrocytes contain the enzyme - ✔✔carbonic anhydrase
carbonic anhydrase catalyzes - ✔✔the conversion of metabolically
produced C)2 and water into carbonic acid
fixed phagocytic macrophages - ✔✔remove most old erythrocytes from
circulation
Location of fixed phagocytic macrophages - ✔✔narrow capillaries of the
spleen
Undifferentiated cells called pluripotent stem cells reside - ✔✔in the bone
marrow
pluripotent stem cells - ✔✔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 - ✔✔The process of leukocytes squeezing through
the capillary endothelium to exit the vasculature
agglutinins - ✔✔genetically-determined glycoprotein and glycolipid
antigens found on the surface of an erythrocyte
ESV - ✔✔volume of blood in the ventricle after ejection has been completed
Increase in ESV when - ✔✔stroke volume is decreased
Three cations with important effect on heart function - ✔✔K+, Ca2+, and
Na+
Increased blood levels of NA+ - ✔✔blocks Ca2+ inflow and decreases force
of contraction
Excess in K+ - ✔✔blocks generation of action potentials
pharynx - ✔✔serves as a sound resonating chamber, contains tonsils,
directs air flow inferiorly
larynx - ✔✔passes air form pharynx into windpipe, site of sound
production
2

,paranasal sinuses - ✔✔resonates sound, not part of the pharynx
fauces - ✔✔opening from oral cavity into pharynx
tertiary bronchus - ✔✔carries air to a segment of a lung
terminal bronchiole - ✔✔carries air directly into a respiratory bronchiole
pleural membranes - ✔✔surround the lungs
surfactant - ✔✔reduces surface tension at sites of gas exchange
alveoli - ✔✔actual sites of gas exchange
eupnea - ✔✔normal, quiet breathing
costal breathing - ✔✔shallow breathing using just the external intercostal
muscles
compliance - ✔✔amount of effort required to expand the lungs and chest
wall
inspiratory capacity - ✔✔tidal volume + inspiratory reserve volume,
usually about 3600 mL in males
3
100% Pass Guarantee Katelyn Whitman, All Rights
, vital capacity - ✔✔tidal volume + inspiratory reserve volume + expiratory
reserve volume; usually about 4800 mL in males
functional residual capacity - ✔✔residual volume + expiratory reserve
volume; usually about 2400 mL in males
Henry's law - ✔✔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 - ✔✔when pH decreases, O2 saturation of hemoglobin
decreases
Dalton's law - ✔✔each gas in a mixture of gases exerts its own partial
pressure
medulla oblongata - ✔✔sets basic rhythm of breathing
pons - ✔✔includes the pontine respiratory group
Blood is - ✔✔a connective tissue that consists of blood plasma (liquid) plus
formed elements (red blood cells, white blood cells, and platelets)
Whole blood - ✔✔blood plasma and formed elements
