ANSWERS ALREADY GRADED A PLUS
GUARANTEED PASS
◉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
◉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
◉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
◉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
