What effect does the binding of proton to hemoglobin have on its function?
Give this one a try later!
it decreases hemoglobin's affinity for oxygen
Based on a manual calculation of a hematocrit for someone that is dehydrated, would
the person appear to be anemic or polycythemic?
Give this one a try later!
polycythemic
What hormones stimulate erythropoiesis?
,Give this one a try later!
-erythropoietin
-testosterone
-growth hormone
-thyroid hormone
What vessels does the right ventricle pump blood into?
Give this one a try later!
-into the pulmonary trunk, which leads to the pulmonary arteries
compare and contrast sickle-cell trait and sickle-cell disease
Give this one a try later!
-trait, you are a carrier for the disease and you are heterozygous for the
allele (HgbAS)
-disease, you are homozygous for the allele (HgbSS)
-disease life expectancy is 40-50 years
-only treatment is blood transfusion or bone marrow transplant
What is the major hormone that stimulates erythropoiesis?
,Give this one a try later!
-erythropoietin (EPO)
-JG apparatus cells secrete this hormone in the kidney
-hormone is secreted under hypoxic conditions
How would baroreflex respond to acute bout of hypotension or hypertension?
Give this one a try later!
-Hypotension, there would be an increase sympathetic activity to the heart
and vasculature, and a reduction in parasympathetic activity to the heart
-hypertension, would decrease sympathetic activity to the heart and
vasculature and an increase in parasympathetic activity to the heart.
Where is the binding site for oxygen on hemoglobin?
Give this one a try later!
to the iron
What blood types can AB- receive?
Give this one a try later!
, A-, B-, AB-, O-
How are cardiac output and total peripheral resistance pharmacologically modulated
to lower mean arterial pressure?
Give this one a try later!
-CO is modulated by beta blockers to reduce the CO by weakening the
pump
-TPR is modulated by alpha blockers to reduce TPR by vasodilating blood
vessels
What are the 2 main components of heme?
Give this one a try later!
-porphyrin rings and ferrous iron
What are the different methods that individuals employ for blood doping?
Give this one a try later!
-testosterone and EPO are used for blood doping
-they can also take blood out their own body and then reinject it
