what are the cuaes of hypentions
sodium homestic effect 0- kidnesya are unable to excrete aproat amount of sodium for given blood pressure
heridy defects of smooth mulse lining arterioles
what is teh effect of age on blood pressure
higher blood presure in elder, thus need to be watched and treated
where is the closest genetic cordation in a family, parents or sibling
sibling
