decrease decrease If the clearance of a small positively charged molecule is greater than zero, but less than the GFR, you should suspect that the substance must be: filtered and reabsorbed Kidney dialysis is an important clinical tool but it is not as good as a normal kidney function because: the blood levels of waste products vary greatly between sessions The intracellular fluid water compartment of the body accounts for about: 40% of total body weight What best describes the kidney's overall function? the kidneys are the main excretory organ, their function is to maintain overall body fluid homeostasis by stabilizing the composition of the ECF The kidneys: regulate acid-base balance, reabsorb electrolytes and water, regulate arterial blood pressure/plasma volume Vasoconstriction of only the afferent arteriole would result in: a decrease in glomerular capillary hydrostatic pressure In a healthy individual, glucose is typically found in the urine when: the transport maximum is smaller than the amount filtered The segment of the nephron where the tubular fluid is the most concentrated is the: tip of the loop of Henle in the juxtamedullary nephron What statement about the loop of Henle is true? the ascending limb is impermeable to water When the mean arterial blood pressure goes down from 110mmHg to 70mmHg, you expect the efferent arteriole to vasoconstrict If you are over-hydrated and the highest osmolarity in the renal medulla is 900mOsm, you expect: the secretion of ADH to be low and the urine to be hypo-osmotic If you are de-hyrdate and the osmolarity in the renal medulla is 1000mOsm, you expect the urine osmolarity to be close to the osmolarity of the fluid in the: tip of the Loop of Henle If a person quickly drinks a gallon of distill water, you expect the plasma osmolarity will initially _ and then the secretion of ADH will _.
