    What is the kidney tubule’s response to a rise in blood pH?
    A rise in blood pH means it is getting more alkaline. That is there is too much bicarbonate in the blood. To counter this, some bicarbonate ions are secreted into the filtrate, while some hydronium ions are absorbed from the filtrate into the tubule cells.

    If the glomerular filtration rate is too high, the macula densa sends a message to the afferent arteriole. What is the effect of this message?
    Constricting the afferent arteriole will decrease the rate of flow of blood into the glomerulus. This will decrease the GFR.

    Which one of the following correctly lists the organs of the renal system?
    There are two ureters (one from each kidney) and one urethra from the bladder to the outside. The prostate is not part of the renal system and is present in males only.

    Four sections of the vasculature of the kidney tubule are listed below. Which one lists them in correct order of blood flow from left to right?
    The afferent arteriole carries blood into the glomerulus so must be first.

    The nephrons of the kidney consist of:
    The nephron includes the glomerulus and renal tubule. The later includes the Bowman’s capsule. Choice D is best even though Bowman’s capsule is not listed.

    One way to increase the glomerular filtration rate is to dilate:
    Dilating the afferent arteriole increases the volume of blood flowing into the glomerulus, while constricting the efferent arteriole decreases the volume of blood leaving the glomerulus. This means water and solutes must leave the glomerulus and enter the Bowman’s capsule, that is, GFR increases.

    Which type of antihypertensive drug aims to prevent vasoconstriction?
    The contraction of smooth muscle causes vasoconstriction. Calcium is necessary for muscle contraction. A Ca channel blocker prevents Ca from entering the cytoplasm, and so it prevents vasoconstriction.
