Question

question 39 (1 point)
where does the filtrate go from the distal convoluted tubule?
bowmans capsule
proximal convoluted tubule
loop of henle
collecting duct
question 40 (1 point)
what is the result of an increased amount of aldosterone being released from the adrenal cortex?
decreased production of adh
increased blood pressure
vasodilatation
vasoconstriction
increased rate of glycogen breakdown

Explanation:

• Question 39: The filtrate flows from the distal convoluted tubule to the collecting duct. Bowman's capsule is where filtration begins (not the destination from the distal convoluted tubule). The proximal convoluted tubule and loop of Henle come before the distal convoluted tubule in the nephron's flow - sequence.
• Question 40: Aldosterone (from the adrenal cortex) acts on the kidneys to increase sodium re - absorption and potassium excretion. This leads to increased water re - absorption (due to osmosis as sodium is re - absorbed), which in turn increases blood volume. An increase in blood volume leads to increased blood pressure. ADH (antidiuretic hormone) production is not directly decreased by aldosterone. Vasodilatation and vasoconstriction are more directly related to other factors like nitric oxide and angiotensin II respectively. The increased rate of glycogen breakdown is more related to hormones like glucagon.

Answer:

• Question 39: collecting duct
• Question 40: increased blood pressure
