1. What general type of feedback loop is this?
Option a. This is actually no feedback here
Option b. Negative feedback loop
Option c. Neutral feedback loop
Option d. Positive feedback loop
Option e. Anticipatory feedback loop
2. In the feedback system shown above, what determines the set point?
Option a. The salt content of the blood
Option b. The amount of pressure on the wall of the heart
Option c. The set point is directly determined by the amount of urine in the bladder
Option d. There is no set point because it is positive feedback loop
Option e. The set point is determined the amount of natriuretic peptide in the blood
Option f. The kidneys
3. How is increased urine production likely to reduce blood volume
Option a. Urine production reduces the number of blood cells produced by the bone marrow
Option b. Increased urine production remove water from the blood, reducing blood volume
Option c. Increased urine production induces a reduction in water absorb from the gut
Option d. Decreased salt levels stimulate blood processing by the spleen
