A	Positive Feedback Response
B	Negative Feedback Loop

Explanation:

Detailed explanation-1: -When the body is low in water, the pituitary gland secretes vasopressin (also called antidiuretic hormone) into the bloodstream. Vasopressin stimulates the kidneys to conserve water and excrete less urine.

Detailed explanation-2: -When you’re dehydrated, you lose blood volume, which causes your blood to get thicker. That makes it harder for your heart to supply that blood to your muscles. As your heart works harder to pump that blood, your heart rate increases.

Detailed explanation-3: -Urine volume will increase leading to dehydration and a fall in blood pressure.

Detailed explanation-4: -One way the the kidneys can directly control the volume of bodily fluids is by the amount of water excreted in the urine. Either the kidneys can conserve water by producing urine that is concentrated relative to plasma, or they can rid the body of excess water by producing urine that is dilute relative to plasma.
