For 1a. I got an answer but Im not sure what the other questions are asking about specfically. what am i missing... or im just not understanding the rest of the questions(1b-1d)...

1a).On a daily basis our body needs eight 8-ounce glasses of water which is almost 3 quarts. The kidneys regulate water by saving water when dehydration occurs and filtering out urine. We lose water through our skin by sweating. As water leaves our body through multiple ways it eventually is removed from blood plasma. This causes the blood to become more concentrated and then the physiological sensory receptors in the hypothalamus are triggered. This allows the dehydrated person to release antidiuretic hormone (ADH) through the posterior pituitary gland. The ADH allows the kidneys to function properly by diluting the blood plasma and recuperate water from the urine. Our body conserves water via the nervous system to the salivary glands in the mouth.

More than sixty percent of a human body is water. When people need water, they feel thirsty. Refer to the related lectures and other resources to answer the followed questions with cited reference in details 1a. Where and how the thirst signals are generated (why people feel thirsty? 5 points) 1b. where and how the thirst signals are detected (how people sense thirsty? 4 points) 1c. where and how the thirst signals are processed (how people know thirsty? 5 points) 1d. what's the outcomes of thirst signal processing (what people do after feeling thirsty? 6 points)
