Please help Anatomy and phys 1. Compare and contrast positive and negative feedback loops of the endocrine system. Provide a specific example of each, including which gland is responsible for the hormone related to that loop. 2. What is the difference between endocrine and exocrine glands in terms of both form and function? Why is one type not considered part of the endocrine system? 3. Describe the cascade of events that occurs when blood glucose levels decline, including which organ and cells respond, which hormones are released, and how the process helps maintain homeostasis. Your answer should cover all three ways glucose is re-introduced to the body. What is the ultimate use of the glucose created in this process? 4. Why can both type I and type II diabetes, untreated, result in impaired vision or blindness as someone ages? How does type II diabetes turn into type I diabetes as someone ages? 5. Imagine you have a patient who has come to you and is exhibiting symptoms such as fatigue and increased thirst and urination. What would you check for to determine whether the patient has Cushings, type I diabetes, or type II diabetes?
