Diabetes Type I is a disease directly related to the endocrine system. Which of the following are correct about Type I diabetes? a) It is sometimes also called juvenile diabetes b) Most often it is caused by obesity c) Patiets have insufficient insulin levels d) Both A and C are correct

The basic functional unit of the mammalian kidney is the nephron. It functions to filter the blood. secrete specific solutes. reabsorbs specific solutes. All of the above are functions of the nephron.

Antidiuretic hormone (ADH) is important in maintaining homeostasis in mammals. ADH is released from the hypothalamus in response to high tissue osmolarity. In response to ADH, the collecting duct and distal tubule in the kidney become more permeable to water, which increases water reabsorption into the capillaries. The amount of hormone released is controlled by a negative feedback loop. Based on the model presented, which of the following statements expresses the proper relationship between osmolarity, ADH release, and urine production? (A) As tissue osmolarity rises, more ADH is released, causing less water to be excreted as urine. (B) As tissue osmolarity rises, less ADH is released, causing less water to be excreted as urine. (C) As tissue osmolarity rises, more ADH is released, causing more water to be excreted as urine. (D) As tissue osmolarity rises, less ADH is released, causing more water to be excreted as urine.
