- Your stomach starts grumbling during your Anatomy and Physiology lecture. As soon as class is over, you decide to hit the snack area. You see your favorite candy bar in one of the snack machines and you cannot resist. Your blood glucose level before eating this snack is 90mg/100ml (normal). As you digest and then absorb the sugar in the candy, the level of glucose in your blood increases to 120mg/100ml. The increased level of glucose is detected by receptors on pancreatic beta cells. These receptors send a signal into the beta cells, informing them of the excessive glucose in the blood. The pancreatic beta cells release insulin. The insulin travels through the blood and stimulates the liver and body cells. The liver andbodycellsremovetheextra glucosefromtheblood,reducingyourbloodglucosebackto its original level of 90mg/100ml. At this point, release of insulin stops.1. Whatisthestimulusofthiscontrolloop?2. Whatisthecontrolcenter?3. Whatistheeffector?4. In this feedback mechanism,…The body loses water by way of the ________. a. skin b. lungs c. digestive system d. urinary system e. both c and d f. a through dFigure 33.21 State whether each of the following processes are regulated by a positive feedback loop or a negative feedback loop. A person feels satiated after eating a large meal. The blood has plenty of red blood cells. As a result, erythropoietin, a hormone that stimulates the production of new red blood cells, is no longer released from the kidney.

- Mr. Gregory comes to the doctor with high blood pressure. Tests show that he also has elevated levels of renin in his blood and atherosclerotic plaques that have nearly blocked blood flow through his renal arteries. Mr. Gregory is puzzled. Explain to him how decreased blood flow in his renal arteries could cause. renin secretion to increase. Map the pathways through which elevated renin causes high blood pressure for Mr. Gregory.An athlete is sweating profusely but does not rehydrate. The changing conditions are detected by osmoreceptors in the hypothalamus. Select the conditions associated with loss of water and the response it triggers. 1. Increased solute concentration 2. Decreased solute concentration 3. Increased blood volume 4. Decreased blood volume 5. Increased blood pressure 6. Decreased blood pressure 7. Increased release of ADH 8. Decreased release of ADH Record your answers in ascending (lowest to highest) order.please explain how body will maintain homeostasis with osmoregulation, like in the picture
