Susie participates in BPCC's blood drive. Afterward, her red blood cell count is low and her she is slightly dehydrated. Her brain tells her bone marrow to produce more red blood cells and her kidneys to conserve water. Susie’s bone marrow and kidneys are acting as what part of the homeostatic system?

Jamie has fallen ill. Her body temperature has risen to high levels. Her blood pressure is high and her glucose level is low. In order for her body to return to homeostasis and for Jamie to feel better, the following events are taking place: Select all that apply Dilating blood vessels reduce blood pressure Lowering her body temperature by sweating Raise her body temperature by sweating Apply positive feedback to restore glucose levels in the blood stream by using the hormone glucagon which will raise blood sugar Apply negative feedback to restore glucose levels in the blood stream by using the hormone glucagon which will raise blood sugar Constricting blood vessels to increase blood pressure
Figure 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.

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.

A male has lost blood as a result of a gunshot wound. Even though thebleeding has been stopped, his blood pressure is low and dropping,and his heart rate is elevated. Following a blood transfusion, his bloodpressure increases and his heart rate decreases. Which of the following statement(s) is (are) consistent with these observations?a. Negative-feedback mechanisms can be inadequate without medical intervention.b. The transfusion interrupted a positive-feedback mechanism.c. The increased heart rate after the gunshot wound and before thetransfusion is a result of a positive-feedback mechanism.d. a and be. a, b, and c
At Kate's next appointment, Paula showed Kate how to use a glucose meter. She instructed Kate to measure her blood glucose level twice a day before and after breakfast and dinner. Paula explains to Kate that her pre-meal blood glucose level should be 110 mg/dLmg/dL or less, and if it increases by more than 50 mg/dLmg/dL, she needs to lower the amount of carbohydrates she consumes. Kate and Paula proceed to plan several meals. Because a meal should contain about 45 to 60 gg of carbohydrates, they combined fruits and vegetables that have high and low levels of carbohydrates in the same meal to stay within the recommended range. Kate and Paula also discuss the fact that complex carbohydrates in the body take longer to break down into glucose and, therefore, raise the blood sugar level more gradually. Kate increased her exercise to walking 30 minutes twice a day. She began to change her diet by eating 6 small meals a day consisting of more fruits and vegetables without starch such as green…
Bob is sitting outside on a warm day and is sweating pro- fusely. His friend Mary wants to practice taking blood pres- sures, and he agrees to play patient. Mary finds that Bob’s blood pressure is elevated, even though he is resting and has lost fluid from sweating. (She reasons that fluid loss should lower blood volume and, thus, blood pressure.) Mary asks you why Bob’s blood pressure is high instead of low. What should you tell her?
