- What is the function of the hormone erythropoietin? a. stimulates production of red blood cells b. stimulates muscle growth c. causes the fight-or-flight response d. causes testosterone productionarrow_forwardThe hormone insulin enhances the transport of glucose (sugar) from the blood into most body cells. Its secretion is controlled by a negative-feedback system between the concentration of glucose in the blood and the insulin-secreting cells. Therefore, which of the following statements is correct? A decrease in blood glucose concentration stimulates insulin secretion, which in turn further towers blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn lowers blood glucose concentration. A decrease in blood glucose concentration stimulates insulin secretion, which in turn increases blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn further increases blood glucose concentration. None of the preceding is correct.arrow_forwardFigure 16.14 Goiter, a disease caused by iodine deficiency, results in the inability of the thyroid gland to form T3 and T4 . The body typically attempts to compensate by producing greater amounts of TSH. Which of the following symptoms would you expect goiter to cause? a. Hypothyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. b. Hyperthyroidism, resulting in weight loss, profuse sweating and increased heart rate. C. Hyperthyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. d. Hypothyroidism, resulting in weight loss, profuse sweating and increased heart rate.arrow_forward
- Which of the following hormone regulates BMR? A. Insulin B. Leptin C. Calcitonin D. Thyroid hormonesarrow_forwardDraw a negative feedback loop for blood calcium regulation. Falling calcium level signals release of parathyroid hormone from the parathyroid glands. Calcium is released from bones, increased uptake by digestive system. Rising calcium level signals release of calcitonin from the thyroid. Blood calcium is taken up into bone tissue.arrow_forwardExplain how you would interpret the graph in Figure to show that PTH and calcitonin act in a complementary way to control blood calcium level.arrow_forward
- A scientist hypothesizes that the pancreas’s hormone production is controlled by neural stimuli. Which observation would support this hypothesis? a. Insulin is produced in response to sudden stress without a rise in blood glucose. b. Insulin is produced in response to a rise in glucagon levels. c. Beta cells express epinephrine receptors. d. Insulin is produced in response to a rise in blood glucose in the brain.arrow_forwardA hormone called calcitonin, produced by the thyroid gland, is released in response to increased levels of calcium ions in the blood. If this hormone acts through negative feedback, what effect will its release have on blood calcium levels?arrow_forwardBlood samples from a young woman named Michelle indicate an elevated blood glucose level. This homeostatic imbalance is most likely caused by an insufficient amount of, or decreased sensitivity to, which hormone? a. growth hormone b. glucagon c. insulin d. cortisolarrow_forward
- Which of the following statements is true about diabetes? a. It can only be inherited. b. Very few people in the world get the condition. c. It is a result of a mismatch between our evolved bodies and our modern lifestyle. d. Once a person is diagnosed with diabetes, the condition rarely progresses.arrow_forwardHormones released by endocrine glands 1) ACTH 2) Cortisol 3) Thyroxine 4) Aldosterone 5) Epinephrine 6) ADH. Match the following to the number above a) ________: returns the sodium ion concentration in the blood back to normal after sweating. b) ________: Decreased secretion leads to an excessive amount of urine. c) _________: Stimulates the release of the hormone responsible for increases in blood sugar. d) ________: Excessive secretion leads to weight loss.arrow_forwardBoth the _____ are involved in the synthesis of calcitriol and erythropoietin. a. anterior and posterior pituitary b. thyroid gland and thymus c. liver and kidneys d. parathyroids and pancreatic islets e. epidermis and liverarrow_forward
