Homework Answers
Question 1: What stimulates the secretion of parathyroid hormone from the parathyroid gland?
Answer: B. Low blood calcium level.
Explanation: PTH is secreted in response to low blood serum calcium. To increase low serum Calcium level, PTH(parathyroid hormone) stimulates osteoclast activity within bone to release more ionic calcium into blood .
Question 2: As a result of the general stress response, blood concentrations of epinephrine to
Answer: C. and cortisol rise.
Explanation: In general stress response both Epinephrine and cortisol levels rise.
Epinephrine increases your heart rate, elevates your blood pressure and boosts energy supplies. Cortisol hormone, increases sugars (glucose) in the bloodstream, enhances your brain's use of glucose and increases the availability of substances that repair tissues.
