Question 3
1 / 1 pts
Which of the following is the most direct representation of the efferent pathway in the feedback loop that occurs in response to low blood calcium?
  osteoclast
  osteoblast
  parathyroid gland

Question 4
1 / 1 pts
Given everything we've studied so far in this module, what is the most likely explanation for how a person could have osteoporosis at the same time as having normal blood calcium?
  the body is taking calcium from bones in order to keep blood calcium normal
  the osteoblasts have lost their ability to effectively incorporate calcium into bone
  the parathyroid gland is interfering with Vitamin D's ability to assist in calcium absorption
  the digestive system has become insensitive to Vitamin D
  the osteoclasts are malfunctioning and breaking down bone tissue inappropriately

  Positive Feedback Loop
