Homeostatic Loops

Mr. Andersen explains how humans use feedback loops to maintain homeostasis, focusing on temperature, blood glucose, and blood calcium regulation. He describes the role of receptors and effectors in these processes, using examples like the hypothalamus for temperature control, the pancreas for glucose regulation, and the thyroid for calcium balance.

How do feedback loops contribute to maintaining homeostasis in the body?

What happens to blood calcium levels when they are too high?

Discuss the role of calcitonin in calcium homeostasis.
