Epigastric región Hypogastric region

A patient previously had abdominal surgery and has a scar from a transverse (cross) section.

Which of the following is an example of a homeostatic imbalance

being sick with the flu

Blood calcium levels are maintained by a negative feedback homeostatic mechanism. When blood calcium levels rise beyond their set point, a hormone called calcitonin is released by the thyroid gland to a lower blood calcium levels back to their set point. What role does the thyroid gland play in this mechanism

Effector
