One of the least complicated of the endocrine control systems directly responds to changing blood levels of ions and nutrients. Which of the following describes this mechanism?
A) neural stimulation
B) catabolic inhibition
C) humoral stimulation
D) protein synthesis

Question

Quizplus · Accepted Answer

This mechanism is called humoral stimulation, which refers to the regulation of hormone secretion in response to changes in blood levels of certain ions and nutrients. For example, when blood glucose levels increase, the pancreas secretes insulin to promote glucose uptake into cells and decrease blood glucose levels. This type of regulation is relatively simple and does not involve neural or protein synthesis pathways.
