Question
Chapter 49, Problem 14TYU
Summary Introduction
To propose: A hypothesis to explain how a receptor for aldosterone appears to have evolved much earlier than aldosterone itself.
Introduction: The endocrine system is the chemical signaling system that uses blood vessels as information channels. The endocrine glands are ductless organs located within the organ systems and contain groups of endocrine cells that secrete their hormones directly into their surroundings.
Hypothesis: The receptor for aldosterone might bind with another similar hormone in early times that no longer exist.

3. After eating food, the concentration of glucose in the blood
increased, which caused the secretion of a hormone that
normalized the concentration of glucose.
A. Name this hormone, where is it made?
B. Draw a diagram of the regulation of the release of this
hormone. What is an adjustable parameter?
C. Can there be a hormone concentration in the scheme as a
RP. If so, show it in outline?
D. Could it be that the concentration of the hormone in the
blood was increased, but this would not lead to the
normalization of the concentration of glucose in the blood, which
remained above normal, and this would lead to the appearance
of glucose in the urine and an increase in daily diuresis.
E. Name the possible causes of a violation in the circuit of
regulation of hormone secretion.
