STANDARD 9: As a result of the coordinated structures and
functions of organ
systems, the internal environment of the human body remains
stable (homeostatic) despite changes in the outside environment.
As a basis
for understanding this concept:
9a: The complementary activity of major body systems provides
oxygen and nutrients and removes toxic waste products such as
9b: The nervous system mediates communication between different
parts of the
body and the body's interactions with the environment.
9c: Feedback loops in the nervous and endocrine systems regulate
in the body.
9d: The functions of the nervous system and the role of neurons
transmitting electrochemical impulses.
9e: The roles of sensory neurons, interneurons, and motor neurons
sensation, thought, and response.
*9f: The individual functions and sites of secretion of digestive
(amylases, proteases, nucleases, lipases), stomach acid, and bile
*9g: The homeostatic role of the kidneys in the removal of
wastes and the role of the liver in blood detoxification and
*9h: The cellular and molecular basis of muscle contraction,
roles of actin, myosin, Ca+2 , and ATP.
*9i Hormones (including digestive, reproductive, osmoregulatory)
internal feedback mechanisms for homeostasis at the cellular
level and in
