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

  1. Who are you? :) And what are you talking about?
    I saw your comment at janeywan, and liked it.
    I had an insight last week, where i realized we humans can thrive anywhere. Can we? Here in my garden i was looking at the fireweed, how it has grown 4 feet in two months, where as in this Northern climate other plants are still less than an inch an most don't even try, they thrive elswhere in the world. But here we are humans...... plant us anywhere and it's up to us....
