Intro to Anatomy
Ch. 35-1

I.

Organization of the Human Body (Review)
A. Cells: Basic unit of structure and function
B. Tissues: Group of cells that perform a single fxn
 4 types: epithelial, connective, nervous, muscle

 What are these tissues’ functions?
C. Organs: Different types of tissues that work together
to perform a closely related function (e.g. eye, liver)
D. Organ Systems: Group of organs that perform
closely related function
(e.g. circulatory, respiratory, digestive)

II.

Human Organ Systems Overview

A. Nervous System
1. Structures: Brain, spinal cord, peripheral nerves
2. Function: Recognizes and coordinates the body’s
response to changes in its internal and external
environments

 All 11 systems work together to maintain homeostasis

III. Homeostasis
A. Definition: the process by which organisms keep internal
conditions relatively constant despite changes in their
external environments.
B. Requires the integration of all organ systems at the same
time
C. Nervous system in conjunction with the endocrine system
(hormones) is responsible for this integration
D. Homeostasis is maintained by feedback inhibition
(negative feedback)
1.

Your body’s response results in decreasing the effect of the
stimulus

Brain slows down
cellular activity

Body temp. rises

This feedback inhibits the production
of chemicals that speed up cellular
activity and keeps the body from
getting too hot.
