BIOL 2010 Human Anatomy & Physiology I
Romans 12:4 “For as in one body we have
many members, and all the members do not
have the same function,”
So what is “Anatomy” and “Physiology”?
What is “Biology”?
What is “Science”?
What is “Life”?

•
What is “Human”?
Universe
Subatomic part.
Galaxy
Scientific perspective:
Humans are relative to
everything else in
universe…
Atoms
Solar System
Molecules
Planet (Earth)
Organelles
•energy & matter
Biosphere
•levels of organization
Ecosystem
Community
Population
At what levels will we study Anatomy &
Physiology?
?
• Studying cells and their
structures (____________)
• Studying characteristics of
tissues (______________)
• Systemic, Regional and
Organismal approaches

Why study cells?
Cells are the basic unit of
life. Cells are comprised of
various organelles.

Why study tissues?
Tissues are comprised of
groups of cells working
together for a specific
task(s).

What general types of tissues are there?
We classify them into 4 types:
1)
-- this tissue is the external and
internal lining of our bodies and many organs.
2)
-- this tissue is diverse in form and
function and is found throughout the body.
3)
movement
-- contractile tissue provides
4)
-- tissue that allows detection of
and response to the environment
What are some examples of organs???
Cells

Just as ______ unite to form ________… tissues
function together to form __________!
?

?
Just as cells unite to form tissues… and tissues
function together to form organs… organs function
together for specific tasks and become organ
systems!

How do all of these tissues, organs and
systems function together to keep you alive?
This state of equilibrium or balance is
called …
(homeo = _____ & stasis = _______)

_________________!!!
How feedback loops maintain homeostasis?
Feedback mechanisms regulate one or more
variables and often consist of 3 components:
1) _____________ What are their function?
2) _____________ What function?
3) _____________ How about their function?
2 main situations…
1) Variable is maintained within “+” & “-”
limits
?
?
_______
2) The variable moves away from a
“normal” value
?
________
Comparing the status of the variable prior to and after the
response... which one would you classify as positive
feedback and which one is negative feedback???
