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”?

slide2

What is “Biology”?

What is “Science”?

slide4

Universe

Subatomic part.

What is “Human”?

Galaxy

Atoms

  • Scientific perspective:Humans are relative to everything else in universe…
    • energy & matter
    • levels of organization

Solar System

Molecules

Planet (Earth)

Organelles

Biosphere

Ecosystem

Community

Population

slide5

At what levels will we study Anatomy & Physiology?

?

  • Studying cells and their structures (____________)
  • Studying characteristics of tissues (______________)
  • Systemic, Regional and Organismal approaches

Cells

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).

slide8

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) -- contractile tissue provides movement

4) -- tissue that allows detection of and response to the environment

Organs

Organism

What are some examples of organs???

slide11

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

M =N =R =R =S =

slide13

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 = _______)

Depends on _________________!!!

slide14

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?

slide15

?

________

2 main situations…

1) Variable is maintained within “+” & “-” limits

?

_______

2) The variable moves away from a “normal” value

?

slide16

Set point

Set point

Comparing the status of the variable prior to and after the response... which one would you classify aspositive feedbackand which one isnegative feedback???

slide17

Check out the Case Study on pg. 9

Be ready to take a quiz and/or discuss this next class period
