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

Why study tissues?

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

What general types of tissues are there?

What are some examples of organs???

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 = _______)

Depends on _________________!!!

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?

How feedback loops maintain homeostasis?

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???
