Quiz 5 - Cell Organization: Tissues and Organs (ppt) Flashcards
cells
- the basic unit of life
two ways cells work
- by themselves (ex: blood cells)
- together as tissues and organs
4 types of tissues
- epithelial
- connective
- muscle
- nervous
function of epitheleal tissue
- interact with the outside world
- deals with things that are outside the body or originated outside the body
function of connective tissue
- holds things together
function of muscle tissue
- allows the body t do work
function of nervous tissue
- allows for rapid communication throughout the body

shapes; sizes
T/F: epithial tissue needs to be replaced frequently
T
what is it that replaces epithelial tissue?

- bone
- fat
function of connective tissue
