tissues and systems A+P ch.4 lecture 1
Cell form tissues
tissues form organs
organs form systems
formed when there's a collection of similar cells that act together to perform a function.
4 main types
single layer, same type of cell
looks stratified but it's not
sheet-like structures found throughout body that perform special functions.
can be classified as organs
main organ of your skin, largest visible organ
two layered membrane
lines the walls of the cavities in which organs live in
produces serous fluid- produces friction between tissues and organs.
wraps around individual organ
produces serous fluid that reduces friction between tissues and organs
lines opening to outside world (digestive tract, respiratory system, urinary and reproductive tracts)
most common type of tissue, found scattered throughout body
found in organs, bones, nerves, muscles, membranes, and skin
holds things together and provides structure and support
found in space between bone joints and produces slippery substance called synovial fluid
