Cells |
-fundamental unit of structure and function in all living things -smallest unit of matter that is alive -all cells come from pre-existing cells |
|
|
Tissue |
-a group of cells working together to perform some function -4 basic types: •epithelial tissue •connective tissue •muscular tissue •nervous tissue |
|
|
Organ |
-a group of tissues working together to perform some complex function |
|
|
Organ System |
-a group of organs working together to perform some highly complex activity |
|
|
Organism |
-organ system working together finally |
|
|
Epithelial Tissue |
-absorb, transport, excretes, protects, and contains nerve cells for resperation -simple epithelium- 1 cell layer thick -stratified epithelium- more than 1 layer thick |
|
|
Simple Squamous Epithelium Location: frog skin, lining of cheek, etc. Function: allows passage of materials through diffusion and filtration |
|
|
Simple Cuboidal Epithelium
Location: kidney tubules, etc (cube shape) Function: secretion and absorption |
|
|
Simple Columnar Epithelium (columns) Location: lines the digestive tract, etc. Function: absorption and enzyme secretion |
|
|
Stratified Squamous Epithelium Location: lines the esophagus Function: protects tissues from abrasion |
|
|
Connective Tissues |
-support and bind |
|
|
Connective Cartilage Tissues Location: entire skeleton of shark, outer ear, etc. Function: support and renforcement -chondrocyte: cell -nucleus -lacunae: jelly around nucleus -intercellular matrix: jelly around outside of cell
|
|
|
Connective Bone Tissues Location: bony skeleton Function: support, protection, stores calcium and fat, forms blood cells, etc. -osteocyte: cell -canaliculus: transportation (thin lines coming off of cell) -lucanae: house the cell (jelly around it) -osteon: the whole circle (all the rings) -osteonic canal: big opening |
|
|
Connective Tissues: Blood Location: within arteries and veins of mammals, etc. Function: transport oxygen, carbon dioxide, nutrients, waste, minerals, etc. |
|
|
Connective Adipose Tissues (fat) Location: around kidneys, under skin, within abdomen, etc. Function: energy, insulation, support and protect organs |
|
|
Muscular Tissues |
-allows for movement |
|
|
Skeletal Muscular Tissue -voluntary: we can control it -nucleus on side, squished, elongated nucleus |
|
|
Smooth Muscular Tissue -involuntary: we can't control, no lines, no columns, no cubes |
|
|
Cardiac Muscular Tissue -involuntary: we can't control -intercalated disks- speration between cells |
|
|
Nervous Tissue |
-conducts -neuron -dendrite -cell body -nucleus -cytoplasm -axon |
