|---|---|
| where is the simple squamous located? (4) | alveoli of the lungs, lines blood and lymph nodes, body cavities found in diffusion and filtration |
| where is simple cuboidal located (3) | kidney tubules, covers ovaries, lines ducts of some glands |
| simple cuboidal functions | urine formation in kidneys, and glandular secretions |
| simple columnar location (ciliated-2 and nonciliated-6) | nonciliated: uterus, stomach, and intestines- protect underlying tissues, secret digestive fluids, absorb nutrients. ciliated: uterine tubes and help move egg cells towards uterus |

| blood location | throughout the body within a closed system of blood vessels and heart chambers |
| skeletal muscle tissue function | voluntary movements of skeletal parts |
| skeletal muscle tissue location | head, trunk, limbs, muscles attached to bones (striated) |
| smooth muscle tissue function | involuntary movements of internal organs (lacks striations) |
| cardiac muscle tissue function | contraction for heart beats (striated) |
| plasma membrane | defines the outer shell of a cell |
| mitochondria | organelles in the cytoplasm that make ATP "the power house of the cell" |
| ribosome | very large enzymes that make polypeptides |
| rough ER | essential for producing and processing proteins required for cell function and secretion |
| golgi apparatus | collects, modifies, and pocket substances manufactured by the cell |
| smooth ER | essential for lipid production, lacks ribosomes, calcium regulation, metabolic processing that supports diverse cellular activities across tissues |
| lysosome | breaks down worn out organelles, debris, and large ingested particles within the cell |
| nucleus | the control center of the cell, contains the cell's DNA and is bounded by a membrane |
