epithelial tissue

Simple Squamous Epithelium Function

diffusion, osmosis & filtration - exchanges gases - covers surfaces

Simple Squamous Epithelium Location

lines air sacs of lungs

Simple Cubodial Epithelium Function

Secretion & absorption

Simple Cubodial Epithelium Location

glands and ducts, surface of ovaries

Simple Columnar Epithelium Function

Absorbtion, secretion, and protection

Simple Columnar Epithelium Location

Lining of uterus, form mucous membranes

Pseudostratified Columnar Epithelium Location

lines the respiratory tract

Pseudostratified Columnar Epithelium Function

Absorption and secretion, protection, move mucus

Stratified Squamous Location

skin and areas with friction

Stratified Squamous Function

best for protection

Transitional Epithelium Function

Distensibility, forms barrier

Transitional Epithelium Location

lines interior urinary bladder

Glandular Epithelium Function

makes & releases secretions

Glandular Epithelium Location

glands - 2 types: endocrine & exocrine

Goblet Cell

Secrete Mucus - cup shaped

Keratinization

hardening of the skin for protection

Apocrine Glands

Lose small portions of their cells bodies during secretion

Stratified

2 or more layers

Mucus

Protective, thick fluid release by cells

Microvilli

Small Extentions - increase surface area for more absorption

Holocrine Glands

Entire cell lyses during secretion

Merocrine Glands

Release fluid through exocytosis ; most abundant

Simple

single layer

Cilia

extends from free surface & move constantly - sweeps substances to new location

Endocrine Glands

ductless- secretion hormones

Exocrine Glands

Have ducts- secretions exit to epithelial surface

Serous Fluid

watery fluid w/ high conc. of enzymes - lubricates

Sebaceous Fluid

Oil released into skin that keeps skin soft and waterproof

Epithelial Tissue Characteristic

Cells are tightly packed, lack blood vessels (avascular)

Epithelial Tissue Function

Protection, secretion, excretion, absorption

Connective Tissue Characteristic

Cells connect to each other & other body parts, good blood supply, binds supprorts, protects, fill space

Connective Tissue Function

Produce blood cells, store fat

Muscle Tissue Characteristic

Able to contract in response to stimuli

Muscle Tissue Function

Movement

Nervous Tissue Characteristic

Integration, regulation, sensory reception

Nervous Tissue Function

Transmit impulses for coordination
