(look for spider web like

tissue location

(Simple Cuboidal Epithelium)

Liver, thyroid, mammary glands, kidney tubules

tissue function

(Simple Cuboidal Epithelium)

Absorption + secretion; produce protective mucous coat; move mucus in the resp tract

tissue type

Simple Cuboidal Epithelium

tissue type

• Look for edge of cells where long cilia can be seen

tissue location

(Pseudostratified columnar epithelial)

Respiratory trach (nasal cavity to bronchi) - trachea

tissue function

(Pseudostratified columnar epithelial)

Secretes and propels mucus in resp tract

tissue type

simple columnar epithelium

• look for Dark short edge of apical surface (brush boarder of microvilli)

• also look for goblet cells

tissue location

(simple columnar epithelium)

GI tract + uterus

tissue function

(simple columnar epithelium)

Absorbtion; secretion of muscus, movement of egg in uterine tube

tissue type

simple squamous epithelium

• flat thin cells

• this is the superior view

• the side view shows them more squished/squamous

tissue location

(simple squamous epithelium)

Alveoli + some kidney tubules

(this photo shows the cells only at the very top layer)

tissue function

(simple squamous epithelium)

Allow rapid diffusion; secrete lubrication serous fluid

tissue type

keratinized stratified epithelium

• Nuclei die off before the surface

• look for large corneum / dead cell top layer

tissue location

(keratinized stratified epithelium)

epidermis / palms and soles

tissue function

(keratinized stratified epithelium)

Resist abrasion and penetration from pathogens; retards water loss through skin

tissue type

non-keratinized stratified squamous epithelium

• Nuclei go all the way to the surface

tissue location

(non-keratinized stratified squamous epithelium)

tongue + esophagus + vagina

tissue function

(non-keratinized stratified squamous epithelium)

Resist abrasion and penetration from pathogens

tissue type

stratified cuboidal epithelium

• Chunks of closely clumped cuboidal cells

• May surround ducts

tissue location

(stratified cuboidal epithelium)

sweat gland duct

tissue function

(stratified cuboidal epithelium)

Contributes to sweat secretion; secretes ovarian hormone; produces sperm

tissue type

Urothelium / transitional epithelium

tissue location

(Urothelium / transitional epithelium)

bladder, urinary tract

tissue function

(Urothelium / transitional epithelium)

Stretches to allow filling of urinary tract , ureter, bladder + part of urethra

tissue type

areolar connective tissue

tissue location

(areolar connective tissue)

Under epithelial + Surrounding blood vessels and trachea

tissue function

(areolar connective tissue)

Loosely binds epithelia to deeper tissues; allows passage of nerves and blood vessels through other tissues (ex. dermal papillae)

tissue type

reticular connective tissue

tissue location

(reticular connective tissue)

bone marrow and spleen

tissue function

(reticular connective tissue)

Forms supportive stroma (framework) for lymphoid organs

tissue type

dense regular connective tissue

tissue location

(dense regular connective tissue)

tendons + ligaments

tissue function

(dense regular connective tissue)

Ligaments tightly bind bones together and resist stress; tendons attach muscle to bone and transfer muscular tension to bones

tissue type

dense irregular connective tissue

tissue location

(dense irregular connective tissue)

dermis of the skin

tissue function

(dense irregular connective tissue)

Withstands stress applied in unpredictable directions; imparts durability to tissues

tissue type

elastic connective tissue

tissue location

(elastic connective tissue)

aorta/artier, lungs, dermis

tissue function

(elastic connective tissue)

allows stretching but returns to normal shape

tissue type

adipose connective tissue

tissue location

(adipose connective tissue)

subcutaneous fat + organ packing

tissue function

(adipose connective tissue)

Energy storage + thermal regulation

tissue type

hyaline cartilage

tissue location

(hyaline cartilage)

trachea and coastal cartilage

tissue function

(hyaline cartilage)

Hold airway open during respiration; precursor of bone in fetal skeleton

tissue type

elastic cartilage

tissue location

(elastic cartilage)

epiglottis - external ear

tissue function

(elastic cartilage)

Provides flexible, elastic support

tissue type

fibrocartilage

tissue location

(fibrocartilage)

menisci + intervertebral disc

tissue function

(fibrocartilage)

Resists compression and absorbs shock in joints

tissue type

bone

tissue location

(bone)

skeleton

tissue function

(bone)

Physical support of body

tissue type

blood

tissue location

(blood)

Heart and blood vessels

tissue function

(blood)

Transports nutrients, gasses, waste, chemical signals, and heat throughout the body.
