Tissues and Cells (3)

simple squamous function

diffusion, filtration

simple squamous location

alveoli, lining of blood vessels, serous membranes

simple cuboidal function

absorption, secretion

simple cuboidal locations

kindey tubulues, glands

simple columnar functions

absorption, secretion movement (if ciliated)

simple columnar locations

lining of the stomach, small intestine
lining of the uterine tubes

stratified squamous functions

protection

stratified squamous locations

epidermis of skin, lining of oral cavity, pharynx, esophagus, anus, vagina

pseudostratified columnar functions

protection, movement (if ciliated)

pseudostratified columnar locations

lining of respiratory tract

transitional functions

distention, relaxation

transitional locations

lining of ureters, bladder, urethra

adipose

stores energy, protects, cushions, and insulates our bodies

areolar

connects epithelial tissue to deeper tissues

dense regular

found in tendons and ligaments

collagen fibers that line up in a parallel fashion

dense irregular

collagen fibers that do not line up parallel

found in the dermis, organ capsules, and periosteum

elastic

found in airways and blood vessles

reticular

found in lymphatic organs and bone marrow

sebaceous (oil) glands

produce sebu, (in other words, it secretes oil) like a white head

sudoriferous glands, 2 types

merocrine glands and apocrine gland

merocrine gland

most numerous

produce watery sweat

glands package their secretions in secretory vesicles.

apocrine gland

axillary, nipple, anal, and genital areas (reason why your armpits smell but not your arms!)

produce viscous sweat

holocrine gland

Sebaceous glands

found in hair follicles, lead to zits

death/ruptures cells

lanugo hair

fetal hair

vellus hair

fine hair on most of the body

terminal hair

head, armpit pubic region, male facial hair

dermis 2 layers

papillary layer, reticular layer

papillary layer

areolar connective tissue

reticular layer

dense irregular connective tissue

hypodermis (2 types of connective tissue)

areolar and adipose CT

anagen

hair actively grows

catagen

transition phase, follicle shrinks

telogen phase

follicle is inactive, hair stops growing and is shed
