|
simple squamous epithelium
|
alveoli (air sacs in lungs); inner lining (endothelium) of heart and blood vessels; serous membranes of stomach, intestines, and some other viscera; surface mesothelium of pleura, pericardium, peritoneum, and mesenteries
|
|
|
stratified squamous epithelium (keratinized)
|
palms, heels, epidermis
Resists abrasion and penetration by pathogenic organisms, retards water loss through skin |
|
|
stratified squamous epithelium (nonkeratinized)
|
vagina, anal canal, tongue, esophagus, oral mucosa
Resists abrasion and penetration by pathogenic organisms |
|
|
Simple cuboidal epithelium
|
Liver, thyroid, mammary, salivary, and other glands; most kidney tubules; bronchioles
Absorption and secretion; production of protective mucous coat; movement of respiratory mucus |
|
|
Stratified cubiodal epithelium
|
Sweat gland ducts; egg-producing vesicles (follicles) of ovaries; sperm-producing ducts (seminiferous tubules) of testis
Contributes to sweat secretion; secretes ovarian hormones; produces sperm |
|
|
Simple columnar epithelium
|
Inner lining of stomach, intestines, gallbladder, uterus, and uterine tubes; some kidney tubules
Absorption; secretion of mucus and other products; movement of egg and embryo in uterine tube May contain goblet cells Ciliated in some organs; brush border of microvilli |
|
|
Pseudostratified columnar epithelium
|
Respiratory tract from nasal cavity to bronchi; portions of male urethra
Secretes and propels mucus May contain goblet cells Often ciliated |
|
|
Transitional epithelium
|
Urinary tract—part of kidney, ureter, bladder, part of urethra; allantoic duct in umbilical cord
Stretches to allow filling of urinary tract Resembles stratified squamous epithelium, but surface cells are rounded, not flattened, and often bulge at surface. When distended cells are flat, when relaxed, cells bulge. Some cells have two nuclei |
