Types of Membranous Epithelial Tissue

Simple squamous epithelium

single layer of flat, scale like cells

Function: allows for ready diffusion/filtration because of thinness

Location: Alveoli and lining of blood/lymphatic vessels

Simple cuboidal epithelium

single layer of cube like cells

Function: secretes and absorb

Location:ducts and tubules of many organs, including the kidneys

Simple columnar epithelium

single layer of columnar cells

Function: participates in absorption and secret mucus by goblet cells

Location: lines the intestines

Pseudostratified columnar epithelium

single layer of irregularly shaped columnar cells with different heights with nuclei a the different levels makes it appear stratified

Function: protect and secretes mucus

Location: lines trachea, large bronchium and nasal mucosa

Stratified squamous epithelium

contains multiple cells layer and most widespread epithelium in the body

Function: resists abrasion and penetration by pathogens and contain kertain

Location: epidermis of skin, esophagus, and vagina

Transitional epithelium

consists of multiple cell layers when stretched, cell layers decrease and cell shape changes from cuboidal to squamous

Function: stretches to allow filling of urinary tract

Location: urinary tract
