Tissues of the human body
Simple cuboidal epithelium
Structure a single layer of cube-shaped cells with a round, centered nucleus Distribution covers surfaces of ovaries lines kidney tubercules and smaller ducts from many glands Function secretion and obsorption
Transitional epithelium or urothelium
Structure cells can appear flat, cube, or round shaped depending on the state it is in Distribution lines urinary bladder, ureters, a portion of the urethra Function allows urinary organs to stretch while holding fluid without rupturing, serves as a protective lining
Stratified columnar epithelium
Structure mixed short and long-shaped cells in columns Distribution lines part of the urethra, excretory ducts of esophageal glands, areas in the anal mucous membrane Function protection and secretion
Simple columnar epithelium
Structure nonciliated and ciliated - a single layer of column cells with oval nuclei Distribution nonciliated- lines digestive canal, gland ducts, gallbladder ciliated- bronchioles, uterus Function remove mucus/foreign particles towards the throat to cough out or spit out, move egg to uterus, secretion, and absorption
Pseudostratifiede columnar epithelium
Structure nonciliated and ciliated false impression of multi-layered cells Distribution nonciliated- lines epididymis, urethra in males ciliated- lines airways of the upper respiratory tract (trachea) Function secretes mucus to trap foreign particles and sweep's it away to eliminate it from the body, absorption and secretion
Stratified cuboidal epithelium
Structure two or more layers of cube-shaped cells Distribution ducts of adult sweat glands, esophageal glands, salivary glands Function protection, limited secretion and obsorption
Stratified squamous epithelium
Structure two or more layers of slightly compacted cells Distribution nonkeratinized- forms the moist lining of the esophagus, mouth, and vagina; keratinized type forms the epidermis of the skin, a dry membrane Keratinized- forms a superficial layer of skin Function protects underlying tissues in areas subject to abrasion, water loss, and forms the first line of defense
nervous tissue
carries information from one part of the body to another
connective tissue
connects, supports, and protects organs. Distributes blood vessels to other tissues
muscular tissue
contracts to make body parts move and generates heat
epithelial tissue
covers the body surfaces; lines hollow organs, cavities, and forms glands
simple squamous epithelium
structure: - single layer of flat cells with oval shaped nucleus distribution: - lines the cardiovascular and lymphatic system (heart, blood vessels, lymphatic vessels) - mesothelium, pulmonary alveoli, eardrum function: - filtration, secretion, diffusion (not found in areas subjected to mechanical strain)
hematolymphoid complex
type of connective tissue (specifically blood and lymph tissue)
