what kind of epithelium lines the urinary bladder
Transitional epithelium
title: Urinary system text: shorter, beginning at the bladder neck and terminating in the vaginal vestibule. Under microscopy, the urinary system is covered in a unique lining called urothelium, a type of transitional epithelium. Unlike the epithelial lining of most organs, transitional epithelium can flatten and distend. Urothelium covers most of the urinary system, including the renal pelvis, ureters, and bladder. The main functions of the urinary system and its components are to Average urine production in adult humans is about 12 litres (L) per day, depending on state of hydration, activity level, environmental factors, weight, and the individual's health. Producing too much or title: Epithelium text: rectum are composed of nonkeratinized stratified squamous epithelium. Other surfaces that separate body cavities from the outside environment are lined by simple squamous, columnar, or pseudostratified epithelial cells. Other epithelial cells line the insides of the lungs, the gastrointestinal tract, the reproductive and urinary tracts, and make up the exocrine and endocrine glands. The outer surface of the cornea is covered with fast-growing, easily regenerated epithelial cells. A specialised form of epithelium – endothelium forms the inner lining of blood vessels and the heart, and is known as vascular endothelium, and lining lymphatic vessels as lymphatic endothelium. Another type, mesothelium, title: Simple columnar epithelium text: Simple columnar epithelium A simple columnar epithelium is a columnar epithelium that is uni-layered. In humans, a simple columnar epithelium lines most organs of the digestive tract including the stomach, small intestine, and large intestine. Simple columnar epithelia line the uterus. Simple columnar epithelium is further divided into two categories: ciliated and non-ciliated. Non-ciliated types are found in the digestive tract. Ciliated types are found within bronchioles of the respiratory tract and in the oviduct of the female reproductive tract. "Ciliated columnar epithelium" moves mucus and other substances via cilia and is found in the upper respiratory tract, the Fallopian title: Transitional epithelium text: Transitional epithelium Transitional epithelium is a type of stratified epithelium – tissue consisting of multiple layers of epithelial cells which can contract and expand as needed. It is so named because of this function in the transition of degree of distension. It has a basement membrane. This tissue structure type is found in urothelium, including that of the renal pelvis, urinary bladder, the ureters, the superior urethra, and the prostatic and ejaculatory ducts of the prostate. The appearance of transitional epithelium depends on the layers in which it resides. Cells of the basal layer are cuboidal, or cube-shaped, and columnar, title: Ureter text: Ureter In human anatomy, the ureters are tubes made of smooth muscle fibers that propel urine from the kidneys to the urinary bladder. In the adult, the ureters are usually long and around in diameter. Histologically, the ureter is lined by the urothelium, a type of transitional epithelium, and has an additional smooth muscle layer in the more distal one-third to assist with peristalsis. In humans, the ureters arise from the pelvis of each kidney, and descend on top of the psoas major muscle to reach the brim of the pelvis. Here, they cross in front of the common iliac
