Transitional epithelium is a type of tissue that changes shape in response to stretching (stretchable epithelium). The transitional epithelium usually appears cuboidal when relaxed and squamous when stretched. [1] This tissue consists of multiple layers of epithelial cells which can contract and expand in order to adapt to the degree of ...
When viewed under a microscope, the bladder can be seen to have an inner lining (called epithelium), three layers of muscle fibres, and an outer adventitia. [ 8 ] The inner wall of the bladder is called urothelium , a type of transitional epithelium formed by three to six layers of cells; the cells may become more cuboidal or flatter depending ...
The ureter is lined by urothelium, a type of transitional epithelium that is capable of responding to stretches in the ureters. The transitional epithelium may appear as a layer of column-shaped cells when relaxed, and of flatter cells when distended. Below the epithelium sits the lamina propria. The lamina propria is made up of loose ...

Cuboidal epithelium has cells whose height and width are approximately the same (cube shaped). Columnar epithelium has cells taller than they are wide (column-shaped). Endothelium refers to cells that line the interior surface of blood vessels and lymphatic vessels , [ 1 ] forming an interface between circulating blood or lymph in the lumen and ...
The collecting duct system of the kidney consists of a series of tubules and ducts that physically connect nephrons to a minor calyx or directly to the renal pelvis.The collecting duct participates in electrolyte and fluid balance through reabsorption and excretion, processes regulated by the hormones aldosterone and vasopressin (antidiuretic hormone).
