Kidney
Bowman’s Capsule | inner layer of cuboidal cells (podocytes) and outer layer of simple squamous epithelium
Loop of Henle | descending – simple squamous epithelium, ascending – simple cuboidal epithelium
Collecting Tubules | simple cuboidal epithelium
Papillary Ducts (Ducts of Bellini) | simple columnar epithelium
Kidney
Renal Corpuscle
Loop of Henle
The Loop of Henle is located in the renal medulla. It is composed of the thick descending and ascending limbs (lined by simple cuboidal epithelium), and the thin descending and ascending limbs (lined by simple squamous epithelium).
Collecting Tubules
The collecting tubules tend to be wider and less regular in shape in comparison to the ascending and descending limbs of the loop of Henle. They are also lined by simple cuboidal epithelium.

Epithelium | transitional epithelium
NO Muscularis Mucosae
2. Submucosa
Connective Tissue | dense irregular connective tissue
3. Muscularis Externa
Loosely arranged layers of smooth muscle and elastic fibres
Inner longitudinal, outer circular, and outermost longitudinal
