Skin has three layers: 1  The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. 2  The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. 3  The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
The parietal epithelium of Bowman's Capsule is a layer of simple squamous epithelium lining the outer border of the corpuscle. The visceral epithelium of Bowman's capsule (or podocytes) surrounds the capillary endothelial cells, with mesangial cells filling in the spaces between closely apposed capillaries.ach nephron drains into a collecting tubule, which serves as a duct system to conduct the urine out of the Kidney. The glomeruli and the proximal and distal convoluted tubules are found in the cortex. The descending loop of Henle leaves the cortex and enters the medulla, returning to the cortex as the ascending loop.
