Organic Chemistry/Carboxylic acids. < Organic Chemistry. A carboxylic acid is characterized by the presence of the carboxyl group -COOH. The chemical reactivity of carboxylic acids is dominated by the very positive carbon, and the resonance stabilization that is possible should the group lose a proton.
The presence of renal tubule cells in the urine is of diagnostic significance, as it points towards an underlying kidney disease. The last type of epithelial cells are squamous cells. These cells are the largest cells seen in urine specimens. These cells are flat, usually with an angular or irregular outline.
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.
