Abstract This work was carried out to investigate the structure of the camel’s kidney and its accommodation with the surrounding hard environment of the desert. This investigation was done on 6 kidneys of adult one-humped male camels (Camelus dromedarius) of apparently healthy ones with 7-9 years old. Each samples was examined by both light and electron microscopy (TEM and SEM). Light microscopical samples were taken from 7 pieces of each kidney. Electron microscopical samples were taken from both cortex and medulla of each kidney. The obtained results revealed the following: Capsule and interstitial tissue The capsule of camel’s kidney is thick consisting of two layers, the outer one is very thick and the inner one is much thinner. The cortical and medullary inter stitium are characterized by presence of intertubular cells with two main types, fibroblast and mononuclear cell. Renal corpuscle The renal corpuscles are mainly spherical in shape. The parietal layer of Bowman’s capsule is lined by simple squamous epithelium which sometimes possesses a single cilium extending into the Bowman’s space and also some short microvilli. These squamous cells rest on a very thick basal lamina which contains vacuoles and very electron dense granules. |
