The purpose of this study was to determine the histological structure of the kidney of Pelophylax bedriagae and the distribution of hyaluronic acid (HA) in the kidney tissue. The kidneys of P. bedriagae are long, brown, ribbon-like structures covered with connective tissue. Nephrons, the functional units of the kidney, consist of the renal corpuscle, proximal and distal tubules, collecting tubule, and collecting duct. The renal corpuscle is composed of the glomerulus and Bowman’s capsule. There is no structure similar to Henle’s loop, which is found in higher vertebrates. The visceral layer of Bowman’s capsule is composed of podocytes surrounding the glomerular capillaries. |
