ABSTRACT

Morphological characteristics of the kidneys in the two-humped camels were investigated using the anatomical and histological methods. The 2 kidneys in the camel contributed about 0.6% of the body weight. The ratio of thickness of the renal medulla to the cortex was 4:1, which indicated that Henle’s loops in camel’s kidneys were very long. In cortex, there were more juxtamedullary nephrons and mid-cortical nephrons which had longer Henle’s loops. Proximal convoluted tubules were far longer than the distal ones. In the outer medullary zone, the vasa recta were grouped obviously into specific vascular bundles which alternated with the bundles of Henle’s loops and collecting tubules. The inner medullary zone was thicker than the outer one. Specialised fornices were formed by projecting of either side of the pelvis and extended between renal pyramids to medullary outer zone where second pyramids clearly occurred. The characteristics above showed that kidneys in bactrian camels possessed a strong reabsorption and hence promoting the production of high concentrated urine.
