Kidney has a bean-shaped structure, the kidney is surrounded by tough fibrous tissue, the renal capsule, which is itself surrounded by perinephric fat, renal fascia (of Gerota) and paranephric fat. In the study, the crude aqueous extract of MO Lam, ‘Moringacea’, shows that the weight of an Adult Wistar rats to be insignificantly increased in body weight at the first week of administration which latter dropped little by little doing the weeks of the administration in groups (1, 2,and 3) rats, by comparing (p<0.05) to the control group after MO administration, the Organ (Kidneys) shows a significant difference between the Kidneys (left and right kidneys) after sacrificing the rats in relation to the control group rats. Moringa oleifera (MO) increase the weight of the animals morphologically by comparing the weight of the animals before and after administration. Histological sections shows a normal Glomerulli, Peri-Glomerular Space, Convoluted Tubules, and Interstitium, after administration of the Crude Aqueous Extract of MO lame in terms with the control group rats.
