The middle layer of the bladder consists of a network of smooth muscle fibres and outside this layer is a thin sheet of connective tissue covered externally by the peritoneum. Blood comes to glomeruli from afferent arterioles which have a wider lumen then the capillaries so that the blood in glomeruli is under high pressure which causes filtration of blood.

The later metamorphosis of the tadpole to frog has also been studied for hormonal controls and limb development. Since the excretory and reproductive systems are closely associated, hence, it is customary to call the two systems together as a urogenital or urinogenital system, though both are unrelated functionally. %PDF-1.7 Content Guidelines 2.
