A metanephric kidney is the functional kidney of adult amniotes, that is, the reptiles, birds, and mammals. It occupies a more caudal position in the body cavity and is a much larger, more compact structure containing many tubules. It is drained by a ureter.

Difference between mesonephric and metanephric kidney?
Mesonephric kidneys are the primitive excretory organs found in fish and amphibians, while metanephric kidneys are the more advanced excretory organs found in mammals, including humans. Metanephric kidneys filter blood to produce urine through nephrons, while mesonephric kidneys mainly function to remove waste products from the blood.

What are the female structures formed for the paramesonephric duct?
The male structures formed from the mesonephric duct are:* ductus epididymis * ductus deferens * ureter * pelvis, calyces, collecting tubules (in the kidneys) * ejaculatory duct * seminal vesicle
What is the function of mesonephric duct?
The mesonephric or wolffian duct is present in young embryos of both genders and develops into the trigone of the urinary bladder. In male embryos, the duct is induced by testosterone, released from the testis, to develop into the epipidymis, vas deferens and seminal vesicles.

What are the trigone?
The trigone is a smooth triangular region of the internal urinary bladder formed by the two ureteral orifices and the internal urethral orifice.The area is very sensitive to expansion and once stretched to a certain degree, the urinary bladder signals the brain of its need to empty. The signals become stronger as the bladder continues to fill.Embryologically, the trigone of the bladder is derived from the caudal end of mesonephric ducts, which is of mesodermal origin (the rest of the bladder isendodermal). In the female the mesonephric ducts regresses, causing the trigone to be less prominent, but still present.
