They have froggy kidneys
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.
metenephric is M E T A nephric whereas mesonephric is M E S O nephric.
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
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.
it is bigger than that of the female because it serves two functions: passage of urine and sperm....(unlike in female)
The organ was called a kidney first. The kidney bean is called so because it is shaped like a kidney, the organ.
An accessory kidney is an "extra" kidney.
Kidney stones. Kidney failure.
A person who donates a kidney is called a living kidney donor.
Kidney failure and kidney rejection can still remain after kidney transplant.
An opisthonephric kidney is the functional kidney of anamniotes, fish, and amphibians.
