metenephric is M E T A nephric whereas mesonephric is M E S O nephric.
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.
They have froggy kidneys
The difference is in the origins of the tissue. There are 3 parts of an embryonic kidney: 1.pronephros (anterior portion) 2.mesonephros (middle portion) 3.metanephros (posterior portion) Opisthonephric kidneys are made up of the mesonephros and metanephros. An Opisthonephric kidney is divided into two parts: 1) proximate 2)distal Example --> Mudpuppies have opisthonephric kidneys Metanephric kidneys are made up of only the metanephros. A Metanephric kidney is divided into three parts: 1)proximate 2)intermediate (ex. the Loop of Henle forms from this part) 3)distal Example --> Pigeons have metanephric kidneys
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 kidneys are above the large and small intestine and there is the diaphragm above it
Bovine kidneys are larger and have a smooth surface, while sheep kidneys are smaller and have a lobulated surface. Bovine kidneys have longer renal papillae compared to sheep kidneys. Sheep kidneys have a more triangular shape compared to the more elongated shape of bovine kidneys.
The ear and kidney have a similar shape
Between the kidneys and the bladder, same as in the male.
diffusion
Kidneys are retroperitoneal and so lie between the peritoneum and the abdominal wall, in the retroperitoneal space (a part of the abdominal cavity).
The teamwork between the kidneys and urinary bladder is an example of a coordinated organ system working together to regulate fluid balance in the body. The kidneys filter waste and excess substances from the blood to form urine, which is then stored in the bladder until it is expelled from the body.
