What is a function of the mammalian kidney?

Answer 1

The same as ours. The kidney is an organ that takes in a large volume of blood each day (think many times your total blood volume), filters it, and then reabsorbs the vast majority of the water and solutes. This reabsorbed matter then goes right back into the bloodstream, while the little that remains is excreted as urine. So in short, a pig's kidneys filter its blood and regulate levels of water and solutes in the blood stream, creating urine out of what's left over.
Pigs kidneys like all kidneys in animals & humans are filtering organs for excretion of waste such as salts,urea,waste cells,toxic material ,water etc

It is eaten as meat diet by some humans & carnivourous animals. pigs kidneys have high fat .
to filter blood for waste.

Answer 2

A pig's heart does the same thing as a human heart. It circulates blood and brings oxygen to the pig's cells.

Answer 3

The kidneys are the filters for all mammals' blood. Blood is pumped through the kidneys, and all of the waste and extra water is filtered out of the blood and become urine.

Answer 4
