"HE GAVE THEM FOR YOUR PURIFICATION AND GOOD HEALTH: PROTECT THOSE AMAZING KIDNEYS"
In the beginning God made the heavens & the earth, plants, animals & man. He endowed man with organs, some single & some in duplicate. Kidneys one of such duplicate organs
The kidneys in the bible are regarded as sacred & were among the organs burnt on the altar of God for peace, sin, trespass offerings, cleansing & purification of the land.
Several references about this role in the books of Exodus & Leviticus.
The major function of the kidneys is excretion of waste products, excess water & formation of urine.
The kidneys are the waste filtering & disposal system of the body, removing body wastes from food eaten & muscle activity, resulting in purification of blood of these waste products & maintenance of a stable internal milieu
To achieve this function, the kidneys have a huge blood supply & gets as much as 25% of the cardiac output
