The kidneys have a higher blood flow than even the brain, liver or heart.
The kidneys reabsorb and redistribute 99% of the blood volume and only 0.1% of the blood filtered becomes urine.
Each kidney is about 4½ inches (11.4 cm) long.
Each kidney weighs approximately 170gms and is the size of your fist.
The kidneys of a newborn baby are about 3X larger in proportion to body weight as in the adult.
The volume of urine excreted daily varies from 1000 to 2000 ml (averaging 1500 ml).
What year was the first successful kidney transplant? (1954 with identical twins in the US)
Your kidneys represent about 0.5% of the total weight of the body, but receive 20–25% of the total arterial blood pumped by the heart.
Your kidneys receive about 56 litres of blood per hour.
Over 1.8 litres of recycled blood is pumped through your kidneys every day.
Each kidney contains approximately one million nephrons
Placed end to end, the nephrons of one kidney would stretch about 8 km
