what is the normal size of the human kidney
Kidney In adult males, the kidney weighs between 125 and 170 grams. In females the weight of the kidney is between 115 and 155 grams.[7] A Danish study measured the median renal length to be 11.2 cm (4.4 in) on the left side and 10.9 cm (4.3 in) on the right side in adults. Median renal volumes were 146 cm3 on the left and 134 cm3 on the right.[8]
Urinary system The first step in urine formation is the filtration of blood in the kidneys. In a healthy human the kidney receives between 12 and 30% of cardiac output, but it averages about 20% or about 1.25 L/min.
Kidney The kidneys are two bean-shaped organs found on the left and right sides of the body in vertebrates. They are located at the back of the abdominal cavity in the retroperitoneal space. In adults they are about 11 centimetres (4.3Â in) in length. They receive blood from the paired renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter, a tube that carries excreted urine to the bladder.
Fluid balance These outputs are in balance with the input of ~2500 ml/day.[9]
