How long is the human small intestine?
Small intestine
The length of the small intestine can vary greatly, from as short as 2.75m (9.0ft) to as long as 10.49m (34.4ft), also depending on the measuring technique used.[3] The typical length in a living person is 3m-5m.[4][5] The length depends both on how tall the person is and how the length is measured.[3] Taller people generally have a longer small intestine and measurements are generally longer after death and when the bowel is empty.[3]
Kidney
The kidneys are two bean-shaped organs found in vertebrates. They are located on the left and right in the retroperitoneal space, and in adult humans are about 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.
