Question

How many nephrons are in one kidney?

Answer 1

Human kidneys are two bean-shaped organs located behind the peritoneum in the abdominal region and their main function is the removal of waste from the human body.

Complete answer:
1)Nephron is known as the basic structural and functional unit of the kidney. An adult human has more than 1 million nephrons in one kidney. There are no fixed numbers of nephrons in humans and their numbers given by different sources and researchers also vary. Hence we can consider an average value that is around 1 million.

2)The nephron is made up of two structures that are the renal corpuscle and the renal tubule. The renal corpuscle contains the bowman's capsule and the glomerulus and the renal tubule is made up of proximal convoluted tubule, Henle's loop, distal convoluted tubule, and collecting duct. The proximal convoluted tubule and distal convoluted tubule lies in the renal cortex but the henle's loop drops down to the renal medullary region. The Henle's loop is also made up of two parts that are known as ascending limb and descending limb.

Note: Do not get confused between the two terms that are nephron and neuron. The nephron is known as the basic structural and the functional unit of the kidney that is required for the excretion of waste products from the human body whereas the neuron is the basic unit of the nervous system. The right kidney in humans is located slightly lower than the left kidney.
