Difference between Cortical Nephron and Juxtamedullary Nephron

A nephron is a structural and functional unit of the kidney. The two main types of nephrons are cortical nephrons and juxtamedullary nephrons. Each type has a distinct location within the kidney and performs a different function.

What is Cortical Nephron?

The cortical nephron is the most common type of nephron in the mammalian kidney. It is characterized by its location in the renal cortex, as well as by its short length. The renal cortex is the outermost layer of the kidney, and the cortical nephrons make up about 80% of all nephrons in the kidney.

Cortical nephrons are shorter than other types of nephrons, such as juxtamedullary nephrons, which are found in the renal medulla. The shorter length of the cortical nephron allows for a more rapid filtration of blood, and as a result, these nephrons play a crucial role in the removal of waste products from the body.

In addition to their shorter length, cortical nephrons also have a larger diameter than other types of nephrons. This allows for a greater surface area for filtration, and as a result, these nephrons are more efficient at removing waste products from the blood. Cortical nephrons are also responsible for regulating extracellular fluid volume and electrolyte levels in the body.

What is Juxtamedullary Nephron?

Juxtamedullary nephrons are a type of kidney cell that is located near the medulla, or innermost layer, of the kidney. Juxtamedullary nephrons play an important role in the filtration of blood and the excretion of waste products. The Juxtamedullary nephrons are able to remove small molecules, such as urea, from the blood. They are also able to reabsorb larger molecules, such as amino acids and glucose, from the filtrate.

The Juxtamedullary nephrons play an important role in regulating the body’s fluid balance and electrolyte levels. Juxtamedullary nephrons are also responsible for producing renin, a hormone that helps to regulate blood pressure.

Difference between Cortical Nephron and Juxtamedullary Nephron

The nephrons are the functional units of the kidney that filter blood and produce urine. There are two types of nephrons cortical nephrons and juxtamedullary nephrons that differ in their location within the kidney. Cortical nephrons are located in the cortex, or outer layer, of the kidney. Juxtamedullary nephrons are located in the medulla, or inner layer, of the kidney.

The primary difference between these two types of nephrons is the length of their renal corpuscles. Renal corpuscles are composed of a glomerulus a cluster of blood vessels surrounded by a Bowman’s capsule. The glomerulus filters blood, and the Bowman’s capsule collects filtered fluid to be further processed into urine. Cortical nephrons have shorter renal corpuscles than juxtamedullary nephrons.

Conclusion

The cortical nephron is the more common type of nephron in adult humans. It is found in the renal cortex and is responsible for tubular secretion, reabsorption, and urine formation. The juxtamedullary nephron is a less common type of nephron that is found in the renal medulla. This nephron has a larger Bowman’s space and is responsible for concentrating urine.
