Cortical néphrons vs juxta medulair nephron

Thread starter fordi1
Start date Sep 25, 2015

In summary, there are two types of nephrons in the kidney: cortical nephrons and juxta medullary nephrons. Cortical nephrons are located in the outer cortex of the kidney and make up the majority of nephrons. They are responsible for filtering blood, reabsorbing important nutrients, and producing urine. Juxta medullary nephrons, on the other hand, are located near the medulla of the kidney and have longer loops of Henle, allowing for better water conservation and regulation of blood pressure. Both types of nephrons play important roles in maintaining the body's fluid and electrolyte balance.

Can someone help me to understand why juxta medulair néphron is implied in génération of cortico papilar gradient

By "why" are you asking for experimental evidence?

What is the difference between cortical nephrons and juxta medullary nephrons?

Cortical nephrons are located in the outer region of the kidney and have a shorter loop of Henle, while juxta medullary nephrons are located near the medulla and have a longer loop of Henle. This difference allows for different functions and roles in kidney filtration and urine concentration.

Which type of nephron is more abundant in the kidney?

Cortical nephrons make up about 80-85% of the total nephrons in the kidney, while juxta medullary nephrons make up the remaining 15-20%. This difference in abundance is due to the different functions and contributions of each type of nephron to kidney function.

How do cortical and juxta medullary nephrons differ in their filtration capabilities?

Cortical nephrons have a higher glomerular filtration rate (GFR) compared to juxta medullary nephrons, meaning they are more efficient in filtering blood and producing urine. Juxta medullary nephrons, on the other hand, have a higher concentration ability and are responsible for producing concentrated urine through the process of countercurrent multiplication in the loop of Henle.

What are some other key differences between cortical and juxta medullary nephrons?

In addition to differences in location, loop of Henle length, and filtration capabilities, cortical and juxta medullary nephrons also have different blood supply. Cortical nephrons receive blood from the peritubular capillaries, while juxta medullary nephrons receive blood from the vasa recta. This difference in blood supply also contributes to their different functions in the kidney.

Do cortical and juxta medullary nephrons work together or separately in kidney function?

Both cortical and juxta medullary nephrons work together to maintain overall kidney function. While they have different roles and contributions, they are interconnected and rely on each other to maintain homeostasis and regulate body fluid balance. Disruption or dysfunction in one type of nephron can affect the function of the other and overall kidney function.
