What mammal has the most long-looped nephrons?
Kangaroo rats have the most long-looped nephrons among mammals. These nephrons help in concentrating urine and conserving water, which is vital for survival in their desert habitats.
What are the different types of nephrons?
There are two main types of nephrons in the kidney: cortical nephrons, which are located primarily in the outer cortex of the kidney, and juxtamedullary nephrons, which are found near the medulla and have longer loops of Henle. Cortical nephrons are more common and are responsible for most of the kidney's filtration, while juxtamedullary nephrons play a key role in the concentration of urine.
3 How do cortical nephrons and juxtamedullary nephrons differ structurally?
The cortical nephrons,from their name are almost entirely embedded within the cortex of the kidney.They have shortish loops of Henle that do not really extend far into the medulla. By contrast, the juxtamedullary nephrons have longs loops of Henle that do extend far into the medulla.The glomeruli of the juxtamedullary nephrons are typically close to the medulla (which is how these got their name)
What is the purpose of the juxtamedullary nephrons?
Juxtamedullary nephrons are positioned close to the medulla of the kidney and play a crucial role in concentrating urine. They have long loop of Henle which allows for the reabsorption of water and solutes, helping the body to maintain water balance and excrete waste efficiently.
What are the filters inside a kidney called?
The filters inside a kidney are called nephrons. Each kidney contains thousands of nephrons, which are responsible for filtering waste and excess substances from the blood to form urine.
Which Nephrons have a long loop of Henle?
Juxtamedullary nephrons have a long loop of Henle, which extends deep into the medulla of the kidney. These nephrons play a crucial role in concentrating urine by creating a hypertonic medullary interstitium through the countercurrent multiplier mechanism.
What mammal has the most long-looped nephrons?
Kangaroo rats have the most long-looped nephrons among mammals. These nephrons help in concentrating urine and conserving water, which is vital for survival in their desert habitats.
What is a tiny filtering unit in the kidney?
The filtering unit of the kidney is the nephrons.

How many nephrons in each kidney?
There are about 1 million nephrons in a kidney. Most humans have 2 kidneys.
Does the cortex contain nephrons?
No, the cortex does not contain nephrons. Nephrons are the functional units of the kidneys and are predominantly located in the renal cortex and renal medulla.
What are nephrons called if they are located mainly in the cortex?
Cortical nephrons are located mainly in the cortex of the kidney. They have shorter loops of Henle that mainly dip into the outer medulla. These nephrons are responsible for most of the kidney's filtration processes.
What is the purpose of the juxtamedullary nephrons?
Juxtamedullary nephrons are positioned close to the medulla of the kidney and play a crucial role in concentrating urine. They have long loop of Henle which allows for the reabsorption of water and solutes, helping the body to maintain water balance and excrete waste efficiently.
Where are the majority of nephrons located?
The majority of nephrons are located in the cortex of the kidney. These cortical nephrons play a crucial role in the filtration and reabsorption of substances from the blood to form urine.
Why are nephrons surrounded by tiny blood vessels?
Why are nephrons surrounded by many tiny blood vessels
Kidneys are made of many that filter water sugar salt and wastes from the blood?
Nephrons are the tiny filters that remove nitrogenous wastes from the blood. Nephrons are found in the kidneys.
