Why the loop of nephron of camels are deeper and longer?
These nephron are found with henle’s loop. The juxtamedullary nephron is around 35 \% which is more than human being 15\%. The principle function of henle’s loop is to remove the sodium chloride and water. Hence loop of nephron of camel are deeper and longer.
What is special about kidney in camel?
The camel does have a special kidney and a special GI tract. The camel’s kidney actually can concentrate the urine more than sea water but less than a dessert rat. Since the camel can concentrate the urine more than sea water, salty water intake won’t harm the animal.
How do desert animals benefit from having a longer loop of Henle in their nephrons?
The longer the loop of Henle relative to the overall depth of the cortex, the higher is the osmolarity of the fluid in the bend. The kidney thereby retains as much water as possible, minimising loss of water during water shortage.
How are desert animals adapted to water conservation through the kidney?
To save water ordinarily lost in excretion, another common desert adaptation in animals is dry feces and concentrated urine. Other animals, including lizards, snakes, insects and birds, excrete uric acid, rather than liquid urine.
How are nephrons different in desert animals?
Desert mammals do not readily find water, hence they must excrete very less amount of water. They are able to produce highly concentrated urine. From the accompanying diagram you would be able to see that the Henle’s loop of juxtamedullary ( =adjacent to medulla of kidney) nephron goes deep down into the medulla.
Which nephron structure is only found in birds and mammals?
Juxtamedullary nephrons are found only in birds and mammals, and have a specific location: medullary refers to the renal medulla, while juxta (Latin: near) refers to the relative position of the renal corpuscle of this nephron – near the medulla, but still in the cortex.
Do reptiles have Juxtamedullary nephrons?
Lizards and other such organisms do not have complex juxtamedullary nephrons. Instead, these organisms have cortical nephrons with a shorter loop of Henle.
Which animal has the best kidney?
Some mammals have more efficient kidneys than ours. The kangaroo rat of the desert can produce a urine 17 times more concentrated that its blood. (The best we can do is 3-4 times as concentrated.)
Which of the following animals has the longest nephron loop?
The kangaroo rat’s kidneys are well-organized and produce only small quantities of urine, which is highly concentrated. They are said to have very long loops of Henle. These long loops of Henle allows the water to be reabsorbed efficiently.
How are camels adapted to the desert?
Camels are well adapted for survival in the desert. Their adaptations include: large, flat feet – to spread their weight on the sand. thick fur on the top of the body for shade, and thin fur elsewhere to allow easy heat loss.
How are desert animals excretory systems adapted?
Desert mammals do not readily find water, hence they must excrete very less amount of water. They are able to produce highly concentrated urine. The Henle’s loops of juxtamedullary nephrons along with counter flowing blood vessels, called vasa recta, help in conservation of water.
Which one is a characteristic of nephron of desert mammal?
What is the number of nephrons in a camel’s kidney?
The nephrons in desert mammal Camel are equipped with well developed Henle’s loop and number of juxtamedullary nephrons in kidneys is very high, about 35\% (in man this number is about 15\%).
What is an adaptive feature of nephron in a desert mammal?
What is an adaptive feature of nephron in a desert mammal, like camel? The nephrons in desert mammal Camel are equipped with well developed Henle’s loop and number of juxtamedullary nephrons in kidneys is very high, about 35\% (in man this number is about 15\%).
What is the difference between a general and a mammalian nephron?
The picture below is of a general nephron. This nephron contains a loop of Henle, so it is a mammalian nephron. While the loop of the nephron is special to mammals, the rest of the structure is seen in all vertebrate animals.
Why do the kidneys of desert animals have longer loops of Henle?
Kidneys of desert animals have longer loops of Henle to make the animals’ urine as concentrated as possible and limit the amount of water and salt they loose. This helps desert animals live for long periods of time on minimal amounts of water. The loops of Henle are found in the kidneys of reptiles,…
