The wastes and surplus ions in the venous blood from caudal region of fish are respectively eliminated and absorbed in the kidney tubules. This lowers the osmotic pressure of the extracellular fluid that in turn reduces the osmotic intake of water into the body, thereby playing an important role in osmoregulation in Pisces.

Why is renal portal system absent in humans?
Humans have a hepatic portal system that brings all the venous flow from the digestive system into the liver. Reptiles have a renal portal system, which brings blood from internal organs to their kidneys, mostly because their digestive tract and urinary tract only have the cloaca to eliminate waste from their body. Since humans have separate systems for eliminating waste, the anus and urethra, the human body, like all other mammals, developed a hepatic portal system.
What are the effects of hypokalemia in renal system?
Hypokalemia in the renal system can lead to impaired kidney function, electrolyte imbalances, and increased risk of kidney stone formation. It can also cause metabolic alkalosis due to increased renal bicarbonate reabsorption. Additionally, hypokalemia can affect the renal tubules' ability to concentrate urine properly.
What makes up the renal portal system?
It is made up of the afferent arteriole which supplies blood to the kidneys. The glomerulus, which is the first capillary bed produces filtrate. The efferent arteriole takes blood from the kidneys. The peritubular capillary system, which is the second capillary bed reclaims most of the filtrate. Filtrate is what eventually becomes urine.
What is renal reserve?
Renal reserve refers to the ability of the kidneys to increase their level of function above baseline in order to compensate for renal damage or loss of kidney function. It essentially represents the kidney's ability to adapt and maintain normal renal function under various conditions.
What are the 5 functions of the renal system?
The main function of the renal system is to get rid of waste that is found in the urine. The amino acids that are not immediately required are broken down in the liver to make urea, this urea is carried in the bloodstream to the kidneys for elimination of waste.Read more: What_are_the_functions_of_the_renal_system

What is a portal circuit and a renal circuit?
A portal circuit is found in the cardiovascular system. A renal circuit is found in the kidneys. Both are fond in the arteries in either organ
What is unusual about the hepatic portal vein?
The hepatic portal vein in frogs is unusual in that it is divided into two portals, the hepatic and the renal. In higher vertebrates, the hepatic portal system is the only one present.

What isa the function renal pelvis in excretory system?
The renal pelvis collects urine filtrate from the collecting tubules.
What are the PORTAL systems in the human body?
Portals systems in the human body refer to blood vessels that allow for the transport of blood between two different organ systems before returning to the heart. The hepatic portal system, for example, carries nutrient-rich blood from the digestive system to the liver for processing.
What is the cure for portal hypertension?
distal splenal renal shunt
What is the function of the renal vein?
The main function of a renal vein is to carry blood from the kidneys
What is the medical term that refers to kidney function?
Renal function is the medical term meaning kidney function. Renal means pertaining to the kidney.
What does the renal system refer to?
The renal system refers to the organs responsible for filtering waste products from the blood and regulating fluid balance in the body. This includes the kidneys, ureters, bladder, and urethra. The main function of the renal system is to maintain homeostasis by filtering blood, removing waste, and producing urine.
What is the difference between renal and hepatic circulation?
Renal circulation, receiving about 20% of cardiac output, branches from the abdominal aorta and returns to the ascending vena cava. Hepatic circulation is the system of veins made of the hepatic portal vein and its tributaries.
What are the effects of hypokalemia in renal system?
Hypokalemia in the renal system can lead to impaired kidney function, electrolyte imbalances, and increased risk of kidney stone formation. It can also cause metabolic alkalosis due to increased renal bicarbonate reabsorption. Additionally, hypokalemia can affect the renal tubules' ability to concentrate urine properly.
