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 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 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.
Are Renal circulation and portal circulation different and why?
Yes, renal circulation refers to the blood flow through the kidneys, where blood is filtered and waste products are removed. Portal circulation refers to the blood flow from the gastrointestinal tract to the liver before returning to the heart. These circulations are different due to their distinct anatomical pathways and unique functions in the body.
What system in the body filters blood?
The system in the body that filters blood is the renal system, specifically the kidneys.
After filtering by the nephron where does the cleaned blood go?
Into the ureter.
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 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 is left renal agenesis?
I would assume it mean absent of the left renal function or kidney
What is the function of the renal portal system?
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.
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 name of artery present in rabbit but absent in frog?
portal artery or phrenic artery or sciatic artery or renal artery
What is the cure for portal hypertension?
distal splenal renal shunt
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 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 splenorenal shunting?
The splenic vein (a part of the portal vein), is connected to the renal vein.
What are the 4 blood circulation?
it is 5. the pulmonary,systemic,renal,portal, coronary circulation
