What organ contains lobules with sinusoids that lead to a central venous structure?
The liver contains lobules with sinusoids that lead to a central vein called the central vein or hepatic vein. Each lobule is made up of hepatic cells (hepatocytes) arranged around a central vein, which functions to drain blood from the sinusoids in the lobule.
Explain what is portal circulation?
portal circulation refers to the circulation of the blood from the small intestine to the liver, via the portal vein. Blood flow to the liver is unique in that it receives oxygenated and de-oxygenated blood. Blood passes from branches of the portal vein through cavities between "plates" of hepetocytes called sinusoids. Blood also flows from branches of the hepatic artery and mixes into the sinusoids to supply the hepatocytes with oxygen. This mixture percolates through the sinusoids and collects in a central vein which drain into the hepatic vein. The hepatic vein subsequently drains into the inferior vena cava. =)
How many mosquitoes would it take to completely drain a human of blood?
It would take about 1.2 million mosquitoes to completely drain a human of blood.
What is found within the dural sinuses of the brain?
The dural sinuses are blood-filled channels located between the layers of the dura mater, the outermost membrane surrounding the brain. They collect blood from the brain and drain it back into the systemic circulation through the internal jugular vein. The sinuses contain venous blood, cerebrospinal fluid, and arachnoid granulations.
What is a vampire stem?
A vampire stem cell is a type of stem cell that has the potential to develop into white blood cells within the immune system. These cells can help replenish and repair damaged blood cells in conditions like leukemia and other blood disorders.

Which vessel contains blood with the highest amino acid content after a meal?
The answer is the hepatic portal vein,Unlike most veins, the hepatic portal vein does not drain into the heart. Rather, it is part of a portal venous system that delivers venous blood into another capillary system, namely the hepatic sinusoids of the liver. The hepatic portal vein (often simply portal vein) is a vein in the abdominal cavity that drains blood from the gastrointestinal tract
What veins drain the liver?
hepatic
What is the function of the hepatic veins?
In human anatomy, the hepatic veins are the veinsthat drain de-oxygenated blood from the liverinto the inferior vena cava.

What is the difference in function between the hepatic artery and the hepatic portal vein?
The hepatic portal vein transports blood high on glucose concentration and amino acids from the small intestine to the liver while the Hepatic vein transports deoxygenated blood from the liver to the heart and remaining glucose and amino acids to the rest of the body.
Which vessels drain into the hepatic portal vein?
inferior mesentaric and splenic
Veins that lead to the liver?
there are two types of vessels in our body to circulate blood . they are1 arteries - collect the deoxygenated, impure blood from all parts o of the body to theheart (except pulmonary artery which carry oxygenated pure bblood from the lungs to the heart)2veins-- carry pure and oxygenated blood from the heart to various parts of the body(except pulmonary vein which carry the impure deoxygenated impure blood from the heart to the lungs)hencehepatic veins are the veins which carries the impure ,deoxygenated blood, collecting from the liver by the hepatic venules to the heart to purify the blood with oxygen.
What is the main purpose of the hepatic-portal circulation?
Hepatic Portal Circulation The veins of the hepatic portal circulation drain the digestive organs, spleen, and pancreas and deliver the blood to the liver via hepatic portal vein. As blood percolates through the liver, some of the nutrients are stored or processed in various ways for release to the general circulation. The liver in turn is drained by the hepatic veins that enter the inferior vena cava. The inferior mesenteric vein, draining the distal part of the large intestine, joins the splenic vein, which drains the spleen, pancreas and stomach. The splenic vein and the superior meseteric vein, which drains the small intestine and the proximal colon, unite to form the hepatic portal vein. The left gastric vein, which drains the lesser curvature of the stomach, drains directly into the hepatic portal vein.

What is the blood supply to the lungs?
Blood leaving the liver can reach the lungs only via the right heart. It travels for the liver through the hepatic [liver] vein to the vena cava [the main vein carrying blood leaving the body], into the right heart [first the right atrium, then the right ventricle], and then through the pulmonary [lung] artery to the lungs .
What is the path that blood follows through the body beginning at the heart?
The path of blood from the heart to the kidneys is first from the abdominal aorta the blood enters the kidney through the renal artery. Then the renal artery divides into a number of segmental arteries. The segments arteries divide into lobar artery. The lobar arteries divide into inter-lobar arteries that travel between the renal pyramids. The inter-lobar arteries branch into arcuate arteries that travel between the cortex and medulla. From the arcuate arteries the blood is carried into the nephrons. In the nephron the blood enters through the afferent arteriole and into the glomerulus. The blood leaves the glomerulus by the way of the efferent arteriole, which the blood is carried to the peritubular capillaries, and finally to the vasa recta. When the blood reached the vasa recta that means that it had travelled through the whole nephron. The blood travels back to the heart through the veins. First through the interlobular vain, then through the arcuate vein, then through the interlobar vain, then through the segmental vain, and finally exists the kidney by the way of renal vein, and into the inferior vena cava.
How do oxygen and particles of digested food get into the cells of your body?
Oxygen and particles of digested food get into the cells from the small intestine, from there they drain into the hepatic portal vein. The hepatic portal vein goes to the liver to filter out nutrients required and excesses are metabolized and converted.
