Question

Which blood vessel-mesenteric artery, hepatie portal vein, or hepatic vein-contains more glucose after eating? do you suppose the hepatic vein does not contain as much glucose as the hepatic portal vein after eating To complete your study, rear the glucose concentration of three samples an animal that had not eaten for some time. Label and mark three test tubes at 2 cm and 4 cm, and fill to mark with experimental serum A,, B,, or Ca and to the 4 cm mark with Benedict's reagen water bath at the same time; whichever contains the most glucose turns color first. Record your results in of serum taken from the same locations in t. Heat the samples in a boiling table 14.2 by listing the order in which the tubes showed a color change Table 142 Glucose concentrations before eating Which blood vessel-mesenteric artery, hepatic portal vein, or hepatic vein- contains the most glucose before eating? Why do you suppose the hepatic vein now contains more glucose than the bepatic portal vein? Storage of Glucose as Glycogen Just after eating, the liver stores excess glucose as glycogen. In between eating glycogen is broken down by liver cells to produce glucose and this glucose enters the bloodstream to maintain the blood sugar level at 0.1%. In the equation that follows, write the phrases after eating and before eating on the appropriate line. n glucose glycogen The hormone insulin, made by the pancreas, promotes the uptake and storage of glucose in the liver. Add the wo insulin to the appropriate arrow in the equation. If the pancreas ceases to make insulin, glucose is excreted in the ur nstead of being stored. The individual then has the medical condition called diabetes mellitis. State here one way in which the liver contributes to homeostasis. 6

Explanation / Answer

Hepatic vein contains the most glucose before eating and hepatic portail vein contains the most glucose aftee eating as the liver removes sugar from blood and convert it into glycogen. After a meal, the digested nutrients are carried by venous circulation and poured into hepatic portal vein.

Liver contributes to hemostasis by maintaining blood glucose level. When the blood glucose level is too high, it lowers it down by converting into glycogen and vice versa. The liver responds to insulin and glucagon to keep the level of glucose maintained in the blood. It also maintains the temperature of the body through various metabolic processes.
