Insulin is the biological chemical that works as an effect to lower blood glucose levels in the blood. It consists of two amino acid chain linked together by disulfide bonds. It is released by beta cells of the pancreatic cells. The beta cell releases this protein when it senses a rise in our blood sugar level or after we have just eaten. After being made by the beta cells in the pancreas, insulin travels down to the body 's tissue cells to be taken up by the body 's cell. Insulin also stimulates glycogen formation in the liver. In the liver, glucose is converted to glycogen which can then be stored in the body for later uses. The uptake of the sugar by the body’s cells reduces the blood glucose sugar in the body, bringing back …show more content…
Glucagon on the other does the opposite of insulin by acting to bring up blood glucose level when it is low. Glucagon is created by alpha cells in the pancreas. It is activated when there is a decrease in the blood glucose level during the fasting phase of metabolism. After being released from the pancreas by the alpha cell, glycogen travels to the liver to break apart the glycogen to glucose. This uprise in glucose molecule will eventually bring up your blood glucose level to its normal range. This two biological mechanism, insulin, and glycogen, both work together to maintain blood glucose and to make sure the body its getting efficient glucose to the body. The mesenteric artery takes nutrient from the heart to the intestines, while the hepatic portal vein takes nutrients from the intestines to the liver. Lastly, the hepatic vein drains the nutrients from the liver to the inferior cava and eventually to the heart. The mechanism that controls how insulin and glucagon are distributed is hormonal. The focus of this experiment is to be to see stimulate and examine the amount of glucose in the mesenteric arteries, hepatic vein, and hepatic portal vein before and after eating. This is done with an aim to map out the effects of glucagon and …show more content…
It was hypothesized that glucose would be taken up first in the mesenteric to the hepatic portal and then the hepatic vein in the fed phase and the reverse in the fasting phase.In the data above it shows that mesenteric artery had the largest amount of glucose followed by hepatic vein and then the hepatic portal vein being the least in the fed phase. In the fasting phase, the hepatic portal vein had the largest amount of glucose followed by the mesenteric artery and finally the hepatic vein. Possible sources of error to have occurred in this lap was the variability of the color changes between the vessels because color has a ray of different shades it 's hard to pinpoint what shade of color the vessels represent. Also, the amount of Benedict that was put in each serum also play an influence, because each drop wasn 't measured to be the same, the amount of Benedict could have disrupted the data collected. For people with hypoglycemia in the hospital setting, blood glucose is evaluated by blood glucose test are administered to the patients to check their blood glucose level. Testing the blood glucose determined either or not the patients should be treated for hyperglycemia (high blood glucose) or hypoglycemia (low blood glucose). Blood glucose can also be determined by laboratory instrument and point of care bedside glucose meter for the convenience of the
