5. A hungry person had a meal, after which the concentration of glucose and amino acids in the blood were determined. This was measured hourly as the blood passed through the hepatic portal vein and the iliac vein in the leg. The results were as shown in the table below. Time (Hrs) Concentration of contents in Concentration of contents in the Hepatic portal vein (Mg/100ml) iliac vein of the leg (Mg/100ml) Glucose Amino acids Glucose Amino acids 85 1.0 85 1.0 1 85 1.0 85 1.0 2 140 1.0 125 1.0 3 130 1.5 110 1.5 4 110 1.5 90 3.0 5 90 3.0 90 2.0 6 90 2.0 90 1.0 7. 90 1.0 90 1.0 a) Using the same axes draw graphs of concentration of glucose in the hepatic portal vein and the iliac vein in the leg against time (7mks) b) Account for the concentration of glucose in the hepatic portal vein from; i) 0-1 hour (2mks) ii) 1-2 hours (3mks) ​
