Purpose The digestive system prepares food for use by hundreds of millions of body cells. Food when eaten cannot reach cells (because it cannot pass through the intestinal walls to the bloodstream and‚ if it could would not be in a useful chemical state. The gut modifies food physically and chemically and disposes of unusable waste. Physical and chemical modification (digestion) depends on exocrine and endocrine secretions and controlled movement of food through the digestive tract. Mouth Mouth

1. Within the circulatory system the liver has a unique anatomic location in that it effectively filters all blood coming from the intestinal tract by way of the portal vein before it is pumped to the general circulation. The liver often sees drugs at their highest concentrations‚ since it is the first organ perfused by blood containing the drug after absorption from the intestinal tract. Approximately 10-15% of total blood volume can be presented to the liver at any given time. The entire absorbed

Because there is no alternative treatment to liver transplantation for most patients with end-stage liver disease‚ it is important that the CNS understand that the 6-month rule could be lethal in some circumstances. Early detection and treatment can be life-saving. Clinicians

Won Choi1‚* In the present study‚ the key gluconeogenic enzyme G6P activity was assayed in liver of diabetic rats because the liver is the main organ responsible for maintaining homeostasis of blood glucose. The activity of G6P is enhanced during diabetes [31]. The dearrangement in carbohydrate metabolism results in impaired glucose homeostasis leading to hyperglycaemia. WSREt and WSLEt replenished liver glycogen stores and suppressed the hepatic gluconeogenesis by decreasing activity of G6P. This
