The polyol pathway is a two-step process that converts glucose to fructose. [1] In this pathway glucose is reduced to sorbitol, which is subsequently oxidized to fructose. It is also called the sorbitol-aldose reductase pathway. The pathway is implicated in diabetic complications, especially in microvascular damage to the retina, [2] kidney, [3 ...
Liver and gall bladder. The liver is the second largest organ (after the skin) and is an accessory digestive gland which plays a role in the body's metabolism. The liver has many functions some of which are important to digestion. The liver can detoxify various metabolites; synthesise proteins and produce biochemicals needed for digestion.
The gallbladder is located on the undersurface of the right lobe of the liver. [9] It produces bile, which is used to help process fats in the body. [9] Humans can live without the gallbladder. [10] The largest lymphatic organ is the spleen, which is dark purple and located under the lower ribs, around the left side of the upper abdomen.
The function of the common bile duct is to allow bile to travel from the gallbladder to the small intestine, mixing with pancreatic digestive enzymes along the way. [4] One possible complication of choledocholithiasis is an infection of the bile ducts between the liver and the gallstone lodged in the common bile duct.
The kidneys are large, bean-shaped organs which are present on each side of the vertebral column in the abdominal cavity. Humans have two kidneys that are supplied with blood from the renal artery. The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine.
Other organs, such as the kidneys, also have roles within the endocrine system by secreting certain hormones. The study of the endocrine system and its disorders is known as endocrinology . The thyroid secretes thyroxine , the pituitary secretes growth hormone , the pineal secretes melatonin , the testis secretes testosterone , and the ovaries ...
The free glucose molecules can be transported out of the liver cells into the blood to maintain an adequate supply of glucose to the brain and other organs. Glycogenolysis can supply the glucose needs of an adult body for 12–18 hours.
D-xylose absorption test is a medical test performed to diagnose conditions that present with malabsorption of the proximal small intestine [1] due to defects in the integrity of the gastrointestinal mucosa. [2]
