Process of Absorpion n Transportation

• The lacteal in the villi absorbs digested fat and transfers it into the lymphatic system and then to the blood circulatory system.
• The surface of the small intestine has many folds called villi to increase the surface area and absorption rate of the products of digestion.
• The wall of the villus is very thin, only one cell thick, to increase the rate of absorption.
• Assimilation is the process of distributing the end products of digestion for the use of the cells in our body.
• The end products of digestion include glucose, amino acids, and fatty acids and glycerol.
• The digestive system breaks down large and complex particles of food into small and simple molecules so that they can be absorbed into the villi.
• The blood circulatory system transports small and simple molecules to the cells of the body.
• Blood capillaries in the wall of the villus transport small-sized nutrients that can go through the wall of the small intestine to the cells.
• Undigested food that is larger cannot go through the small intestine wall.
• Reabsorption in the large intestine involves the absorption of water and minerals into the bloodstream.
• The lacteal in the villi absorbs vitamin A,D,E and K and transfers it into the lymphatic system and then to the blood circulatory system.

• Glucose is used to produce energy for cell respiration
• Excess glucose will be converted to glycogen and stored in the liver
• Amino acid is used to form new cells and replace damaged cells
• Excess amino acid will be converted to urea and it will be eliminated by sweat and urine
• Fatty acid and glycerol are used as heat insulators and to protect internal organs
