The purpose of this experiment was for the researcher to study one of the process of digestion which is absorption, and seeing if starch and glucose could diffuse through the dialysis tubing, and could the two be absorbed by the small intestines, and if so or not, why? To begin, in this experiment, the researchers gathered different solutions, such as, starch and glucose, filling half of each mixtures in a single dialysis tube. The researchers carefully then rinsed and pat dry the dialysis tube, to insure that the nutrients were removed. By placing the tube in a 250-mL beaker, submerged in 50-mL of distilled water. Insuring that the dialysis is completely submerged. The researcher …show more content…
As, we know that absorption is the uptake of fluids or other substances by the tissues of the body. Most of the absorption of the digestive process occurs in the jejunum and the ileum of the small intestine. The small intestine is lined with finger-like projections called villi. Villi greatly increase its surface area, and therefore the rate at which absorption can take place. Small intestine delivers chyme to the large intestine. Chyme is food in the stomach that is partly digested and mixed with stomach acids. We know that the small intestine is composed of three layers that is the mucosa, submucosa, muscularis externa, and serosa. Mucosa layer consisting of the lamina propria and stratified squamous or columnar epithelium. Submucosa layer consisting of layer that contains GALT (gut-associated lymphoid tissue). Muscularis externa consisting layers of circular and longitudinal muscle layers. Serosa the layer that consists of the visceral and parietal peritoneum. The small intestine also can absorb simple sugars, amino acids, fats. Now knowing about the small intestine and absorption. The researchers then tested an experiment on absorption in the small intestine using a dialysis tube and seeing if starch and glucose could diffuse and if so, could it be absorbed by the small intestine. Well dialysis tube is also known as visking tubing, is a type of semi-permeable membrane tubing used in separation techniques that facilitates the removal or exchange of small molecules from macromolecules in solution based on differential diffusion. It basically mimics a cell’s permeability only allowing small particles to diffuse and not for large particles. So the researchers identified that glucose which defines as a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates. Glucose is permeable can pass through the microscopic
