Table of contentsDiscussionConclusionReferencesDiscussionThis experiment involves analyzing renal filtration using a simple filtration system. In this experiment, protein, glucose and starch were used as test substances. The procedure is repeated because the first experiment was as a standard solution for the second experiment.

It was used as a standard solution for test tube and test tube. Among the substances tested, some of the compound passed through the filter paper, others did not. Protein and glucose can pass through the filter paper, but starch cannot pass through the filter paper. Starch was a large molecule compound, so it could not pass through the filter paper which was semi-permeable. Protein and glucose could pass through the filter paper because they were smaller than starch. The results were observed and recorded after the experiment. The color intensity before filtration and after filtration is different. The colors were different because the filtrate was higher or lower than the substances tested before filtration. The color observed is similar for the substances before filtration and after filtration, it was difficult to judge the color. The color should use a color chart to judge more accurately. The filtration experience was like kidney function. The substances tested were molecules present in the kidney which had to be filtered. The filter paper was semi-permeable and resembled a kidney membrane that was also semi-permeable. The color intensity of the test tube before and after filtration corresponded to the substances or molecules present in the kidney necessary for filtration. The nephron is the basic functional unit of the kidney. Each nephron consisted of Bowman's capsule, glomerulus, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct. The glomerulus was a network of capillaries surrounded by Bowman's capsule. The afferent arteriole supplied blood to the glomerulus, the efferent arterioles carried blood from the glomerulus to the second capillary network surrounding the proximal convoluted tubule. The proximal convoluted tubule reabsorbs ions, water and nutrients. The Loop of Henle has a descending limb and an ascending limb. The descending limb of the Henle loop is only permeable to water, water will be diffused by osmosis but sodium ions, potassium ions and chlorine ions will not be actively pumped out. The ascending branch of Henle's loop, permeable only to salt, sodium ions, potassium ions and chlorine ions were actively pumped, but water did not diffuse by osmosis. Water, sodium ions, potassium ions, and chlorine ions were diffused into the vasa recta and carried away. The distal convoluted tubule reabsorbed NaCl and HCO3-, potassium ions and hydrogen ions were actively pumped out. The collecting duct reabsorbed water by osmosis and the amount of water was regulated by antidiuretic hormone (ADH). Mammals had to get rid of excretory products, because if the allowed waste products remained in the cells, they could be toxic or poisonous to the cells. Keep in mind: this is just a sample.
