What is the relationship between the digestive system and the excretion system?
The digestive system and the excretory system are two body systems with seemingly unrelated functions: food distribution for energy and excretion of waste from the body. However, there are a large number of relation between the digestive system and the excretion system. Especially the liver plays a role concerning both systems because it receives blood from the intestines and filters post-derisive waste such as drugs and alcohol before it is cycled back into the body. It then releases the bile, the substance necessary for the filtering process, back to the intestines in exchange. This bile then becomes part of a stool that is excluded from the body during defecation.
The digestive system includes all organs and passages of the digestive tract, including the mouth, neck, esophagus, stomach, liver, gallbladder, pancreatic, smcel intestine and large intestine. These organs are responsible for transporting, breaking and extracting nutrients from food that the body can use for energy and for other metabOlical processes. At the lower end of the digestive tract, the large intestine performs another function: removal of undigested food waste and bile from the body. This is one example of overlapping the relationship between the digestive system and the excretion system. This means that even if this type of waste removal is considered to be the function of the digestive system, because the intestines are namely the digestive organ where nutrients are absorbed into the bloodstream and not strictly organization, such as kidneys, contribute to the excretion process.
The bodies included in the excretory system are those that operate to remove waste, even if it may not do so exclusively. The kidneys and the bladder are included because they remove metabolic by -products such as salt and water. The lungs are included because they secrete carbon dioxide in exchange for oxygen, with carbon dioxideand by -product of metabolism. Simply put, any metabolic process or process in which energy is taken from food when calories burns, resulting in waste by -products, requires a excretion function.
Most overlap the relationship between the digestive system and the excretory system occurs in the liver. The liver is located along the stomach in the abdominal cavity; It is associated with the digestive tract by a large container called the liver portal vein. After drugs, alcohol or other toxic substances have reached the large intestine, they are absorbed by the intestinal wall into the bloodstream and are transported to the liver through the liver portal veins and then filmed from the bloodstream. In addition, the liver produces the bile, the substance that is released into the small intestine to emulsify the diet fat so that it can be absorbed by the body. Bull, as well as bilirubin or dead red blood cells contained in the bile, which are a by -product of metabolism in the liver, are then excluded from the body by the stool.
