The digestive and urinary systems are the body's behavior and treatment plant residues and its mechanism. The digestive system (also called the bowel) begins in the mouth and ends at the anus. At the top, food come into the mouth where it is chewed and combined with saliva, which has enzymes to begin the breakdown of food into useful components. He goes into the digestive tract, where it juices breaks the food into proteins, fats and carbohydrates and get ahead of and pass it to the stomach.
Diet and Nutrition Research shows that eating more fiber in the form of oats, dried beans, peas, fruits and vegetables can greatly reduce the symptoms of Irritable Bowel Syndrome, but improvement may take months, not weeks. Also, keep in mind that wheat bran, often prescribed as the standard treatment for IBS, can actually make the condition worse for some patients. Eat plenty of natural resources, live unsweetened yogurt or taking daily supplements of Lactobacillus acidophilus to increase levels of healthy bacteria in the digestive system.
Some substances (water, salts, glucose, alcohol and some drugs) are absorbed directly into the system from the stomach. Most foods, however, is transformed by gastric juices of the stomach acid into a substance called chyme. Chyme passes from the stomach through the duodenum into the small intestine, where it is bathed in bile from the gallbladder and pancreatic juices. Powerful muscular contractions (peristalsis) to push the chyme along the small intestine, and to the extent that revenue more digestive juices and enzymes break it down into fats, carbohydrates and proteins. These are absorbed into the bloodstream through the walls of the small intestine. A pass from the blood to the liver, which is very important in the digestive process, the storage of sugar, fats and proteins, and creates bile. The liver is also responsible for neutralizing toxins such as alcohol and drugs.
By the time the chyme reaches the colon (large intestine), all that is left is indigestible roughage and water. The water is absorbed into the blood back through the intestinal walls. The main function of the great and large intestine is to recover the water supply. The bulky remains are passed as feces in the rectum and from here are expelled as a bowel movement.
The function of the urinary system, which consists of the kidneys and bladder, together with its connecting tubes, is to keep the internal balance of body water and salts. It is also responsible for filtering the blood and expels excess and waste products. The kidneys also beach vital role in the elimination of toxins and secrete important hormones. The kidneys are made up of enthrones, which are responsible for filtering the smallest molecules from the blood, including water, glucose, and waste products. The kidneys have a striking blood supply - more than 300pt/150l blood passes through them every day to form the 2pt/1l of urine the body produces daily. Urine is formed in the kidneys down the urethras and is stored in the bladder until it is convenient to empty it. The bladder drainage through the urethra. In females, the urethra is about 1 1/2in/4cm long, but it 10in/25cm long in males. The bladder is a fibrous organ that expands and extends from filling with urine. When it reaches its capacity it sends a message to the brain, which recognizes that water should be approved.
