Urinary tract infection - children This article discusses urinary tract infections in children. The infection can affect different parts of the urinary tract, including the bladder (cystitis), kidneys (pyelonephritis), and urethra, the tube that empties urine from the bladder to the outside. Urinary tract infections (UTIs) can occur when bacteria get into the bladder or the kidneys.

Human Physiology/Print Version The digestive system is made up of the alimentary canal (also called the digestive tract) and the other abdominal organs that play a part in digestion, such as the liver and pancreas. The alimentary canal is the long tube of organs — including the esophagus, stomach, and intestines — that runs from the mouth to the anus. An adult's digestive tract is about 30 feet (about 9 meters) long. Digestion begins in the mouth, well before food reaches the stomach.

Digestive System Overview Organs of the digestive system are divided into two main groups: organs within the alimentary canal and accessory digestive organs. The alimentary canal, which is also called the gastrointestinal (GI) tract or gut, is the entire length of tube that winds through the body from the mouth to the anus.It digests, breaks down and absorbs food through its lining into the blood.Organs within the alimentary canal include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. It involves a series of steps, but the main idea is that enzymes are secreted into the alimentary canal (GI tract) by accessory digestive glands and the gall bladder that aid in the breakdown of food molecules.

Intussusception Intussusception is the most common cause of intestinal obstruction in children between ages three months and three years old. Intussusception occurs when a portion of the intestine folds like a telescope, with one segment slipping inside another segment. It can occur in the colon, the small bowel, or between the small bowel and colon. The result can be a blocked small bowel or colon.

Gastrointestinal tract The mouth, oesophagus, stomach, and intestines are part of the human alimentary canal. All bilaterians have a gastrointestinal tract, also called a gut or an alimentary canal. This is a tube that transfers food to the organs of digestion. In large bilaterians, the gastrointestinal tract generally also has an exit, the anus, by which the animal disposes of feces (solid wastes).

The Digestive System Also called the throat, the pharynx is the portion of the digestive tract that receives the food from your mouth. Branching off the pharynx is the esophagus, which carries food to the stomach, and the trachea or windpipe, which carries air to the lungs.he digestive tract (or gastrointestinal tract) is a long twisting tube that starts at the mouth and ends at the anus. It is made up of a series of muscles that coordinate the movement of food and other cells that produce enzymes and hormones to aid in the breakdown of food.
