As blood flows through the kidneys, the kidneys filter waste products, chemicals, and unneeded water from the blood. Urine collects in the middle of each kidney, in an area called the renal pelvis.

The kidneys also make substances that help control blood pressure and regulate the formation of red blood cells.

Laboratory: A place for doing tests and research procedures, and for preparing chemicals and some medications. Also known as lab.

Liver: The largest solid organ in the body, situated in the upper part of the abdomen on the right side. The liver has a multitude of important and complex functions, including to manufacture proteins, including albumin (to help maintain the volume of blood) and blood clotting factors; to synthesize, store, and process fats, including fatty acids (used for energy) and cholesterol; to metabolize and store carbohydrates (used as the source for the sugar in blood); to form and secrete bile that contains bile acids to aid in the intestinal absorption of fats and the fat-soluble vitamins A, D, E, and K; to eliminate, by metabolizing or secreting, the potentially harmful biochemical products produced by the body, such as bilirubin, from the breakdown of old red blood cells and ammonia from the breakdown of proteins; and to detoxify, by metabolizing and/or secreting, drugs, alcohol, and environmental toxins.

Nose: The external midline projection from the face. The purpose of the nose is to warm, clean, and humidify the air that a person breathes. In addition, it helps a person to smell and taste. The nose is divided into two passageways by a partition called the septum. Opening to these passageways are the nostrils. Bony projections, called turbinates, protrude into each breathing passage; they help to increase the surface area of the inside of the nose. There are three turbinates on each side of the nose (the inferior, middle, and superior turbinates). The sinuses are four paired air-filled chambers that empty into the nasal cavity.

Opiate: A medication or an illegal drug that is derived from the opium poppy or that mimics the effect of an opiate (a synthetic opiate).

Pain may be contained to a discrete area, as in an injury, or it can be more diffuse, as in disorders like fibromyalgia.

The nose makes extra mucus whenever something that is in the nose, such as pollen or dust, needs to be removed. Mucus formation is also part of the histamine reaction to allergies and of the body's defenses during respiratory infections.

Stomach: The digestive organ that is located in the upper abdomen, under the ribs. The upper part of the stomach connects to the esophagus, and the lower part leads into the small intestine. When food enters the stomach, muscles in the stomach wall create a rippling motion (peristalsis) that mixes and mashes the food. At the same time, juices made by glands in the lining of the stomach help digest the food. After about 3 hours, the food becomes a liquid and moves into the small intestine, where digestion continues.

The average amount of urine excreted in 24 hours is between 5 to 8 cups or 40 and 60 ounces. Chemically, urine is mainly a watery solution of salt and substances called urea and uric acid. Normally, it contains about 960 parts water to 40 parts solid matter. Abnormally, it may contain sugar (in diabetes), albumin (a protein, as in some forms of kidney disease), bile pigments (as in jaundice), or abnormal quantities of one or another of its normal components.

Withdrawal symptoms: Abnormal physical or psychological features that follow the abrupt discontinuation of a drug that has the capability of producing physical dependence. In example, common opiates withdrawal symptoms include sweating, goosebumps, vomiting, anxiety, insomnia, and muscle pain.
