- the presence of bacteria in the bloodstream.
- biological system that enables individuals to know where their bodies are in the environment and to maintain a desired position; normal balance depends on information from the labyrinth in the inner ear, and from other senses such as sight and touch, as well as from muscle movement.
- balance disorder
- disruption in the labyrinth, the inner ear organ that controls the balance system allowing individuals to know where their bodies are in the environment.
- balloon urethroplasty

- a metallic chemical (chalky liquid) used to coat the inside of the organs so that they will show up on an x-ray.
- barium beefsteak meal
- during this test, the patient eats a meal containing barium, allowing the radiologist to watch the stomach as it digests the meal. The amount of time it takes for the barium meal to be digested and leave the stomach gives the physician an idea of how well the stomach is working and helps to detect emptying problems that may not show up on the liquid barium x-ray.
- barium enema (Also called lower GI, or gastrointestinal, series.)
- a procedure that examines the rectum, the large intestine, and the lower part of the small intestine. A fluid called barium (a metallic, chemical, chalky, liquid used to coat the inside of organs so that they will show up on an x-ray) is given into the rectum as an enema. An x-ray of the abdomen shows strictures (narrowed areas), obstructions (blockages), and other problems.
- barium enema x-ray
lower gastrointestinal (GI) series.
- barium swallow
upper gastrointestinal (GI) series.
- barium x-rays
- a type of diagnostic x-ray in which barium is used to diagnose abnormalities of the digestive tract. Barium enema, barium small-bowel enema, and barium swallow are types of barium x-rays.

- basal ganglia
- several large clusters of nerve cells, including the striatum and the substantia nigra, deep in the brain below the cerebral hemispheres.
- basal metabolic rate (BMR)
- a measurement of energy required to keep the body functioning at rest. Measured in calories, metabolic rates increase with exertion, stress, fear, and illness.
