Tuba section in a British style brass band. Tubas are found in various pitches, most commonly in F, E â­ , C, or B â­ . The main tube of a B â­ tuba is approximately 18 feet (5.5 m) long, while that of a C tuba is 16 feet (4.9 m), of an E â­ tuba 13 feet (4.0 m), and of an F tuba 12 feet (3.7 m). The instrument has a conical bore, meaning the bore diameter increases as a function of the tubing length from the mouthpiece to the bell.
The total body water is divided into intracellular and extracellular fluids. Plasma is considered __.
The human body may be conceptually divided into two major fluid compartments: the intracellular compartment and the extracellular compartment. The intracellular compartment is the space within the organism's cells; it is separated from the extracellular compartment by cell membrane.he third extracellular compartment, the transcellular, consists of those spaces in the body where fluid does not normally collect in larger amounts, or where any significant fluid collection is physiologically nonfunctional.
