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 fluid compartment called the blood volume is interesting in that it is a composite compartment containing ECF (plasma) and ICF (red cell water). The fluid of bone & dense connective tissue is significant because it contains about 15% of the total body water.eonates contain more water then adults: 75-80% water with proportionately more extracellular fluid (ECF) then adults. At birth, the amount of interstitial fluid is proportionally three times larger than in an adult.
