Document Summary
Ability to conform to shape of whatever container holds them. Extracellular fluid: fluid outside the body"s cells tissue fluid (flows between cells that make up tissues and organs) plasma (liquid portion of blood and vessels) Body fluid composition varies: tissue type, lean tissue: 70% fluid, fat: 10-20, males have more lean tissue and more body weight fluid, decreases w/ age due to loss of lean tissue and fluid, gender, age. Solutes: dissolved substances within body fluid: four major minerals/ electrolytes: Sodium, potassium, chloride and phosphorus (all consumed in salt) Na and k = + / cl and hpo42 is . Intracellular fluid has: k and hpo42: leaves slight difference of charge on either side of the membrane. Electrolytes: substance that disassociates in solution and form into ions which carry an electrical current: ions: + or charged ions. Spark that stimulates nerves and causes muscles to contract = makes electrolytes critical to body function.
