Document Summary
Chapter 6- fluid regulation- water, electrolyte and ph imbalances. Acid-base imbalances: review of water homeostasis, body fluids are solutions composed of water, electrolytes, nonelectrolytes electrolytes cations: na+, k+; anions: cl- Nonelectrolytes glucose, urea: body fluids are contained in two major compartments, extracellular fluid (ecf) and intracellular fluid, the composition of body fluids is maintained within narrow limits despite variations in dietary intake (icf). and cellular activities. Extracellular fluid (ecf) plasma: sodium ions (na+), potassium ions (k+), calcium ions (ca++), bicarbonate (hco3, chloride ions, phosphate, serum proteins: 156 meq/l: potassium ions, sodium, phosphate ions, sulphate ions, water, proteins: large quantity found in cell (e. g. hemoglobin, hormones, neurotransmitters, enzymes. ~10 meql etc all of which are proteins) Function of body fluids and electrolytes: water, solvent and transporter of nutrients, oxygen and wastes, protects organs: synovial and serous fluid, csf, body temperature regulation (evaporative heat loss, medium for chemical reactions.
