Fluid Electrolyte & Acid-Base Balance

Fluid located within the cell.

Comprises all the fluid outside the cell

ECF include this fluid the fluid inside the blood and lymphatic vessels.

The fluid between the cells.

Stretch receptors, known as pressure receptors that are located in major arteries and veins that monitor vascular volume.

The proportion of dissolved particles (solute) in a volume of fluid.

The concentration of dissolved substances in given weight of fluid rather than in a given volume.

Chemical compounds that partially dissociate (separate) in solution into separate particles.

Separated particlas that carry electrical charges.

Positively charged ions

Negatively charged ions.

Electrolyte concentrations are expressed in terms of their combining power, or the ability of cations to combine with anions, rather than by their absolute weight in solution. The measure of chemical activity.

The movement of a solvent or solutes (molecules) from an area of higher solvent or solute concentration to an area of lower solvent or solute concentration.

The movement of a fluid through a semipermeable membrane.

Osmosis can occur if a semipermeable membrane separating two fluid compartments is permeable to water and if one compartment contains concentration of a dissolved substance.

Osmosis can occur if a semipermeable membrane separating two fluid compartments is permeable to water and if one compartment contains less than the other compartment

The process by which ions and other molecules are moved across membranes from an area of lesser concentration to an area of greater concentration.

Involves the transfer of water and dissolved substances through a permeable membrane from a region of high pressure to a region of low pressure.

The force of attraction for water by undissolved particles, helps to keep fluid within blood vessels, opposing net flow outward.

Refers to a fluid's effect on cell size.

Solution that has a concentraiton of solute that is less than that of blood plasma.

Solution that has a concetration of a solute is greater than that of a blood plasma.

Any substance that can donate free H+ ions to a solutions.

Any substance that can decrease [H+] in a solution.

Substances that help to prevent large changes in pH by absorbing or releasing H+ ions.
