Chemistry for Physiology

Glucose will dissolve in water, but being a molecular compound, it does not produce ions.

“Hypo-” means less concentrated than the solution inside a RBC. This in turn means that the concentration of water molecules is greater outside the cell than inside. So there will be a net water flow by osmosis into the RBC.

Acetylsalicylic acid is the medicine known as aspirin.

Extracellular must include the blood (vascular) and the fluid between cells (interstitial).

This states an amount of substance only, without reference to the volume of solvent involved.

Water will flow by osmosis from the RBC into the surrounding solution. If the difference in concentration is large enough, the outflow of water will be large, and the RBC will also shrivel (crenate) as a result of this outflow.

Although “pressure” appears in this term, it refers to the solution concentration when expressed in units of pressure. Choice D also refers to a concentration but of only one of the dissolved species.

0.1 mol = 1/10 of 58.5 g = 5.85 g

There is more K within cells than outside cells (the reverse is true for sodium). Most body water is inside the cells.

Outside the cells and inside the cells include everything.
