reserve, alkaline,
n (alkali reserve), 1. the amount of buffer compounds (e.g., sodium bicarbonate, dipotassium phosphate, proteins) in the blood capable of neutralizing acids; one of the buffer systems of the blood that can neutralize the acid valences formed in the body. It is made up of the base of weak acid salts and is usually measured by determining the bicarbonate concentration of the plasma.
n 2. the concentration of bicarbonate ions (HCO3) in the blood. These ions serve as a reserve in that they may be displaced by anions (e.g., Cl, SO4−2, PO4−3). Displacement of bicarbonate ions occurs mainly by means of the chloride shift. The role of the buffer system is such that a large influx of acid or base ions from either metabolic function or ingestion can be neutralized by the alkaline reserves from the mineral and protein salts in the blood and tissue fluids. A strong acid is transformed into a weak base. Consequently, the pH level of the blood fluctuates very little, and the tissue cells are constantly bathed in a continuously buffered solution.
reserve, cardiac,
n the reserve strength or pumping ability of the heart, which may be called on in an emergency.
