Whitepunk [10]

Answer:

The ability of body systems to increase their function, given the need to adapt, is known as the <u>physiologic reserve.</u>

Explanation:

The ability of body systems to increase their function if the need to adapt arises is known as a physiological reserve. Frequently, this term is used to refer to the operating limits of a particular physiological system when under stress. When this stress exceeds the ability of a particular organ or system to compensate for it, organ failure occurs. Adaptation achieves its highest efficiency when changes are generated gradually/progressively rather than abruptly. In aging, this reserve is diminished and therefore the ability of the organs to adapt to stress is lower, that is, the ability to adapt is reduced in extreme ages.
