Dynamic reserve
Dynamic Reserve
Dynamic reserve (pronunciation: /daɪˈnamɪk rɪˈzɜːrv/) is a term used in medicine and physiology to describe the body's ability to adapt to changing physiological demands. The concept is often applied in the context of cardiovascular and respiratory systems, but it can also refer to other systems in the body.
Etymology
The term "dynamic reserve" is derived from the Greek word "dynamis" meaning power, and the Latin word "reservare" meaning to keep back or save for future use. It was first used in medical literature in the late 20th century.
Definition
