Before we take a dive into the deep end, lets get started byfirstdefining the key terms related to cardiac drift. Abstract. Respiration increases during exercise to meet the oxygen demand of the working muscles, resulting in a rise in water vapour loss through breathing, whilst sweat is lost in order to maintain body temperature. The process of gradual adaption to a change in environment is known as A hormone produced and released by the kidney that stimulates the production of red blood cells by the bone marrow.
