Registered office: International House, Queens Road, Brighton, BN1 3XE. From a body composition perspective, water is important in the metabolism of fats, as fats are only utilised in the muscle cells and for muscle cells to work they require water. Furthermore, when core body temperature increases the body responds by increasing skin blood flow to help control the temperature rise. 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. Analysis of Movement. Septum. The smaller chamber of the heart, which has thinner muscular walls. What increases during cardiovascular drift? Cardiac output is the product of stroke volume and heart rate. The bodysAutonomic Nervous System (ANS) is responsible for regulating physiological processes such as breathing and blood pressure.
