Tes Global Ltd is [citation needed] It is characterized by decreases in mean arterial pressure and stroke volume and a parallel increase in heart rate. The human cardiovascular system is responsible for delivering a continuous supply of oxygen and nutrients to active muscles, which maintains a high level of energy transfer, while also removing metabolites. As a result, our heart rate must increase to compensate for the reduction in stroke volume, leading to aphenomenon known as cardiovascular drift. I have found over many years of teaching PE and sport courses for GCSE, A-level, BTEC, VCERT, Cambridge National and Cambridge Technical that students need significant guidance on forming good quality practical examples (normally for AO2).The aim of this post is to set a standard for how practical examples should be structured to give the maximum opportunity to achieve marks in examined or .
