The world is facing an epidemic of cocaine use by adolescents and young adults from all socioeconomic backgrounds. Epidemiologic data suggest that cocaine use is a serious public health problem because it is highly addictive and is associated with a variety of neurological complications. Cocaine‚ a natural alkaloid‚ is extracted from leaves of an Andean shrub‚ Erythroxylon coca. Coca leaves were used by the native populations to alleviate the rigors of high altitude and to diminish

position was coined the Trendelenburg position which to this day still bears his name. Years later‚ during the First World War‚ the American physiologist Walter B. Cannon adopted this position to displace blood from the lower extremities to enhance venous return in the treatment of hemorrhagic hypovolemic shock. This action was thought to cause an “autotransfusion” to the central circulation‚ increasing right and left ventricular pre-loads‚ stroke volume‚ and cardiac output or cardiac index. Although

“The structures of body systems are determined by their functions”. Discuss this statement‚ focussing on the Circulatory System. You should include diagrams and relevant examples in your essay. In order to survive it is necessary for every cell in the body to exchange materials as not all cells are in contact with the external environment; we rely on the circulatory system to do this which is composed of the heart‚ blood vessels and blood. The heart consists of four chambers two atria and two ventricles

Chronic Training Adaptations Exercise or training regularly over an extended period of time (3 times per week for 6-8 weeks) leads to the development of long-term or chronic adaptations to training. Evidence of these adaptations can occur at various stages Once achieved‚ these adaptations are retrained unless training ceases. Upon cessation‚ the body will gradually revert to its pre-training condition (de-training). Unlike acute responses to exercises‚ chronic adaptations to training
