Describe the physiology of the cardiovascular system in relation to energy. A.T.P is stored, chemical energy in the cell, without A.T.P we would die. To make A.T.P we need glucose oxygen. Carbon dioxide and heat are the waste products. The main function of the cardiovascular system in relation to energy is to transport the oxygen and glucose to the cells, and to transport the waste products such as carbon dioxide and urea (waste product from protein digestion) away from the cells and to the lungs or kidneys. Blood is a liquid connective tissue as it is made up of living cells (red and white). Oxygen is transported in red blood cells, attached to a protein called haemoglobin while nutrients, including glucose, are dissolved in the†¦show more content†¦For this reason the muscular wall of the left side is thicker than that of the right side. The atria and ventricles are separated by valves known as the AV valves. The purpose of these valves is to prevent blood from flowing in the wrong direction. Following the movement of blood from the atrium, into the ventricle, the AV valve snaps shut which causes the first heart sound of the heart beat. The beat is caused by the closing of two other valves. Meaning The Sa node and Av node work together, forcing blood into the ventricles, which contract, forcing the blood to leave from the left side of the heart. The blood that enters the right side of the heart enters through veins as it is under less pressure. Blood with co2 in it will exit the right side of the heart through the pulmonary artery to the lungs where gaseous exchange occurs. Arteries and veins run parallel throughout the body, with a web-like network of capillaries, embedded in tissue, connecting them. Arteries: The arteries carry the blood away from the heart they have thick walls due to high blood pressure and the walls begin to get narrower as they have left the heart, this also increases pressure of the blood. This means the blood carrying the oxygen and glucose will flow around the body quickly and efficiently. The walls of the arteries are made of smooth muscle and lines with thin, smooth epithelial tissueShow MoreRelatedAssignment Brief to Break Down Unit 5 Health and Social Care Level 11545 Words   |  7 PagesCourse Title: Extended Diploma Level 3 in Health and Social Care Unit : 5 Assignment Title: Anatomy Physiology Scenario/Vocational Context: This unit introduces core knowledge of cellular structure and function, and the organisation of the body as a whole, and then builds on this to develop a more detailed knowledge of the fine anatomy and physiology of the systems involved in energy metabolism.

Energy is the strength and ability that is required in order to perform physical or mental activities. There are different forms of energy these consist of: magnetic, kinetic, heat, light, gravitational, chemical, sound, electrical, elastic and nuclear. The law, conservation of energy states that the total amount of energy within a system remains constant at all times, although energy within the system can beRead MoreNursing Research Critique Essay1624 Words   |  7 Pagesclinical trial that involved nine clinics in two health care systems in a Midwestern state and an exercise laboratory at a school of nursing. The study was conducted between November 2001 and July 2006. The design was appropriate for the research questions and covered an ample period with a long enough follow-up period. The method of sample selection was appropriate for this particular study. Data Collection The researcher adequately describes the sampling method.

Not only does the client benefit from a purely physical perspective, but the psychological and spiritual advantages are numerous. The concept of true health resulting from a correct equilibrium or balancing of this physical and spiritual energy has long been recognised by many cultures over a period of thousands of years, and is well documented in Egyptian and Roman civilization. With the advent of the Western mechanical medical model, the most important element in the healing process,Read MoreSocm Study Guide Essay30404 Words   |  122 PagesChapter 1 ELO’s Describe the basic functions of living organisms.
