“Explain the Physiology of Two Named Body Systems in Relation to Energy Metabolism in Your Body”
Cardiovascular system
The cardiovascular system has many different functions. The four major functions are to transport nutrients, gases and waste products around the body, to protect the body from infection and blood loss, to help the body maintain a constant body temperature and to help the body maintain fluid balance.
The main structures include the heart, the blood vessels and the blood. The heart is the key organ in the circulatory system. Its main function is to propel blood throughout the body.
Energy metabolism is generally defined as the entirety of an organism's chemical processes. These chemical processes are categorized as being either catabolic or anabolic. Energy is needed in order for our body to be able to function. Energy helps break down and to build new molecules. The cardiovascular system transports the oxygen and glucose to the cells and transports the waste products such as carbon dioxide and urea away from the cells to other parts of the body like the lungs or the kidneys. A.T.P (adenosine triphosphate) is a chemical energy that you produce when you burn nutrient molecules. The main source of energy for living organisms is a sugar called glucose. In breaking down glucose the energy in the glucose molecule's chemical bonds is released and can be harnessed by the cell to form ATP molecules. Catabolism is the set of metabolic pathways that breaks down molecules into smaller units to release energy. In catabolism, large molecules such as lipids, nucleic acids and proteins are broken down into smaller units such as fatty acids and amino acids. When food is broken down energy is released as the foods molecules’ bonds are broken. Then this energy is used to reform the bonds that have been broken so that ATP can be recreated. More energy can be obtained when oxygen is present and the process proceeds on aerobically. The aerobic production of ATP...
