Explain the Physiology of Two Named Body Systems in Relation to Energy Metabolism in the Body
I am going to explain the physiology of the respiratory and cardiovascular system in relation to the energy metabolism in the body.
Energy metabolism is where the nutrients oxygen and glucose are took in and delivered the organs. Energy is needed in order for our body to be able to function. Energy helps break down molecules and to build new molecules.
The cardiovascular system consists of the heart, blood and blood vessels. The cardiovascular system is the major transport of materials to and from the cells. Blood is carried from the heart around the body via the arteries and the blood is then carried back to the heart via the veins. The …show more content…
Oxygen is needed to burn nutrient molecules. To do this you use aerobic metabolism; this process requires oxygen which is provide by the lungs. There are two different types of respiration that help with energy production; they are aerobic and anaerobic respiration. An example of aerobic respiration is when you are exercising at a steady pace and the cardiovascular system is able to provide the muscles with oxygen that they need; the equation for aerobic respiration is, glucose + oxygen = energy + carbon dioxide + water. An example of anaerobic respiration is when you are exercising a higher intensity and the cardiovascular system is unable to supply enough oxygen to your muscles. As there is no oxygen attainable glucose is therefore burned in order to produce energy and lactic acid; the equation for anaerobic respiration is, glucose = energy + lactic acid. Digestion is a process of food breakdown which allows nutrients to be used in the body for the production of heat and energy. The digestive system works to provide the body with energy by breaking down food molecules in order for the body to use it. The food molecules that have been broke down for energy helps with essential body functions. The useable energy helps with physical activities such as walking and playing sports as well as working, talking and important activities breathing and thinking. The food we intake contains a chemical energy and when it’s released by
