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 capillaries connect the arteries to the veins; the function of the capillaries is too supply the cells with nutrients and oxygen. The cardiovascular system is responsible for the transport of oxygenated blood around the body. It will transport these to the cells and collect the deoxygenated blood which is ready for the excretion from the cells. The cardiovascular system will deliver the nutrients oxygen and glucose via the blood stream. Oxygen is need for aerobic respiration to occur.

The Cardiovascular System

The function of the respiratory system is to remove carbon dioxide and water from the body, also to maintain an oxygen to supply to each of the cells. In the respiratory system there is internal and external respiration. The internal respiration is carried out in the body cells whereas external respiration consists of blood transport, breathing and gaseous exchange. The respiratory system contains alveoli which allow the diffusion of oxygen into the blood stream and carbon dioxide out of the blood stream. This process allows the respiratory and cardiovascular system to work together to transfer the nutrients. Internal respiration is also known as cell respiration where the cells are provided with energy in order to perform...
