In this assignment I will be explaining the physiology of two named body systems in relation to energy metabolism in the body, the Respiration system and the Digestive system. I will start off by giving a definition of energy metabolism in the body. Metabolism in the body is a collection of chemical reactions that takes place in the body’s cells. Metabolism converts the nutrients in the food that we eat in to essential energy which is needed to power all that we do, from something as little as thinking to growing physically or carrying out a physical activity. In our body’s, there are a specific protein which controls the chemical reactions of metabolism.
Our body requires energy for the body functions. This energy mainly comes from the carbohydrates and fat that we take as food. Carbohydrates are decayed into glucose, glucose is soluble in blood. It is transported by the blood cells to various parts of the body where it reacts with oxygen in a series of steps producing carbon dioxide, water and energy.
Glucose + Oxygen →Carbon Dioxide + Water + Energy
The burning of food in the cells results in the free of energy which is called respiration. Carbon dioxide and water, which are formed during respiration, are transferred through various organs of the body. The energy released in respiration fulfils the energy needs of the body.
The respiratory system comprises of the nose, mouth, throat, larynx, trachea, bronchi and lungs. The function of the respiratory system is to facilitate gaseous exchange to take place in the lungs and tissue cells of the body.
“Your metabolism is tied inextricably to your respiratory system, because the respiratory system is responsible for bringing in the oxygen you need to burn nutrients for energy, and for clearing out certain metabolic waste products. You can't affect your metabolic rate through your
