Discuss the roles of energy in the body
In this assignment I am going to discuss the roles of energy in the body systems in relation to energy metabolisms, also explain the roles energy metabolisms have on the body system. Energy metabolisms- The Basal Metabolic Rate (BRM) refers to the amount of energy that our body needs to maintain homeostasis. Our BMR is determined by our total lean mass, expessically the muscle mass as it requires a lot of energy. Energy metabolism is all chemical reactions occurring in the human physiology which will involve releasing or using energy from chemical substances.
The roles of energy in the body is to extract oxygen from the atmosphere and diffuse it into our bloodstream. The energy is vital from moving the body muscles in activities which are needed to be done every day. Aerobic (with oxygen)- Aerobic metabolism uses oxygen to create energy from carbohydrates, fats and proteins. Aerobics metabolisms is a main system used after two minutes of exercise. Catabolism- The metabolic breakdown of complex molecules into simpler ones, which often results in a release of energy.
Anaerobic metabolism is responsible for creating energy for movements without the use of oxygen. During exercise individuals rely more on anaerobic metabolism for energy. The body systems are….. The cardiovascular system- The cardiovascular system has to provide oxygenated blood to the rest of the body at a constant speed to maintain enough energy in order for it to work. Enough energy has to be produced by the oxygen that is taken in. The cardiac output is very vital as it is connected to the energy production.
Tissue yields are energy supplies where poor tissue perfusion result in critical shortages of energy and may often cause a diminished function in the body. Digestive system- Apart from breaking down and absorbing nutrients, the digestive system also converts foods into energy to help power muscles to contain good health. We need food to fuel our bodies for energy. These are put into their simplest forms. Glucose (sugars) Amino acids (makes up the proteins) Fatty acids ( makes up the fats) This is all broken down to give energy to every cell in our body.
Analyse how two named body systems interrelate to perform a named function/ functions. In this assignment I am going to analyse how the two named body systems for example circulatory system and respiratory system interrelate to performed named functions. The circulatory system and the respiratory system work closely together to ensure that organ tissues receive enough oxygen. Oxygen is required for cellular functions. The air that we breathe in is held in the lungs which is then transferred in to the blood.
The blood is then circulated back up to the heart which is then pumped from the oxygenated blood from the lungs to the body. Additionally, the two body systems work together to remove the carbon dioxide, which is a metabolic waste product. Anabolism and catabolism energy make sure that energy breaks down. This energy is reused to keep the body working correctly. While the cardiovascular and respiratory system work together with energy metabolism. The respiratory system takes in oxygen from the lungs, which is then placed in the circulatory system which carries the nutrients around organs and cells in the body.
Both systems in the human body work together to maintain homeostasis. Homeostasis is how the body keeps conditions inside it the same. For example 1. The amount of water inside the body 2. And keeping the body temperature at 37 degrees Homeostasis also comprises blood, tissue fluid and body cell contents and all the metabolic processes which take place. One way of getting homeostasis is through the rate of breathing. For example, if during exercise the levels of CO2 increases or if more oxygen is needed by the body the breathing rate of the individual will increase.
