Introduction

´╗┐This is my essay on how the body uses and stores energy metabolism. Firstly I will explain energy and what it is; I will then continue on to explain how and where the body gets and receives energy and how it is processed through the body. I will include how the respiratory system works and how it works along with energy metabolism and how the respiratory system receives and transports oxygen around the body. I will include in my essay how the digestive system works, and how food passes through the body. I will then go on to explain about the small intestine and how it works and also what it does to help with energy metabolism. I will then include what other systems work to help with energy metabolism. Towards of the end of my essay I will include my conclusions with the relevant facts I have produced through my essay. What is energy? Energy is known as power which can be used to move, work. How does the body use this energy? Every cell in the body relies and needs energy to survive, even just a twitch involves energy. In every cell in the body energy is stored and every second the energy is decreasing so you need to feed yourself so that energy is being supplied. ...read more.

Middle

Oxygen-rich blood from the lungs gets moved through a number of capillaries, which become the pulmonary vein. This vein delivers the oxygen-rich blood to the left side of the heart. The left side of the heart pumps the blood to the rest of the body. There, the oxygen in the blood moves from blood vessels into all the tissues. How important is the respiratory system for energy metabolism? The respiratory system is crucial for energy metabolism. The mitochondria are a cell in the body that is known as the power cell. This cell uses oxygen to convert energy so the rest of the cells can use it. This gives cells fuel for all the activities they need. What other systems help with energy metabolism? Cardiovascular system; When you breathe in air through your mouth and nose it travels to your lungs. Oxygen from the air is absorbed into your bloodstream through your lungs. Your heart pumps oxygen-rich blood through a number of blood vessels ? the arteries ? to tissues including your organs, muscles and nerves, all around your body. When blood reaches the capillaries in your tissues it releases oxygen, which cells use to make energy. These cells release a waste product called carbon dioxide which your blood absorbs and carries away. The used deoxygenated blood travels along your veins and back towards your heart. ...read more.

Conclusion

Microvilli are small projections of the mucous membrane of the small intestine walls. The microvilli give the small intestine walls a fuzzy appearance and are also known as the brush border. The small intestine has its own juices which it gets from the pancreas (alkaline) which helps to digest carbohydrates, the small intestine gets bile from the liver and the gallbladder this helps the small intestine to break down harder substances like fat. Pancreatic and intestinal enzymes help the small intestine turn proteins into amino acids. In the small intestine walls there are cells which when food gets pushed along inside the tube these cells get their sugar, vitamins and minerals. When the cells gather these nutrients they send them into your body for energy or to be stored. The small intestine doesn?t absorb water so it?s usually the only nutrient left when it asses into the large intestine. When the food is passed from the small intestine into the large intestine, the large intestine squeezes the remainder of the food to get the water out and leave it as a dry bundle of waste, which contractions in the rectum pushes the faeces out of the body (DeVault,K,and Rinzler,C,A.(2011). Conclusion: In the human body the respiratory system, cardiovascular system, the digestive system, the musculoskeletal system all work together for the body to receive the right amounts of energy it needs. All the cells in the body know what exact nutrient they need and to receive it they have to work together to achieve it. ...read more.

    Cell respiration is the process by which food is broken down by the body's cells to produce energy. Anaerobic cellular respiration occurs in the cytoplasm when no oxygen is present for the cell to continue respiration after glycolysis.
