Body System In Relation To Energy Metabolism

The cardiovascular system is the process of the heart pumping the blood around the body through blood vessels, arteries, veins and capillaries. The main functions of the system are to transport materials to and from the cells around the body, to assist in temperature, to keep the levels of fluid in the body at the correct level, to distribute heat around the body and to defend the body. This system is the heart, which is a muscle that pumps blood around the body through arteries, veins and capillaries. Blood transports oxygen to the body cells which helps them to metabolise energy in the body. During this process the blood is also getting rid of any waste products of respiration, carbon dioxide and water. Blood also helps to supply heat, hormones, nutrients, salts and urea around the body. The heart is placed in between the lungs which is protected by the rib cage and is the size of a fist.

The respiratory system and the cardiovascular system work together by oxygen being inhaled by the mouth and nostrils and then the oxygen enters the respiratory system. When the oxygen enters the respiratory system, oxygen enters the alveoli which are located in the lungs and then it diffuses through the alveolar wall. After when this process is complete, it enters the cardiovascular system. The oxygen is then mixed with hemoglobin, which forms oxyhaemoglobin. The blood is then circulated all around the body. While the blood is mixed with the oxygen, a waste gas gets produced, which is carbon dioxide. The excess gas then exists out by going through the respiratory system and then it is exhaled out from the mouth.

Our cardiovascular system is composed of the heart and blood vessels. The main purpose of this system is to transport substances throughout the body. Even though transportation is the main function of the cardiovascular system, it is not the only function. Along with transportation we have protection and regulation.

In this task I will be examining how the different body systems use energy and why the body needs energy. I will also be analysing cellular respiration which is the process in which energy is made, along with the by-products and anabolism and catabolism. Later on in this task I will be analysing how ATP is used in muscle action, protein production and how we as mammals use the energy released as heat.

P4- Explain the physiology of two named body systems in relation to energy metabolism in the body.

First the air that’s breathed in travels down the trachea, into the lungs, through the bronchioles and into tiny air sacs called alveoli. The oxygen in the alveoli diffuses into the capillaries, where there’s a lower concentration of oxygen. The thin walls of the capillaries allow the oxygen to diffuse through into the blood. The circulatory system then carries the blood around the body, supplying cells with the oxygen required for energy; allowing them to function. Glucose is also needed, which comes from the digestive system. Glucose is made from the sugary or starchy foods consumed. It start off in the mouth where the salivary glands produce saliva, which contains amylase which breaks down the sugars and starch. It then travels to the stomach, where it’s mixed with other enzymes and fluids, becoming a mixture known as chyme. Chyme, then travels to the small intestine where there are tiny, finger-like structures called villi on the surface walls of the intestine. Villi, are one cell thick making it easy to absorb particles, such as glucose, into the blood from the chyme which is passing through the small intestine. Once in the bloodstream, the circulatory system transports the glucose to cells to be used for energy.

The circulatory system and the respiratory system work closely together to ensure that organ tissues and systems receive enough oxygen. Oxygen is required for cellular functions such as cell respiration. This is so the body’s organs and cells can work at fully; it is done by releasing chemical energy with in stored foods. The air breathed in and held in the lungs is transferred to the blood. The blood is circulated by the heart, which pumps the oxygenated blood from the lungs to the body organs and returns with deoxygenated blood.

Explain the physiology the cardiovascular and the digestive system in the body in relation to energy metabolism in the body. Discuss the role of energy in the body and analyse how those two body systems interrelate to perform a named functions. For distinction analyse

The heart is a major organ in the body, this organ pumps blood around the body, through veins, capillaries and arteries. The blood carries oxygen to our cells and also carries waste products which include water and carbon dioxide, which are products of respiration. Blood also helps spread out salts, enzymes, urea, nutrients, hormones and heat across the body.

Metabolism is a chemical process that converts fuel from food into energy needed for the body’s activities. For example, thinking, running and jumping etc. are all an example of the bodies activities.

My two chosen systems I will be writing about is the cardiovascular system and Digestive system.

The Circulatory system is responsible for the transport of blood throughout the body. The Circulatory system has many organs. The main components are the heart, the blood, and the blood vessels. It also consists of arteries, arterioles,

The respiratory system and cardiovascular work closely together to make sure that organ tissues obtain sufficient oxygen. Oxygen is vital for cellular functions. The air inhaled in and kept in the lungs is transported to the blood. The blood is circulated by the heart, which pumps the oxygenated blood from the lungs to the body. Moreover, the two body systems work together to get rid of waste products such as carbon dioxide. They perform in order and are frequently referred to as the cardio-respiratory system, a combined name that highlights their close connection. After carbon dioxide and oxygen move across the alveolar wall in the lungs, the carbon dioxide-poor blood, oxygen-rich moves through pulmonary veins to the left atrium of the heart.

The respiratory system major role is to supply the body with oxygen and dispose of carbon dioxide. The body cells require a continuous supply of oxygen and as the cells use oxygen, they produce carbon dioxide which is a waste that the body needs to get rid of. There are four distant process that must occur during respiration which are Pulmonary ventilation, External respiration, Transport of respiratory gases and Internal respiration. The pulmonary ventilation is commonly called breathing and it’s the tide like movement of air into and out of the lungs. The external respiration is the gas exchange between the blood and chambers of the lungs. The Transport of respiratory gases is the transport of respiratory gases between the lungs and tissue

The cardiovascular system is the system of the body which includes the circulatory system and your heart. This system has three functions. Its first is transportation where it is responsible for pumping blood to the organs, tissues, and cells of your body in order to transport a proper amount of oxygen and nutrients to every cell as well as remove the carbon dioxide and waste products made by some cells. This is done by using one of the strongest muscles and the hardest-working organ in the body-- the heart. Blood is pumped through this organ into the major blood vessels located at the base of the heart. The major vessels include the vena cava, aorta, pulmonary trunk, and the pulmonary veins. Although the heart is no bigger than the average
