Body Systems and their role in Energy Metabolism and The Inter-relationship between Body Systems

“Explain the physiology of two named body systems in relation to energy metabolism in your body” Cardiovascular system The cardiovascular system has many different functions. The four major functions are to transport nutrients, gases and waste products around the body, to protect the body from infection and blood loss, to help the body maintain a constant body temperature and to help the body …show more content…

Your cardiovascular system couldn’t exist without the products of metabolism. Digestive system The digestive system is the group of organs that breaks down food so that the body can use it. It has many different functions and structures which help to break down food and many other different processes. One of the functions is the ingestion of the food which involves somebody taking in the food so it enters the body through the mouth where it is mixed with saliva. Digestion which involves two forms. One form is the mechanical breakdown of food by chewing and the action of muscles within the digestive tract and secondly the chemical breakdown of food. This involves changing the chemical composition of the food with the aid of digestive enzymes such as protein, carbohydrates and lipids. Digestive enzymes are special proteins that help break up large molecules of food into tiny molecules that can be absorbed and used by the cells in the form of nutrition. The digestive system consists of the digestive tract and its associated organs. The digestive tract is a tube through which food passes while it is broken down. The tract consists of the mouth, pharynx (throat), oesophagus, stomach, the small and large intestines and the anus. The associated digestive organs include the teeth, tongue, three pairs of salivary glands, the liver, the pancreas and the gall bladder. Structures within the mouth that aid mechanical digestion are the teeth
