Discuss the Physiology of the Three Named Body Systems in Relation to Energy Metabolism

Topics: Digestion, Metabolism, Blood Pages: 2 (401 words) Published: October 15, 2012
The three systems in our body that work together are cardiovascular, respiratory and digestive systems which supply energy to the cells of the body. I will be describing their role of energy in the body system also I am going to explain the physiology of the three named body systems in relation to energy metabolism. Respiratory System

The respiratory system consists of tissues and organs in your body which are formed into groups. The system includes airways, lungs, blood vessels and muscles attached to work together so an individual can breathe. The respiratory systems primary function is to supply oxygen to all the parts of the body. When a person breathes, they inhale oxygen and exhale carbon dioxide. The respiratory system and digestive system work together in various different ways. The respiratory allows the digestive tract to function and same for the digestive system. Also they both work together to provide energy to body cell. The metabolism is tied to the respiratory system because the system is responsible for providing oxygen in one’s body. Digestive System

The digestive system functions in a way which is firstly ingestion (in taking food), digestion (breaking down the food), absorption (extracting the nutrients from food) and finally defection (waste of food). The digestive system is a group of organs that breakdown the chemical components of food, with fluid (digestive juices) into tiny nutrients which can be absorbed to generate energy. The mouth, pharynx, oesophagus, stomach, liver, gall, bladder, jejunum, ileum, and colon break down the food. Cardiovascular System

The cardiovascular system consists of the heart, blood, blood vessels and lymphatic system. The purpose of the system is to circulate oxygen to your body cells nonetheless; it also has to circulate nutrients. Your blood then returns the waste products including carbon dioxide of different metabolic reactions to the lungs and to the excretory organs. The cardiovascular system...
