D1 – Analyse how two body systems interrelate to perform named functions 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. Energy metabolism comes in different types such as Anabolism and Catabolism energy. They all make sure that energy breaks down and is reused to keep the body working correctly for example muscle mass and increase in bone. With the cardiovascular system and respiratory system working together with energy metabolism is when the respiratory system takes in oxygen from the lungs and then it is placed in the circulatory systems carries the and nutrients around the organs and cells in the body. Also the cardiovascular and the respiratory system both work toward the same goal: getting oxygen to tissues and getting carbon dioxide out. The respiratory system is involved in supplying oxygen to the blood and removing carbon dioxide. When the heart receives blood that is low in oxygen and high in carbon dioxide, it pumps it to the lungs via the pulmonary arteries. When the lungs expand and get fresh air from the environment, oxygen is transferred into the low-oxygen blood, which also then sends some of its carbon dioxide back into the lungs. The main function of the respiratory system is gaseous exchange. This refers to the process of Oxygen and Carbon Dioxide moving between the lungs and blood. This occurs during gaseous exchange as the blood in the capillaries surrounding the alveoli has a lower oxygen concentration of Oxygen than the air in the alveoli which...
