UNIT 5 – ANATOMY AND PHYSIOLOGY FOR HEALTH AND SOCIAL CARE
TASK 4: Analyze how two body systems interrelate to perform named function/functions. Discuss the role of energy and explained the physiology of two named body systems in relation to energy metabolism in the body.

I am going to explain the physiology of the respiratory system and the cardiovascular system in relation to the energy metabolism in the body. Energy metabolism takes in nutrients, oxygen and glucose as well as delivering the nutrients to our organs. In order for our body to function we need energy, as it helps to break down molecules and build new molecules. The cardiovascular system is made up of the heart, blood and blood vessels. Blood is carried from the heart around the body via the arteries; the blood is then carried back to the heart via veins. The capillaries connect the arteries to the veins and their role is to supply cells with nutrients and oxygen. The cardiovascular system is accountable for transporting oxygenated blood around the body to the cells then collecting the deoxygenated blood which has been excreted from the cells. The cardiovascular system delivers the nutrients, oxygen and glucose via the blood stream. For aerobic respiration to occur we need oxygen.
The respiratory system removes carbon dioxide and water from the body as well as maintaining an oxygen supply to all of the cells. There are both internal and external respirations. Internal respiration, also known as cell respiration, is where the body’s cells are provided with energy in order to perform tasks, whereas external respiration is where blood is transported, breathing and gaseous exchange. The respiration system contains alveoli which allow diffusion of oxygen into the blood stream and carbon dioxide out of the blood stream. This process allows the respiratory system and cardiovascular system to work together to transfer nutrients.
