In this assignment I will be explaining the physiology of two body systems, the cardiovascular system and the respiratory system in the relation to energy metabolism in the body. Energy metabolism is where energy is generated from nutrients and delivered to the organs around the body. Energy is needed in the body in order muscular movement, circulation of the blood, lymph and tissue fluid, breathing process, cell growth and repair, the transition of nerve impulses and for the building of different complex molecules.

The cardiovascular system

There are four major functions of the cardiovascular system, these include: the transportation of nutrients, gases and waste products around the body, the protection of the body from infections and blood loss, to help the regulation of the body’s temperature and to help maintain the fluid balance in the body.

The cardiovascular system consists of the heart, blood vessels and blood. The heart is a muscular pump which role is to force blood around the body via blood vessels, arteries, veins and capillaries. The heart is a double pump which consists of an upper chamber (the atrium) and a lower chamber (the ventricle). The right and the left side of the heart both have different roles, the right side of the heart pumps deoxygenated blood to the lungs which is needed for oxygenation via the veins, while the left side of the heart pumps oxygenated blood from the lungs to the rest of the body.
