Interrelation of Circulatory and Respiratory Systems

- analyse how two body systems interrelate to perform a named function/functions

In the body, bodily systems work hand in hand with one another to perform key functions. The circulatory system is a major system of the body, it comprises of the heart and three types of blood vessels know as the capillaries, veins and arteries. The heart is a muscular pump which has the duty of pumping blood so it is carried to the blood vessels, until it reaches the chambers in the heart. These capillaries carry oxygenated blood via the bloodstream so that organ tissues recive oxygen. The capillaries will take in any excess amount of carbon dioxide; this is carried to veins so the blood can be transported back into the heart and then the lungs.

The respiratory

both these sysmtems work with one another to ensure that organs tissues in the body are supplied with an adequate amount of oxygen, and that carbon dioxide can be removed. firstly through the respiratory system, oxygen is inhaled through the nose and mouth, the oxygen is will travel down the trachea, the rachea divides into the bronchial tubes which enters the lungs. the bronchi divides into smaller branches known as the bronchioles, which have tiny air sacs called alveoli on the end. The alveoli is surrounded by thin blood capillaries, the wall of the capillaries is a single layer of cells. These thin walls allow gas exhange to take place. Oxygen will be diffused in the capillaries and will go into the red blood cells, where it will then be transported back to the heart. carbon dioxide will be diffused though the capillary walls into the alveoli, in an opposite path than oxygen. carbon dixoxide will be released in the lungs and through exhalation the carbon dioxide will be removed.The right atrium of the heart will supplied with de-oxygenated blood by the superior and inverior vena cava. The right atrium will pump the de-oxygenatd blood via the atrioventricualr valve until it reaches the right ventricle. the right ventricle will pump the de-oxygenated blood via the pulmonary semi-lunar valve, which will carry the blood pass through the pulmonary arteries unti it reaches the lungs. these veins from the lungs will carry oxygenated blood to the right atrium. the right atrium will now pump this fresh oxygenated blood past the aventricular valve so it can enter the left ventricle. the left ventricle the thickest out of the four chambers and will pump, so that oxygenated blood is supplied to all the organ tissues in the
