Explain how the digestive, cardio-vascular and respiration systems are interrelated, and how they function in a specific task/job.
Internally in the human body, has to be well-controlled and organised with different progressive systems in which they must interconnect and interrelate in order to perform their role efficiently and successfully. There are different types of systems in the body (mainly 10) in which they all function in different ways and interrelate. An example would be the, nervous system which in fact regulates all functions within the body. Focusing on the main motive here, digestive, cardio-vascular and the respiratory are highly interrelated, in order to perform a specific function in the body.

Oxygen is breathe in and goes into the respiratory system. It then travels downwards along the lungs in the trachea. Once in the lungs, the gas moves into the alveoli and spreads in the alveolar wall. After that, it enters into the cardio-vascular system. Then oxygen joins together with haemoglobin which results in producing oxyhaemoglobin and is therefore transported around to cells in the body. By the cardio-vascular system, carbon dioxide is delivered and transported in a form of waste product in the erythrocyte. This has to be breathe out because acidosis would occur as excessive carbon dioxide existing in the blood causes that. The gas must evacuate from the blood in the same way oxygen entered into the blood and respiratory system is involved as the gas exit. Carbon dioxide spreads back into the alveoli and it is breathed out of the mouth by the respiratory system. It is very obvious that both of the systems are needed in order for gas exchange to occur. The interrelation of these systems is important because, if the body was not able to complete exchange of gas, cells in the body would be affected and it could even lead to death of
