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.
Digestive system …show more content…
functions to take in and acquire the important nutrients which are needed to keep, maintain and control other systems in the body. There are enzymes (amylase, protease, and lipase) which are secreted in the digestive system, and all have a specific job in breaking down food from starch into glucose, proteins into amino acids, and fats into fatty acids and glycerol.
Respiratory system also functions to breathe in (inhale) oxygen and breathe out (exhale) carbon dioxide as waste product. In the mouth and the nostril, oxygen is breathed into the lungs. Then the gas (oxygen) spreads (diffuses) in the walls of the alveolar and goes into the erythrocytes (red blood cells). Carbon dioxide passed back within the erythrocytes spreads back in the alveolar walls and then breathe out through the mouth.
Cardio-vascular system has a function in the body by circulating blood around. The amounts of blood that is being circulated include gases, nutrients and waste products. The main organs in the operation (process) are the heart, blood, arteries, and the lungs.
On the above description given about the respiratory and the cardio-vascular system; it can be examine and evaluated that both of the systems are interrelated to perform a specific job.
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
cells.
Moving to the respiratory and the digestive system, they are both interrelated to perform a defence and protection mechanism. For example, once a micro-organism has magnificently and effectively entered the body, cells such as goblets along the respiratory tract have the capability to make a bigger and greater yield of mucous. The mucous is a defensive liquid (always sticky) in which has the skill to collect micro-organism which binds with the substance. In the trachea, cilia slide the substance (mucous) near to the entrance of the oesophagus. Then the mucous is transported in the tube and into the stomach which contains a strong acid (hydrochloric acid). To support the respiratory system, the digestive system supplies the diaphragm with the main nutrients essential to enable breathing.
Both of the systems provide the important products to achieve aerobic respiration. The first part of the equation of the aerobic respiration (glucose + oxygen), are formed by these systems; by the respiratory system oxygen breathed in and by digestive system glucose is broken down. Without the digestive and the respiratory systems interrelating, respiration process cannot be successful.
