How are the respiratory and digestive systems linked?

Answer 1

well..i know that the cirulatory system and the respiratory system are dependent on each other because as you breath in, the air goes into your lungs where it passes through the complex alveoli system which connects to the heart. the heart then pumps the oxygen rich blood to all parts of the body. once that's done, the oxygen poor blood comes back to the heart, passes back through the alveoi exchange and then you breath out co2. and i think that the digestive system is related to the circulatory system also. this is because when the "food" gets down to the small intestine, the nutrients are sucked out of it and those nutrients are absorbed into the blood stream in which the heart pumps these nutrients to all parts of the body and the cells take nourishment off of it. but i cant really see how the digestive and the respiratory systems are interlated...

Answer 2

The digestive system digests foods which are broken gown into things like glucose and the glucose is then circulated through the blood and to the muscular system which is the then used for aerobic respiration, for aerobic respiration you muscles need oxygen, the oxygen is carried to other parts of the body to certain cells, the cells give off carbon dioxide with is then take back to the lungs and the excretory system gets rid of the carbon dioxide. This is how they all work together.
