Explanation:
The respiratory system allows for intake of oxygen, food 4 cells 2 absorb through the circulatory system.
once food is digested, it runs through the circulatory system as glycogen, (sugars). cells can readily absorb glycogen bcause of the fact it has smaller molecules 4 cells to absorb, to give them energy to function normally. respiratory system and the pulmonary aorta, distributes through the heart, absorbs food 4 heart, and distribute glycogen 2 rest of body, 4 cells 2 absorb 4 energy... hope this is helpful..

Answer:
Mr. B developed a neumotorax, therefore doctors inserted a chest tube to alleviate the pressure.
Explanation:
When a lung is punctured, air flows into the pleural space and because of the pressure it generates, it does not allow for the lung to expand normally. In this case, is best to insert a tube that enables air to leave the cavity and alleviates the pressure on the lung. In this way the lung can expand properly again.
