Respiratory System Interrelated

The circulatory, digestive and respiratory system are interrelated because although each of these systems have their own individual purposes. The digestive system takes the food that is eaten and breaks it down into smaller molecules that can be absorbed into the bloodstream. Cells can then use the molecules for their maintenance. The respiratory system takes in oxygen from the atmosphere and then passes it into the bloodstream in order for it to be delivered to all the cells in the body. The circulatory system delivers the oxygen to all the cells but is also picks up the carbon dioxide and waste from the cells. The carbon dioxide is taken back to the lungs. The carbon dioxide is diffused from the blood into the lungs and is then released into the atmosphere through exhalation.
These systems are then interrelated because the digestive system breaks down food by muscles contracting. The smooth muscle present in the stomach churns the
Also for the muscle within the respiratory system to be able to inhale they need to be able to contract and this can only happen if the muscles are provided with fuel. This fuel is provided to the cells of the respiratory muscles by the products of the digestive system. All of the systems require their cells to respire. This happens when the digestive system produces oxygen and glucose, the process of respiration can occur. Alongside the products being used products are being made these are carbon dioxide and water. They are transported through the body using the cardiovascular system and they are brought to the respiratory system so the carbon dioxide can be
