The circulatory system, also known as the cardiovascular system, contains a group of organs that work together to circulate blood and transports nutrients, carbon dioxide, and oxygen around the body.
The respiratory system is a group of organs that allows organisms to breathe, also called respiration. It is a system that is responsible for inhaling oxygen and exhaling carbon dioxide. When we inhale the red blood cells carry oxygen from the lungs to different parts of the body and they also carry the carbon dioxide back to the lungs so it can be exhaled.
The cardiovascular system is related to the respiratory system, we know this because when we inhale oxygen it goes into the lungs through the trachea. The oxygen diffuses through the alveoli walls and the capillary walls and enters the circulatory system, it then is carried by blood to the cells in the body. The carbon dioxide, which comes from the waste of the cells, is then transported with the red blood cells back to the lungs. It has to leave the blood the way the oxygen entered, therefore it must diffuse into the alveoli and capillary walls so that it can be exhaled from the nose. These two …show more content…
There are many nutrients that are produced by the digestive system that helps keep the heart rate under control. These nutrients are crucial for the whole body, so once the blood absorbs them it carries it to where it is needed in the body. The blood vessels then expand in order to supply the digestive system with more blood and the speed of digestion is controlled by some chemical signals that are carried by the circulatory system. The digestive system produces toxins from the digestion of foods, these toxins are moved to the kidneys by the circulatory system so that it can be removed from the
