Why must the circulatory and respiratory systems work together?
The circulatory and respiratory system must work together, in order to provide oxygen to all the cells of the body.
The cells perform the process of cellular respiration through Kreb's cycle. Kreb's cycle is involved in the production of ATP and requires oxygen for its functioning. This oxygen is carried to the different cells of the body through the circulatory system. The circulatory system transports oxygen by binding oxygen with hemoglobin in the red blood cells. When the blood reaches the cells, oxygen is taken up the cells and carbon dioxide is taken up by the blood.
The deoxygenated blood is then taken to the lungs for oxygenation.
The respiratory system consists of lungs and diaphragm. The respiratory system carries out the function of bringing oxygen to the lungs and removing carbon dioxide from them. Once the lungs get oxygen, it is supplied to the blood stream for distribution to all the cells of the body.
