The circulatory system is containing blood that is useful to transport oxygenated and deoxygenated hemoglobin to various tissue s& cells as a result oxygen is delivered to the cells to carry out cellular respiration followed by expulsion of CO2 from cells into the circulatory system. This circulatory system is going to transport deoxygenated blood to lungs to purify blood.
