Both circulatory and respiratory systems work together to move oxygen into and throughout the body.
Oxygen is an important component for energy generation in the cells of the body. Hence, it must be in constant supply to the body.
The respiratory system ensures that oxygen gets into the body through the lung.
From the lung, the oxygen dissolves into the blood through the vessels that line the lung.
Once in the blood, the circulatory system takes charge and ensures that the dissolved oxygen is transported to all the parts where it is needed.
