The circulatory and respiratory systems work together to get oxygen to cells. Oxygen transfers from the respiratory to the circulatory system at the capillaries surrounding the alveoli.
The lungs are part of the respiratory system! they help the circulatory by giving oxygen, but they are just respiratory.
They both work to provide oxygen to the cells. The respiratory system provides air to the circulatory system. The the blood from the circulatory system delivers oxygen to the cells. For more help search on the internet. :)
the (circulatory) respiratory system (blood flow carries oxygen)

The respiratory system transfers oxygen from the lungs to the circulatory system. The circulatory system transfers the carbon dioxide into your lungs and we then breathe it out.
The circulatory system and respiratory system are interlaced. The circulatory system much deliver nutrients to all the parts of the body. Every single part of the body needs oxygen, so the circulatory system takes the oxygen collected by the respiratory system and delivers it to the rest of the body.

The respiratory system provides oxygen so the body can "burn" (oxidize) the food that is brought into the body through the digestive system. The circulatory system brings nourishment to all cells of the body. The circulatory system exchanges critical gases with the respiratory system; unneeded carbon dioxide is exchanged for much needed oxygen.
The respiratory system helps the circulatory system. circulatory system
Because when mammals breathe (Respiratory) it causes their blood to circulate (Circulatory) ad they need their blood to circulate to live. Hope this was helpful. :)
