The respiratory and circulatory systems are similar in that they:
add carbon dioxide |
|
deoxygenate blood |
|
transport nutrients |
|
transport oxygen |
Like the respiratory system, the circulatory system serves to transport oxygen throughout the body while removing carbon dioxide. In addition, the circulatory system transports nutrients from the digestive system.
