The respiratory and circulatory systems are similar in that they:
add carbon dioxide |
|
transport oxygen |
|
transport nutrients |
|
deoxygenate blood |
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.

Which of these represents the path of blood flow through the heart?
left atrium → left ventricle → lungs → right atrium → right ventricle |
|
right atrium → right ventricle → lungs → left atrium → left ventricle |
|
right atrium → left ventricle → lungs → left atrium → right ventricle |
|
left atrium → right ventricle → lungs → left atrium → right ventricle |
To provide oxygen to the body, blood flows through the heart in a path formed by the right atrium → right ventricle → lungs → left atrium → left ventricle → body. When blood enters the right side of the heart it is deoxygenated. It enters the left side of the heart oxygenated after traveling to the lungs.
