Which of these does not contain oxygenated blood?
aorta |
|
right atrium |
|
pulmonary vein |
|
left 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.

Which of these represents the path of blood flow through the heart?
right atrium → right ventricle → lungs → left atrium → left ventricle |
|
left atrium → left ventricle → lungs → right atrium → right ventricle |
|
left atrium → right ventricle → lungs → left atrium → right ventricle |
|
right atrium → left ventricle → lungs → left atrium → right ventricle |
