Respiratory system question?

Does the de dioxygenated blood produced by the muscles return directly to the heart first before it it then carried to the lungs for oxygenation where co2 can be expired?
Or does it go directly to the lungs after muscles have the waste product.
I believe all oxygenated and dioxygenated blood need to pass the heart before it transported to the lungs right?

  • Yes. If I could, I would draw you a diagram. Basically:

    - Deoxygenated blood is pumped (through the pulmonary artery) to the lungs, where it's infused with oxygen.

    - Oxygenated blood is pumped back to the heart (through the pulmonary vein).

    - The heart pumps the oxygenated blood to the various places in your body that need oxygen (through the aorta).

    - The deoxygenated blood is pumped (through the vena cava) back to the heart.

    And the cycle continues.
