    Does blood go from the pulmonary artery to the pulmonary vein ?

    And where does the blood go from the aorta?

    final question, when do the vena cava become involved (in the transport of blood)?

    CONFUSED

    Somebody help pleeease. Thankyou very much

    Think about it.

    Right Heart > Lungs > Left Heart > Body > Right Heart and so on.

    So, where does each of the vessels you mention fit into that cycle, which '>' are they represented by?

    Pulmonary circulation (heart-lungs): Blood leaves the heart (to be precise: right ventricle) through pulmonary artery and is oxygenated in the lung capillaries, after which it enters the heart (left atrium) through the pulmonary vein. Now the heart (left ventricle) provides the oxygenated blood an an additional boost so that it enters the systemic (body) circulation under high pressure. The aorta is the artery that is attached to the left ventricle and since it has to withstand high pressures, it is quite thick-walled.
    After exchange of substances (e.g CO2/O2) has took place, deoxygenated blood enters the right atrium through the vena cava. and enters the pulmonary circulation, when it is pumped to the lungs by the right ventricle.

    Hope you figured it out already

    It goes to the right atrium>right ventricle>pulmonary artery (blood taken to lungs and now becomes oxygenated > This oxygenated blood is taken from lungs to the heart via the pulmonary vein>left atrium> left ventricles>Aorta (which carries oxygenated blood to all parts of the body except lungs) > After exchange of substance, deoxygenated blood enter the right atrium and it all starts again

    I'd appreciate it if you could tell me whether this is right or not. Cheers

    Broadly yes.

    Remember that oxygenated blood is also taken to the lungs via the bronchial arteries, separate to the pulmonary circulation.

    Deoxygenated blood returns to the heart via the vena cavas, inferior and superior.
