mixed venous blood

mixed venous blood

blood that is composed of the venous blood from the heart and all systemic tissues in proportion to their venous returns. In the absence of abnormalities, mixed venous blood is present in the main pulmonary artery.

mixed venous blood

the blood flowing into the right side of the heart and thence out to the lungs in the pulmonary artery, which is a mixture of venous blood from the whole of the systemic circulation (i.e. from all parts of the body except the lungs). May be sampled by cardiac catheterization, for estimates of whole body arteriovenous difference. See also oxyhaemoglobin dissociation curve.
