WebIn mammals, the highest concentration of CO₂ is found in the venous blood, which returns to the heart and is then pumped to the lungs for oxygenation. Therefore, blood entering the pulmonary capillaries, which is deoxygenated blood coming from the systemic circulation, will have a higher PCO₂ than other regions of the circulatory system. WebThe circulatory system is effectively a network of cylindrical vessels: the arteries, veins, and capillaries that emanate from a pump, the heart. In all vertebrate organisms, as well as some invertebrates, this is a closed-loop system, in which the blood is not free in a cavity.
