What circulation brings carbon dioxide-filled blood to the lungs.?

Answer 1

The systemic circulation brings oxygen-filled blood to the body tissues, and returns carbon-dioxide filled blood to the heart. The pulmonary circulation brings carbon-dioxide filled blood to the lungs.

Answer 2

When blood is pumped out of the heart, through the pulmonary artery, and to the lungs, it has a higher concentration of carbon dioxide because there is more carbon dioxide bound to the hemoglobin in red blood cells to form carbaminohemoglobin.

When this carbaminohemoglobin-rich blood reaches the alveoli of the lungs, the carbon dioxide is released upon expiration (breathing out), and fresh oxygen can be taken in upon inspiration (breathing in), where it passes back across the alveoli, into the red blood cells, and binds with hemoglobin to form oxyhemoglobin (oxygen-rich hemoglobin), which has a distinctive reddish color. That oxygen-rich blood returns to the heart via the pulmonary vein, where it can be redistributed throughout the body by pumping through the heart and out the aorta.

Answer 3

The heart pumps oxygen into the blood and collects carbondioxide from it to be expelled through the lungs.
