in diagram of the heart, the right side is colored blue to indicate its low in oxygen and high in ____________

marissa [1.9K]

Answer:

<h2>CO2 (Carbon dioxide)</h2>

Explanation:

The right side is collored blue to indicate that the blood pumping through here is low on oxygen, but high in carbon dioxide. Because the blood is so low on oxygen, and high in carbon dioxide (a byproduct of Cellular Respiration), the blood will be pumped to the lungs where the CO2 is removed, and oxygen is taken in.
