Oxygen poor. It carries oxygen poor blood from the right ventricle of the heart to the lungs to be oxygenated.
"Oxygen rich" means lots of oxygen. If the air in a room is "oxygen rich" things will burn better. "Oxygen poor" means there isn't much and "oxygen starved" means there is none or almost none.

OXYGEN
I think you meant "through the body". if that is so: the heart does, it pumps oxygen poor blood to your lungs. then the blood absorbs the oxygen with the help of diffusion. this is like smoke: smoke doesn't stay together, it goes to places where no smoke is. the same counts for your blood, there is no oxygen in it so the oxygen goes into your veins. then the heart pumps it around the body until the oxygen is used up. the process will start over again.Your heart.

Oxygen poor. It carries oxygen poor blood from the right ventricle of the heart to the lungs to be oxygenated.
the quality of our blood that rich with oxygen will become low
Blood entering the left ventricle is rich in oxygen. In contrast, oxygen-poor blood enters the right ventricle.
Oxygen rich - the opposite of what the majority of veins are in the body.
poor
Dark red blood is oxygen-poor. Bright red blood is oxygen-rich.
poor
Oxygen-poor blood is dark red; oxygen-rich blood is bright red.
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
The amphibian's heart does pump out a mixture of oxygen-rich and oxygen-poor blood. They are vertebrates, and this is how vertebrates' circulatory systems work.
