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.
Because they are also carrying oxygenpoor blood.
through your pulmonary artery and pulmonary vein.
By relaxing the blood vessels, antiangina drugs reduce the heart's work load and increase the amount of oxygenrich blood that reaches the heart.
Amphibians have red blood but it has a nucleus in the center of the cell unlike mammal red blood. Amphibians are cold-blooded.
To be rich in something means you have a lot of it, right? Well, for our blood to be rich in oxygen, we must have a lot of oxygen in the blood. Oxygen poor would be the opposite...minimal oxygen availability.
