Circulatory System
Platypus have a closed, double looped circulatory system. Like humans, they have a heart, blood vessels, veins, arteries, and lungs to provide oxygen to the blood. The lungs provide oxygen to the blood, which then travels to the left atrium and the left ventricle. After this, the blood enters the rest of the body and loses oxygen. The deoxygenated blood then goes back to the heart into the right ventricle and the right atrium, then is pumped back into the lungs to be oxygenated. This cycle is continuous.
