Heart with blood flow

3D Model

The model depicts blood flow through the heart. It shows how deoxygenated blood enters the right atrium (blue arrows), travels through the right ventricle and is pumped to the lungs, where it becomes oxygenated. Then, it travels through the pulmonary veins into the left atrium (pink arrows), goes through the left ventricle and is pumped into the aorta, from where it will travel to all corners of the body, to supply tissues with oxygen.
