Trace the movement of oxygenated blood in the body.

The deoxygenated blood comes to the heart through veins. It is oxygenated in the lungs and comes back to the heart. From heart oxygenated blood is distributed to all parts of the body.

Mechanism of blood moment:

The oxygenated blood leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. This blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. Left The ventricle pumps oxygenated blood to different parts of the body.
