Some facts about Blood

Here we are going to discuss about the blood circulation. The unpurified blood is sent from the right side of the heart to the lungs, and then it is purified and again sends back to the left chamber of the heart. From there only, the purified blood will sent to all other parts of our body through the Arteries and then it comes back as unpurified blood to the right chamber of the heart through Vein.

The blood from the artery is changed to vein through miniscule capillaries. The cardial valves in the chambers of the heart perform the unidirectional circulation of blood by opening the valves unidirectionally.
