How to flow Impure Blood in our body system? How to prepare Impure Blood? how to convert Impure Blood into Pure Blood?
I could not interpret your query. However, if you are asking about the flow of impure blood (blood contains metabolic wastes and carbon dioxide) in our body, then the answer is as:
The impure blood (blood contains carbon dioxide and metabolic wastes) flows from body tissues to heart through veins. The heart pumps this impure blood to lungs for removal of carbon dioxide and to kidney for removal of nitrogenous wastes. The purified blood returns back to the heart where from it is pumped back to all body parts through arteries.
