In this current era, where people are in need of blood at any point of time, 'Blood Banks and Centers' are a step away only. Human blood collected from different blood donation camps ,in Mounds View, is stored in blood banks. Apart from blood, it also stores blood plasma and other blood constituents. Although most of the hospitals in Mounds View maintain their own blood reserve, it is not assured that one will get any type of blood at any point of time over there and here's the role of blood banks. An anticoagulant is added in the blood to prevent clotting since the whole blood can be kept for maximum of 21 days. The other constituents of blood, like plasma and fluid portion of the blood are frozen or dried and stored separately. For some critical treatments, such blood is required which is rich in stem cells. The processing and storing is very costly for these type of blood. Very few blood banks and centers save this kind of blood, which is also known as umbilical cord blood. There are two kinds of umbilical cord blood banks: private and public.
