Can we create artificial blood that works just as real blood for all patients?
No, we cannot currently create artificial blood that works just like real blood for all patients; "The Quest Continues" to develop it. We still depend on donated blood from healthy individuals for transfusions during emergencies, surgeries, or serious illnesses.
Donated blood is tested, its blood group is identified, and it is separated into components like plasma, platelets, and blood cells via centrifugation. These components are then stored safely in blood banks.
Since blood is a colloid—neither a solution nor a true suspension—its complex nature makes it difficult to replicate artificially. Therefore, natural blood donation remains crucial for patients.
Explanation
The textbook poses this question under the heading 'The Quest Continues', implying that a perfect artificial blood substitute for all patients does not yet exist. The context emphasizes the current reliance on blood donation and the complex nature of blood as a colloid, which is separated into components via centrifugation and stored in blood banks for transfusions.
