Step 1
Name TWO products extracted from donated blood, and state their uses.
Answer
-
Plasma: This is the liquid component of blood that carries cells, nutrients, and waste products. Plasma is often used in medical treatments for patients with burns, liver problems, or those undergoing major surgery.
-
Red Blood Cells (RBCs): These cells are responsible for transporting oxygen throughout the body. They are commonly used in transfusions for patients suffering from anemia or during surgeries where significant blood loss occurs.
Step 2
Propose ONE reason why scientists have now begun to develop artificial blood.
Answer
One significant reason scientists are developing artificial blood is the shortage of donated blood. This shortage can impede medical treatments and surgeries, making it critical to have a reliable synthetic alternative.
