Step 1
Name a blood product extracted from donated blood and outline how it could be used to restore normal body function.
Answer
One blood product extracted from donated blood is Plasma. Plasma can be used to restore normal body function by providing essential proteins and electrolytes, which help maintain blood volume and pressure. Additionally, plasma transfusions are critical in treating conditions like liver failure, burns, and severe infections, helping to stabilize patients and support their recovery.
Step 2
Propose TWO reasons why research is needed to develop alternatives to donated blood.
Answer
-
Supply Shortages: Research is necessary to find alternatives to ensure an adequate supply of blood components, especially during times of crisis or natural disasters, where demand may exceed available donations.
-
Risk of Transmission: Developing alternatives can minimize the risk of transmitting infections and diseases through blood transfusions, prioritizing patient safety and enhancing treatment outcomes.
