HOW BLOOD TRANSFUSIONS WORK
Our bodies need blood to deliver oxygen and nutrients and remove waste. How do we receive more when we run dangerously low?
WORDS AILSA HARVEY
When a person loses blood due to injury or illness, preventing the body from functioning effectively, blood from another person may be needed. This is carried out through a blood transfusion.
