Question

Patients suffering from anaemia have a lack of ___in their blood.

Answer 1

The main function of haemoglobin in the blood is to carry oxygen from the lungs to the rest of the body. So when there is a lack of haemoglobin in the blood, it means the body is not getting sufficient oxygen. As a result, people suffer from a sense of tiredness and lack of energy. This condition is called anaemia.
