Question

Quizplus · Accepted Answer

Anaemia results from a decrease in the number of erythrocytes, also known as red blood cells. Erythrocytes contain haemoglobin, which helps to transport oxygen from the lungs to the tissues throughout the body. A reduced number of erythrocytes means that there is less haemoglobin available to carry oxygen, resulting in a decreased O₂-carrying capacity of the blood. Leukocytes, lymphocytes, and macrophages are not directly involved in oxygen transport and therefore do not play a role in the development of anaemia.
