Explanation:
Detailed explanation-1: -White blood cells are made in the bone marrow and protect the body against infection. If an infection develops, white blood cells attack and destroy the bacteria, virus, or other organism causing it. White blood cells are bigger than red blood cells and normally are fewer in number.
Detailed explanation-2: -Red and white blood cells have two main functions: the carriage of oxygen and defence from microbial attack respectively. Together, red cells (erythrocytes) and white cells (leukocytes) are part of the full blood count (FBC), one of the most frequently requested haematology tests.
