Leucocyte

Leucocytes, also known as white blood cells, are essential components of your immune system. They help defend your body against infections by identifying and attacking bacteria, viruses, and other harmful substances. There are different types of white blood cells, each with specific roles in immune response. They circulate through your blood and tissues, constantly surveilling for threats. When an infection occurs, white blood cell levels often increase as your body responds more aggressively. Overall, leucocytes are vital for maintaining your health by protecting you from disease and facilitating healing.
