Leucocytes and Lymphocytes

2. Leucocytes. About 65 per cent of all white cells are leucocytes. Their protoplasm contains granules. Those leucocytes that stain neutral dyes — as the majority do — are called neutrophils. About 1.5 per cent of the total stain with acid dyes and are called eosinophils. And a still smaller number, 0.5 per cent, have granules that stain with basic dyes; these are called basophils. The percentage of oesinophils increases greatly when parasites invade the body.

3. One characteristic of leucocytes is the irregufar, or lobed, appearance of the nucleus. The number of lobes is an index to the cell's age. Ordinarily, about 45 per cent of all leucocytes have a nucleus of three lobes. The life span¹ of a leucocyte is short, from four to twelve days.

З.The function of leucocytes is primarily that of protection against infection. After the skin is pierced and the wound becomes infected, leucocytes from all the body are attracted to this place. Just what

attracts them is not known — the process is called chemotaxis - probably some by-product of bacterial metabolism. When they arrive at the wound, they leave the blood stream. They wage war on the invaders, engulfing the bacteria within their own protoplasm, a process called phagocytosis (literally «cell-eating»). Before the infection is not too overwhelming, the victory usually goes to the leucocytes.
