Functions of WBC (white blood cells) in the human body?

WBCs, or white blood cells, lack color and hemoglobin, consisting of a nucleus. Key types include Lymphocytes and Neutrophils, pivotal in defending against infectious diseases. Circulating in blood and lymph fluids, they form a protective barrier against external germs. Normal WBC count is 4000-11,000 cells per microliter, with Neutrophils ranging from 1500-8000 cells. Low counts increase susceptibility to infections.

Lymphocytes, located in spleens and lymph nodes, recognize and combat harmful germs using antibodies, taking weeks for the process. Neutrophils, originating in bone marrow, quickly respond to infections, utilizing phagocytosis to consume and eliminate harmful microorganisms.

White blood cells are crucial for immune system function. Neutrophils prevent entry of harmful germs, while Lymphocytes boost immunity by producing antibodies. Monocytes perform phagocytosis on dead cells, Eosinophils release toxins to combat parasites, and Basophils produce antibodies and anticoagulants.

A low WBC count requires immediate attention, as it may indicate serious infections or other health issues. Causes include medications, infections in bone marrow, inadequate vitamin intake, certain cancers, and fatal diseases. Prioritize a balanced diet rich in nutrients, including vitamins, antioxidants, and fatty acids, through foods like green tea, yogurt, fruits, and vegetables to improve immunity and overall health. Prompt action and maintaining good health are essential for a happy and successful life.
