A white blood corpuscle, also known as a white blood cell or leukocyte, refers to a type of cell present in the blood that plays a vital role in the body's immune system. These cells are colorless and translucent, which differentiates them from the red blood cells that primarily carry oxygen. White blood corpuscles can be found in large numbers in the blood, lymphatic system, and tissues throughout the body.
White blood cells are crucial in defending the body against infections, foreign substances, and abnormal cells such as cancerous cells. They work by recognizing and destroying pathogens, producing antibodies, and activating other immune cells. There are different types of white blood corpuscles, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with its distinct functions and characteristics.
The main function of white blood cells is to defend the body against harmful microorganisms, toxins, and foreign particles. When an infection or invasion occurs, the number of white blood corpuscles increases due to the demand for defense mechanisms. This increase is often observed in laboratory blood tests as an elevated white blood cell count, indicating an active immune response.
Additionally, white blood corpuscles play a role in tissue repair and regulating immune responses, ensuring a balance between protection and avoiding self-damage. Understanding the characteristics and functions of white blood corpuscles is essential in diagnosing and treating various diseases related to the immune system.
