Abstract
White blood cells, also known as leukocytes, are a vital component of the human immune system. They play a critical role in defending the body against infectious diseases, toxins, and foreign invaders. These cells are produced in the bone marrow and circulate throughout the body in the blood and lymphatic systems. There are several types of white blood cells, each with its unique function in the immune system.

Introduction
Accurate and early detection of anomalies in peripheral white blood cells plays a crucial role in the evaluation of well-being in individuals and the diagnosis and prognosis of hematologic diseases. For example, some blood disorders and immune system-related diseases are diagnosed by the differential count of white blood cells, which is one of the common laboratory tests. Data is one of the most important ingredients in the development and testing of many commercial and successful automatic or semi-automatic systems. To this end, this study introduces a free access dataset of normal peripheral white blood cells called Raabin-WBC containing about 40,000 images of white blood cells and color spots. For ensuring the validity of the data, a significant number of cells were labeled by two experts. Also, the ground truths of the nuclei and cytoplasm are extracted for 1145 selected cells. [1].
Types of White Blood Cells
There are five main types of white blood cells, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Neutrophils: Neutrophils are the most abundant type of white blood cells in the body, making up about 60% of the total white blood cell count. They are the first line of defense against bacterial and fungal infections. Neutrophils are phagocytic, meaning they engulf and destroy invading microorganisms. They are also involved in the process of inflammation, which is a critical component of the immune response [2].
Lymphocytes: Lymphocytes are a type of white blood cell that plays a crucial role in the immune system's adaptive response. They are responsible for recognizing and responding to specific pathogens, such as viruses and bacteria. Lymphocytes are divided into two main types: B-cells and T-cells. B-cells produce antibodies, which are proteins that bind to specific pathogens and neutralize them. T-cells, on the other hand, directly attack infected cells and regulate the immune response [3,].
Eosinophils: Eosinophils are a type of white blood cell that is involved in the body's response to allergic reactions and parasitic infections. They release toxic chemicals that kill parasites and play a role in modulating the inflammatory response. Basophils: Basophils are the rarest type of white blood cell, making up less than 1% of the total white blood cell count. They are involved in the body's response to allergic reactions and release histamine, which causes blood vessels to dilate and become leaky, leading to swelling and inflammation [4].
Function of White Blood Cells
White blood cells play a critical role in the body's immune response. When foreign invaders, such as bacteria, viruses, and parasites, enter the body, white blood cells are activated to respond. They work together to recognize, neutralize, and destroy the invading pathogen.The process of recognizing and responding to pathogens involves several steps. The first step is the recognition of the pathogen by the immune system. This is done through the recognition of specific molecules on the surface of the pathogen, called antigens. White blood cells have receptors on their surface that can recognize these antigens and trigger an immune response.Once the pathogen is recognized, white blood cells are activated to respond. This involves several processes, including the production of antibodies, the release of cytokines, and the recruitment of other immune cells to the site of infection. White blood cells also play a critical role in the process of inflammation, which is a critical component of the immune response. Inflammation is a localized response to tissue damage or infection and is characterized by redness, swelling, heat, and pain. The process of inflammation involves the release of inflammatory mediators, such as cytokines, chemokines, and prostaglandins. These mediators attract white blood cells to the site of infection and promote their activation and recruitment. [5,].
Conclusion
All in all, white platelets assume a basic part in the human resistant framework. They are engaged with the acknowledgment and annihilation of microbes, the development of antibodies, and the guideline of the safe reaction. There are a few sorts of white platelets, each with its special capability in the resistant framework. Understanding the job of white platelets in the resistant framework is fundamental for the advancement of new treatments for irresistible and safe intervened sicknesses. A solid white platelet count is basic for keeping up with ideal wellbeing and warding off contaminations and infections.
