Because wbc are called seazer of our body they protect us from all the disease of our body also fight with bad bacteria present in our body upvote the answer

White blood cells, also known as leukocytes, are the blood cells that protect us from infection. Let's explore why white blood cells are responsible for this crucial task.

White Blood Cells: The Body's Defense System
- White blood cells are an essential part of the immune system, which helps protect the body from harmful pathogens such as bacteria, viruses, and other foreign invaders.
- They are produced in the bone marrow and are present in the bloodstream and other tissues throughout the body.
- Unlike red blood cells (erythrocytes) that carry oxygen to the body's tissues, white blood cells primarily function in the immune response.

Types of White Blood Cells
- There are several types of white blood cells, each with its own unique function in defending the body against infection:
1. Neutrophils: These are the most abundant white blood cells and are the first to arrive at the site of infection. They engulf and destroy bacteria and other pathogens.
2. Lymphocytes: These cells play a critical role in the immune response by producing antibodies that target specific pathogens. They also help coordinate and regulate the immune system's overall response.
3. Monocytes: Monocytes are responsible for engulfing and destroying larger pathogens, such as certain types of bacteria and dead or damaged cells.
4. Eosinophils: These white blood cells are involved in combating parasitic infections and help regulate allergic responses.
5. Basophils: Basophils release substances like histamine during allergic reactions and play a role in the body's defense against parasites.

How White Blood Cells Work
- White blood cells are constantly patrolling the body, searching for signs of infection or inflammation.
- When they encounter an invading pathogen, they can recognize it through specific receptors on their surface.
- Once identified, white blood cells can initiate an immune response by releasing chemicals that attract other immune cells to the site of infection.
- They can also engulf and destroy pathogens directly through a process called phagocytosis.
- Additionally, white blood cells can produce antibodies that bind to specific pathogens, marking them for destruction by other components of the immune system.

In conclusion, white blood cells are the blood cells that protect us from infection. They play a crucial role in the immune response by identifying, attacking, and destroying pathogens. Without these essential cells, our bodies would be much more susceptible to infections and diseases.
