White blood cells, or leukocytes, are cells of the immune system involved in defending the body against both infectious disease and foreign materials. Five different and diverse types of leukocytes exist, but they are all produced and derived from a multipotent cell in the bone marrow known as a hematopoietic stem cell. They live for about three to four days in the average human body. Leukocytes are found throughout the body, including the blood and lymphatic system.

What are the blood corpuscles that help to build up resistance against...
Blood corpuscles, also known as blood cells, play a crucial role in the body's immune response against diseases. Among these, leucocytes, specifically the white blood cells, are primarily responsible for building up resistance against diseases.
White blood cells, or leucocytes, are a diverse group of cells that work together to protect the body from foreign invaders such as bacteria, viruses, and other pathogens. There are different types of white blood cells, each with its own unique functions.
Leucocytes can be divided into two main categories: granulocytes and agranulocytes. Granulocytes include neutrophils, eosinophils, and basophils, while agranulocytes include monocytes and lymphocytes.
Among the different types of white blood cells, leucocytes are the primary cells involved in the immune response against diseases. They work together to identify, neutralize, and destroy foreign substances in the body.
Leucocytes are responsible for several important functions that help build up resistance against diseases:
1. Phagocytosis: Leucocytes, particularly neutrophils and monocytes, are capable of engulfing and destroying pathogens through a process called phagocytosis. They effectively "eat" the foreign particles and break them down, preventing further infection.
2. Production of antibodies: Lymphocytes, a type of white blood cell, play a crucial role in the production of antibodies. These antibodies are proteins that specifically target and neutralize pathogens, preventing them from causing harm to the body.
3. Immune system regulation: Leucocytes, particularly lymphocytes, help regulate the immune response. They coordinate the actions of other immune cells, ensuring an appropriate and effective response against diseases.
4. Memory response: Lymphocytes also have a unique ability to remember previous infections. This memory response allows the immune system to mount a faster and more effective defense if the same pathogen is encountered again in the future.
In conclusion, leucocytes, particularly white blood cells, are the blood corpuscles that play a vital role in building up resistance against diseases. Through processes such as phagocytosis, antibody production, immune system regulation, and memory response, these cells work together to protect the body from foreign invaders.
