Question

Answer

WBC r the police men of our body...they protect us against the foreign microorganisms and provide j us immunity

Answer

(a) WBC (White blood cells) because that fight against germs and protect our body from diseases thus provides immunity.

Answer

Answer:

The correct answer is option 'A' - WBC (White Blood Cells).

White Blood Cells, also known as leukocytes, are a crucial part of the immune system and provide immunity to the body. They play a vital role in defending the body against harmful pathogens such as bacteria, viruses, and fungi.

Functions of White Blood Cells:
1. Phagocytosis: Some types of WBCs, such as neutrophils and macrophages, engulf and destroy harmful microorganisms by a process called phagocytosis. They surround and digest the pathogens, preventing them from causing infections.
2. Production of Antibodies: Lymphocytes, a type of WBC, produce antibodies that recognize and neutralize specific pathogens. These antibodies bind to the antigens present on the surface of the pathogens, marking them for destruction by other immune cells.
3. Immune Surveillance: White Blood Cells constantly patrol the body, monitoring for any signs of infection or abnormal cell growth. They detect and eliminate abnormal cells like cancer cells or cells infected with viruses.
4. Inflammation: Some WBCs release chemical signals, called cytokines, which promote inflammation. Inflammation helps in isolating and eliminating pathogens, as well as initiating the healing process.
5. Memory Response: Memory B cells, a type of lymphocyte, remember specific pathogens that the body has encountered before. This allows for a quicker and more effective immune response upon subsequent exposures to the same pathogen.

Types of White Blood Cells:
There are several types of WBCs, each with its own specific function in the immune system. The main types of WBCs include:
1. Neutrophils: The most abundant type of WBC, neutrophils are the first responders to infection and play a crucial role in phagocytosis.
2. Lymphocytes: Lymphocytes are responsible for producing antibodies and coordinating the immune response. There are two main types of lymphocytes - B cells and T cells.
3. Monocytes: Monocytes are large WBCs that transform into macrophages when they enter tissues. They are responsible for phagocytosis and antigen presentation.
4. Eosinophils: Eosinophils are involved in combating parasitic infections and regulating allergic responses.
5. Basophils: Basophils release chemicals such as histamine during allergic reactions, contributing to inflammation.

In conclusion, White Blood Cells (WBCs) are the part of blood that provides immunity. They perform various functions to protect the body against pathogens and help to maintain overall health and well-being.
