Wbc Description And Functions

Neutrophils are a type of white blood cell that play a crucial role in the immune system's response to infection. They are characterized by their irregular widths and segmented nuclei, which are divided into 2-5 lobes. These lobes are always connected by nuclear filaments. Neutrophils are known for their ability to quickly migrate to sites of infection and engulf and destroy pathogens. They are the most abundant type of white blood cell and are essential in the body's defense against bacterial infections.

Lymphocytes are a type of white blood cell that play a crucial role in the immune system. They are responsible for producing antibodies, which are proteins that help to identify and neutralize foreign substances in the body. Lymphocytes also help to develop immunity to infections by remembering previous encounters with pathogens and initiating a rapid immune response upon re-infection. Therefore, lymphocytes are the correct answer as they are directly involved in producing antibodies and developing immunity to infections.

Eosinophils are a type of white blood cell that are characterized by their distinct two-lobed nuclei. This means that their nuclei have two lobes or segments, which is a distinguishing feature of eosinophils. Additionally, eosinophils contain granules that can vary in size, shape, and number within individuals of the same species. Therefore, based on the description provided, eosinophil is the most suitable answer.

Basophils are a type of white blood cell that exhibit chemotaxis, which means they can move towards a chemical signal. They also have limited phagocytic ability, meaning they can engulf and destroy pathogens to some extent. Basophils contain granules that contain histamine, which is involved in allergic reactions, and heparin, which is an anticoagulant. Therefore, basophils are the correct answer to this question.

Neutrophils are a type of white blood cell that play a crucial role in the immune response against fungal and bacterial infections. They are known for their ability to phagocytize (engulf and destroy) these pathogens. Neutrophils are highly mobile and are among the first cells to arrive at the site of infection. They release enzymes and toxic substances to kill the pathogens they engulf, helping to eliminate the infection. Therefore, neutrophils are responsible for the phagocytosis and digestion of fungi and bacteria.

Monocytes are large white blood cells with variably shaped nuclei. They have abundant and vacuolated cytoplasm, which appears blue-gray when stained. This description matches the characteristics mentioned in the question. Neutrophils, eosinophils, and basophils do not have the same features, making monocyte the correct answer.

Eosinophils are a type of white blood cell that are characterized by their light pink, rod-shaped granules. These granules contain enzymes and proteins that help the eosinophils to fight off parasitic infections and modulate allergic responses. Eosinophils are involved in the immune response and can be found in various tissues throughout the body, including the blood, gastrointestinal tract, and respiratory system.

The given description of a nucleus being eccentric, chromatin being coarse and clumped, and the presence of chromocenters in the nucleus suggests that the cell in question is a lymphocyte. Lymphocytes typically have eccentric nuclei, and their chromatin can appear coarse and clumped. The presence of chromocenters, which are dark clumps within the nucleus, is also a characteristic feature of lymphocytes. Therefore, based on the given description, the correct answer is lymphocyte.

Eosinophils are a type of leukocyte that play a role in regulating allergic and acute inflammatory responses. They are capable of inducing tissue damage and also possess some phagocytic ability.

Basophils are a type of white blood cell that are characterized by their pale pink granules with a few dark granules. They are involved in allergic reactions and play a role in the immune response. The description provided matches the characteristics of basophils, making it the correct answer.

Monocytes are a type of white blood cell that play a crucial role in the immune response. They are responsible for defense against intracellular parasites and produce and secrete various substances. Monocytes also perform necrotaxis and necrophagocytosis, which involve moving towards and engulfing dead cells. Additionally, monocytes process antigen information for lymphocytes, helping to activate the adaptive immune response. Therefore, monocytes are involved in multiple immune functions, making them the correct answer in this case.
