MICROANATOMY

Detailed explanation-1: -A white blood cell, also known as a leukocyte or white corpuscle, is a cellular component of the blood that lacks hemoglobin, has a nucleus, is capable of motility, and defends the body against infection and disease.

Detailed explanation-2: -Monocytes are a type of white blood cells. They are the largest of all leukocytes. Monocyte has bean shaped nucleus and clear cytoplasm. They are part of the innate immune system of vertebrates.

Detailed explanation-3: -All leukocytes have a nucleus that may vary in shape from each other. For instance, neutrophils have an irregular indented nucleus, eosinophils have a bilobed nucleus, and the nucleus in basophils is very small.

Detailed explanation-4: -Leukocytes are part of the body’s immune system. They help the body fight infection and other diseases. Types of leukocytes are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).

Detailed explanation-5: -Lymphocytes are round cells that contain a single, large round nucleus. There are two main classes of cells, the B cells that mature in the bone marrow, and the T cells that mature in the thymus gland. Once activated, the B cells and T cells trigger different types of immune response.
