Question

Which of the W.B.C. has many lobed nuclei?
A. Monocytes
B. Lymphocytes
C. Neutrophils
D. Basophils

Answer 1

Hint: White blood cells are cells that reside in the blood, lymphatic system, and tissues, also called leukocytes, and are an essential part of the body's defence system. They help protect against infections and also have a part in allergic reactions and inflammation. The number of white blood cells in a sample of your blood is counted by the white blood cell count.

Complete answer:
Monocytes - A type of immune cell formed in the bone marrow that travels to tissues in the body via the blood where it becomes a macrophage or a dendritic cell. Macrophages surround microorganisms and kill them, eat foreign material, remove dead cells and increase immune responses. During inflammation, dendritic cells, by revealing antigens on their surface to other immune system cells, enhance immune responses. A monocyte is both a white blood cell type and a phagocyte type.
Lymphocytes - Lymphocytes are white blood cells that are one of the primary forms of immune cells in the body as well. They are formed and contained in the blood and lymph tissue in the bone marrow. The immune system is a complex network of cells that include lymphocytes, known as immune cells. These cells work together to protect the body against foreign substances that can threaten its function, such as bacteria , viruses, and cancer cells.
Neutrophils - Neutrophils are a white blood cell type. Actually, most of the white blood cells that activate the response of the immune system are neutrophils. The most abundant sort are neutrophils. They are the body's most predominant immune cells which have four lobes in their nucleus.
Basophils- Basophils are a white blood cell type. Even though they are formed in the bone marrow, they are present throughout the body in many tissues. They are part of and play a part in the proper function of the immune system. Basophils include large cytoplasmic granules which, when stained, obscure the cell nucleus under the microscope. The nucleus, however, is noticeable when unstained and it normally has two lobes.

Hence, the correct answer is option (C).

Note: A high count of white blood cells may show that the immune system is working to kill an infection. It can also be a sign of stress, either physical or mental. People with serious blood cancers can also have elevated counts of white blood cells. A low white blood cell count may signal that cells are killed more rapidly than they are produced by an injury or disease, or that too few of them are produced by the body.
