What Does White And Red Blood Cells In Urine Mean

White blood cells (leukocytes), unlike red blood cells, are proliferative and single. There is a high difference for their specific functions, they do not reach the division of cells (mitosis) in the blood, but some prevent the ability of mitosis. As a group they are involved in the body’s defense and recovery processes. The number of white blood cells in normal blood is between 4,500 and 11,000 per cubic millimeter. Changes happen during the day; the lowest values ​​are found during rest and the highest values ​​during exercise. Body pressure may cause the reading to exceed 20,000 per cubic millimeter. Most of the white cells are outside the circulation, and a few of them are in the blood moving from one place to another. As living cells, their survival depends on their continuous production of energy. The chemical pathways used are more complex than red blood cells and are similar to other cells in the body. White cells, which have a nucleus and can produce ribonucleic acid (RNA), can synthesize proteins. It consists of three classes of cells, each unique in terms of structure and function, called granulocytes, monocytes, and lymphocytes.

Granulocytes, mostly white cells, are larger than red cells (about 12-15 μm in diameter). They have a multilobed nucleus and contain a large number of cytoplasmic granules (ie, granules in the cell material outside the nucleus). Granulocytes are important mediators of the inflammatory response. There are three types of granulocytes: neutrophils, eosinophils, and basophils. All types of granulocytes are identified by the color of the granules when the cells are stained with a mixed dye. The granules of the neutrophil are pink, those of the eosinophil are red, and those of the basophil are blue-black. About 50 to 80 percent of white cells are neutrophils, but eosinophils and basophils together do not exceed 3 percent.

Neutrophils are uniform in size and diameter between 12 and 15 μm. The nucleus consists of two to five lobes that are held together by hair-like threads. Neutrophils move in the amoeboid process. They extend long structures called pseudopodium into which their granules flow; this action is followed by the reduction of filaments based in the cytoplasm, which pulls the nucleus and the back of the cell forward. This is how neutrophils go quickly on a surface. The bone marrow of a normal adult produces about 100 billion neutrophils each day. It takes about one week for a mature neutrophil to form from a primary cell in the spleen; however, once in the bloodstream, the adult cells only live for a few hours or maybe a little longer when they reach the tissues. To protect against the rapid destruction of short-term neutrophils (for example, during infections), the bone marrow is holding a large number of those that are available to respond to inflammation or infection. In the body, neutrophils migrate to areas of disease or injury. The force of attraction that determines the direction in which neutrophils will move is called chemotaxis and is caused by substances that are released in areas of tissue. Of the 100 billion neutrophils circulating outside the bone marrow, half are in the arteries and half are in the blood vessels. Of those that are in the blood vessels, half of them are in the fast blood flow, and the other half goes slowly on the walls inside the blood vessel ( soil), are ready to enter the tissues when a chemotactic signal is received from them.

Neutrophils are strongly phagocytic; they engulf bacteria and other microorganisms and particles. Neutrophil granules are microscopic packets of powerful enzymes that can digest many types of cellular material. When a virus is engulfed by a neutrophil, it is enclosed in a vacuole lined by an invaginated membrane. The contents of the vacuole are expelled from the body. As this happens, neutrophil granules are destroyed (degranulation). A metabolic process in the granules produces hydrogen peroxide and a strong body of oxygen (superoxide), which destroys the bacteria inside. Enzymes carry out the final secretion of the invading organism.

Eosinophils, like other granulocytes, are produced in the bone marrow until they are released into the circulation. Although they are similar in size to neutrophils, the eosinophil has large granules, and the chromatin is usually packed in only two undifferentiated lobes. Eosinophils leave the circulation within hours of being released from fat and migrate into tissues (usually the skin, lungs , and stomach) through lymphatic channels. Like neutrophils, eosinophils respond to chemotactic signals given at the site of cell damage. It is active and phagocytic. Eosinophils are involved in the defense against parasites, and they participate in hypersensitivity and inflammatory responses, especially in absorbing their harmful effects.

Basophils are the smallest number of granulocytes, and their large granules almost completely obscure the two-lobed nucleus. Within hours of being released from the bone marrow, basophils migrate from the circulation to the skin (eg, the skin and mucosa), where they synthesize and store histamine, a natural modulator of the inflammatory response. When damaged, basophils release, along with histamine and other substances, leukotrienes, which cause bronchoconstriction during anaphylaxis (a hypersensitivity reaction ). Rapid inflammatory basophils form together with platelets, macrophages, and neutrophils.

Monocytes are large blood cells (about 15-18 μm in diameter), and make up about 7 percent of leukocytes. The nucleus is relatively large and appears to be hollow or folded rather than large. The cytoplasm contains many fine granules, which usually appear to be larger near the cell membrane. Monocytes are activated and phagocytic. They can use antibiotics as well as red cells and other large particles, but they cannot change the work of neutrophils in the removal and destruction of bacteria. Monocytes usually enter the red tissue areas behind the granulocytes. It is often found in areas of infection.

Learn about the human phagocytosis response by looking at pictures of a leukocyte, or white cell (globular structure), using bacteria.

In the bone marrow, granulocytes and monocytes arise naturally under the influence of granulocyte-macrophage colony-stimulating factor. Monocytes leave the bone marrow and circulate in the blood. After a few hours, the monocytes enter the me, where they give rise to macrophages, the food phagocytes that make up the reticuloendothelial system (or the macrophage system). Macrophages occur in almost all tissues of the body. The ones in the liver are called Kupffer cells, those in the skin are Langerhans cells. In addition to their role as scavengers, macrophages play an important role in defense by processing antigens and processing them so that they can be recognized as foreign substances by lymphocytes.

Lymphocytes are about 28-42 percent of white blood cells, and are part of the response to foreign substances in the body. Most lymphocytes are small, only slightly larger than erythrocytes, with a nucleus that occupies most of the cell. Some are larger and have more cytoplasm containing a few granules. Lymphocytes are slow moving, and their routes of migration outside the blood stream are different from those of granulocytes and monocytes. Lymphocytes are found in large numbers in the lymph nodes, spleen, thymus, tonsils, and lymphoid tissue of the gastrointestinal tract. They enter the circulation through the lymphatic channels that flow specifically in the thoracic lymph duct, which has a connection with the venous system. Unlike other blood cells, some lymphocytes can leave and re-enter the circulation, living for about a year or more. The main ways of lymphocytes are redistributed through the spleen or lymph nodes. Lymphocytes leave the blood freely and enter the lymphoid tissue, passing the barriers that prevent the passage of other blood cells. When stimulated by antigen and certain drugs, some lymphocytes are activated and can divide cells (mitosis).

An electronic device detects a T cell (T lymphocyte) from the immune system of a healthy person.

Lymphocytes regulate or participate in the acquisition of immunity to foreign cells and antigens. They are responsible for antibiotic activity against invading organisms, foreign cells such as blood cells, and foreign proteins and other antigens that are not derived from living cells. The two classes of lymphocytes are not distinguished by standard microscopic examination but by the type of immune response they elicit. B lymphocytes (or B cells) are involved in what is called humoral immunity. When encountering a foreign substance (or an antigen), the B lymphocyte separates into a plasma cell, which secretes immunoglobulin (antibody). The second class of lymphocytes, the T lymphocytes (or T cells), is involved in the regulation of the antibody-producing activity of lymphocytes as well as the direct attack of foreign antigens. T lymphocytes participate in what is called cell-mediated
