COMPOSITION OF THE BLOOD
Bone marrow, which is inside the bones, is composed of hematopoietic cells by fat cells and supporting tissue.
Haematopoietic stem cells reproduce continuously to form new cells. Some of them will turn and other new stem cells, when mature, will become red cells, white cells and platelets.
Red blood cells, erythrocytes or red blood cells are responsible, through a component called hemoglobin, carry oxygen from the lungs to tissues and carbon monoxide in the opposite direction. Red blood cells are produced in bone marrow at a rate of about two million per second. If they fall, there will be an anemic and not get enough oxygen to tissues.
Platelets are fragments of bone marrow cells circulating in the blood and whose primary function is in the coagulation mechanism. If there is not enough platelets to damaged or cause injury to the blood vessels, bleeding may occur because there is no element that seals the wound of the glass.
White blood cells or leukocytes are involved in the body’s defense against any harmful microorganisms, they also act to destroy cancer cells.
White blood cells are formed by three types of cells known as lymphocytes, monocytes and granulocytes.
Immature cells called granulocytes myeloblastic (it is called myelogenous leukemia). Once matured, they differ in three types of cells called neutrophils, eosinophils and basophils, they are distinguished by size and color of their granules. These granules contain enzymes and other substances that are counter to the action of the chemical elements produced by invading microorganisms.
Monocytes protect the body from bacteria. As granulocytes, suffer a maturation process at its inception called monoblastos. Circulating in the blood for 24 hours, after which they pass to the tissues where they become macrophages, to destroy it due to germs.
The lymph tissue is found in various parts of the body such as lymph nodes, spleen, thymus, tonsils, adenoids, and the bone marrow. This tissue is composed of different types of cells, called lymphocytes are the primary and, among other duties, are responsible for defending the human body. There are two types of lymphocytes, B lymphocytes and T lymphocytes
B lymphocytes recognize and bind the bacteria to them. Granulocytes and monocytes can recognize and destroy only the bacteria when the cells are attached to them.
T cells recognize infected cells and destroy the virus with the help of macrophages.
