The human body is a separate state, where every organ, every tissue and even a cell has its own functions and responsibilities. Nature has made sure that they are carried out as best as possible. Red bone marrow is one of the most important and responsible organs of the human body. It provides the formation of blood.
It should first say what the bone marrow is in general. This is one of the main components of the human body, carrying out blood formation. It includes two main components - red bone marrow and yellow, the latter mostly consists of fat tissues. The yellow type of bone marrow replaces the second with age, thus slowing the formation of blood cells, and also reducing the level of natural defense of the body.
The red bone marrow is represented in appearance as a viscous substance of dark brown color. It is located inside human bones (in different bones, depending on the person's age) and plays a crucial role in the formation of new blood cells, and is also responsible for the strength of human immunity.
In adults, red bone marrow is located in bones of flat type, as well as in each of the vertebrae. It starts to form during intrauterine development of the child. When the fetus is performed a little more than one and a half months, the red bone marrow begins to be laid in the clavicles. At the sixth month of development of the child in the womb, this body already fully performs all its functions, accounting for just over one and a half percent of the child's body weight. In the adult body this ratio increases and is up to six percent of the weight.
There is a large number of related medical disciplines that study red bone marrow - histology (the science of the structure of body tissues), cytology (science, studying cells), anatomy, biology and many others. All these sciences pay attention to the uniqueness of this body: it consists of young or "undeformed" cells, which are responsible for the creation of the three main types of human blood cells (which are leukocytes, platelets and red blood cells). In an adult developed body, the red bone marrow is mainly concentrated in the pelvic bones.
Since the hematopoietic cells have the appearance and properties of "not ready" cells, they are very similar in properties to the cells of malignant tumors (cancerous). That is why in the case of treatment of malignant neoplasms with chemotherapy, significant damage is also caused to the bone marrow cells. The thing is that the chemical elements, in comparison with the usual cells of the body, are more susceptible to forming elements, which are both "enemy" particles of tumors and "friendly" hematopoietic "laborers". This similarity is the reason for the need for bone marrow transplantation in patients with cancer and leukemia. However, all the same, cancers are killed a little more quickly with chemotherapy, so with such treatment, patients always have hope for recovery.
