The human body is a separate state where each organ, each tissue and even cell has its own functions and responsibilities. Nature made sure that they were performed as best as possible. Red bone marrow is one of the most important and responsible organs of the human body. It provides blood formation.
It should first be said
what is the bone
marrow of a person in general. This is one of the main components of the human body, carrying out hematopoiesis. It includes two main components - red bone marrow and yellow, the latter for the most part consists of adipose tissue. The yellow type of bone marrow replaces the second with age, thereby slowing down the formation of blood cells, and also reducing the level of natural defense of the body.
Red bone marrow in appearance appears as a viscous substance of a dark brown color. It is located inside human bones (in different bones, depending on the age of the person) and plays a crucial role in the formation of new blood cells, and is also responsible for the strength of human immunity.
In adults, the red bone marrow is located in the bones of the flat type, as well as in each of the vertebrae. It begins to form during the intrauterine development of the child.
When the embryo is performed a little over a month and a half, the red bone marrow begins to be laid in the clavicles. At the sixth month of the baby’s development in the womb, this organ already fully performs all its functions, making up just over one and a half percent of the baby’s body weight. In the adult body, this ratio increases and amounts to six percent of the weight.
There are a large number of related medical disciplines that study red bone marrow - histology (the science of the structure of body tissues), cytology (the science that studies cells), anatomy, biology, and many others. All these sciences draw attention to the uniqueness of this organ: it consists of young or "underformed" cells that are responsible for the creation of the three main types of human blood cells (which are white blood cells, platelets and red blood cells). In an adult developed organism, red bone marrow is mainly concentrated in the bones of the pelvis.
Since hematopoietic cells have the appearance and properties of "unprepared" cells, they are very similar in properties to
cancer cells (cancerous). That is why in the case of treatment of malignant neoplasms with chemotherapy, significant damage is also done to bone marrow cells. The thing is that chemical elements, in comparison with ordinary cells of an organism, are more susceptible to forming elements, which are both "enemy" particles of tumors and "friendly" hematopoietic "hard workers". This similarity is the reason for the need for bone marrow transplantation for patients with cancer and leukemia. However, nevertheless, cancers are killed faster with chemotherapy, therefore, with such treatment, patients always have hope for recovery.
