Each parent should know about bone marrow and the immune system, preparing for a child’s blood transplant and bone marrow transplant (BMT).


main points

Bone marrow is soft tissue inside the bone that produces blood cells. The bone marrow produces red blood cells, platelets, and white blood cells. Lymphocytes are made in the bone marrow and play an important role in the body’s immune system. It is the spongy tissue inside our bones. All bones in newborns have active bone marrow, which means that they produce new cells. When your child reaches young adulthood, the bone marrow inner the bones of the hands, feet, arms, and legs stops producing new bone marrow cells. In adults, active it is found in the bones of the spine, hip and shoulder, ribs, sternum, and skull. However, the bone marrow inside the spine and hip has the biggest source of bone marrow cells.


what does bone marrow do

It produces blood cells, called red blood cells, blood platelets, and white blood cells. Inside the bone marrow, blood cells establish as young, immature cells called stem cells. When they produce, blood cells do not live in our bodies for a long time. That’s why it keeps producing all three types of blood cells to keep us healthy.


 Oxygen and carbon dioxide attach to the iron in hemoglobin, allowing the blood cells to transport oxygen to the body. Red blood cells get rid of the carbon dioxide that leaves your body through the lungs when you exhale.

Platelets are blood cells that assist to clot blood (stick together) to terminate bleeding in areas of the body that have been cut or wounded. The tiles form a scab that forms on a small piece.



White blood cells function

White blood cells help the body fight infection. There are many different types of white blood cells that include: lymphocytes, neutrophils, and monocytes. These white blood cells fight against attackers with bacteria, viruses or fungi to help destroy the infection. Every cell differs in appearance eosinophils and basophils. These white blood cells response to allergens that can attack our bodies.


 Immune System

Our immune system protects the body against disease. It kills unwanted microorganisms such as bacteria and viruses that can attack our bodies.



How does our immune system fight infection?

When established into the marrow, lymphocytes enter the lymph nodes. Lymphocytes travel between each node via lymphatic channels. Lymphatic channels meet in big channels that empty into the blood vessels. Lymphocytes get into the blood through these channels. There are three main types of lymphocytes that play an important role in B cells in the immune system (B cells).

These cells come from the bone marrow. They form proteins called antibodies that attach to the external of the microorganisms that cause infection. Generally, they have the shape of Y or T. Each type of antibody reacts to different microorganisms, adhering to molecules called antigens that are on the surface of the microorganism.

It is the attaching of the antibody and the antigen that causes B cells to grow and produce more antibodies that fight the infection. T-lymphocytes (T-cells) These cells grow up in the thymus, which is a small organ in the upper chest, just after the sternum (sternum). T cells help B cells to produce antibodies against attacking bacteria, viruses or other microorganisms. In distinction to B cells, T cells absorb and destroy pathogens directly after binding to the antigen on the surface of the microorganism. Natural killer (NK) cells. This is a kind of lymphocyte that directly attacks cells infected with the virus.
