How Does the Muscular System Work In Conjunction With The Immune System?

The muscles connect the bones of the skeletal system and it is one of their main functions. As the muscles contract they move the bones. However, muscles also have other minor functions which are not that well-known. They help in increasing the body fluids, like blood and lymph. The muscular system also helps to improve the immunity in the body.

The immune system is one of the most complex and diverse systems in the human body. It protects the body from bacterial and viral attacks. It works with the white blood cells, and the organs that produce it. In a book entitled "Anatomy and Physiology," authored by Dr. Gary Thibodeau, it is stated that lymph nodes play a very important role in the immune system. The blood passes through spleen, which is a warehouse of cells. The lymph nodes filter the lymphatic fluid and contain immune cells.

Lymphatic fluid is light yellow in color, is the liquid in our blood. The main consistency for the fluid comes from dissolved sugars and salts. It does not contain proteins or cells required by the body. Lymphatic fluid is formed when the blood vessels leak fluids into the blood stream. The lymphatic nodes filter this fluid. Then it is sent back into the capillaries. The fluid that does not enter into the capillaries is sent back into the lymphatic system.

One of the main problems with blood circulation is the wrong posture that most people sit in. The heart is located at the upper portion of the body. The blood that is returning to the heart has to flow up against gravity. The capillaries create pressure and push the blood upwards. The lymphatic fluid too has to go through the same system of circulation. The muscular system plays a very valuable role in sending these fluids upwards. They squeeze the lymph upwards so that the fluid is shut circulating and the lymphatic system functions efficiently.

Lymphatic flow of fluids is very important for circulation and immune system. It helps the fluid travel through the body. The lymphatic fluid re-enters the blood through the lymphatic nodes and here it is checked for immune cells and possible bacteria or viruses. If lymphatic nodes are not functioning properly, they decrease the immunity of a person, making him / her more susceptible to illnesses. Lymph also plays an important role in circulation because if it did not return the blood, the volume of blood in the body will be affected.
