| Lymphedema | Anatomy and Physiology | | | 4/3/2013 | | Lymphedema Lymphedema occurs when lymph vessels and nodes become damaged or missing in the lymphatic system. Lymph vessels collect fluid that contain proteins‚ water‚ fats‚ and waste from the cells‚ once collected these fluids become lymph. The lymph vessels carry the lymph to the lymph nodes and the lymph nodes act as a type of filter (Cancer‚ 2013). When the lymph vessels and nodes become damage the lymph fluids cannot

I. Introduction A. Description of the Disease Normal cells grow‚ divide and die in an orderly fashion. In an adult‚ cells in most parts of the body divide only to replace worn-out cells and to repair injuries (Cuevas‚ 2007). However‚ these normal cells may be exposed to agents that cause their transformation to cancer cells. These agents are termed as “carcinogenic”. Another theory of how cancer develops states that the body itself produces abnormal cells. Normally‚ these abnormal cells are

The lymphatic system is not a close system and the movement of the lymph fluid moves with low pressure due to functions such as peristalsis‚ valves‚ and the milking action of skeletal muscles. Lymph fluid only ever travels in one direction. As the lymph fluid moves through the body‚ it collects waste products and toxins and disposes of them through the bladder‚ bowel‚ lungs‚ and skin. The lymphatic system also takes part in returning plasma proteins to the bloodstream. The antibodies which are made
