Functional Independence measure FIM; a standardized assessment instrument of functional status that is part of the Uniform Data Set for Medical Rehabilitation; it tests 23 items in seven areas of function and uses a seven-point scale for each item.
The major components of the lymphatic system include lymph, lymphatic vessels, and lymphatic organs that contain lymphoid tissues. Lymphatic tissue can also be found in other areas of the body, such as the skin, stomach, and small intestines.
The components of the lymphatic system are divided into two groups â the primary organs and the secondary organs. 1  Primary Organs: The thymus gland and the bone marrow are primary organs. They regulate the production and differentiation of lymphocytes â the cells that make up the immune system. Secondary Organs: The secondary organs include the lymphatic vessels, lymph nodes, aggregated lymphoid tissue, and spleen. These secondary organs are involved, to some extent, in all three lymphatic functions.
