Muscles don't push joints, they only shorten and pull. It is up to both reciprocal muscle groups to work together to move the body. For instance, your biceps shortens and bends your elbow, while the triceps on the other side of the arm shortens and returns the elbow to its original position.
Lymph is a clear whitish/yellowish fluid that contains white blood cells (lymphocytes), proteins, and some red blood cells. The bean-shaped lymph nodes of the lymphatic system are connected by vessels. Lymph nodes are usually present in clusters in the armpits, on either side of the neck, and in the groin. The lymph nodes filter lymph fluid and trap foreign materials.
From Wikipedia, the free encyclopedia. Lymph is the fluid that circulates throughout the lymphatic system. The lymph is formed when the interstitial fluid (the fluid which lies in the interstices of all body tissues) is collected through lymph capillaries.It is then transported through lymph vessels to lymph nodes before emptying ultimately into the right or the left subclavian vein, where it mixes back with blood.ince the lymph is derived from the interstitial fluid, its composition continually changes as the blood and the surrounding cells continually exchange substances with the interstitial fluid. Lymph returns proteins and excess interstitial fluid to the bloodstream.
