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.
