I've heard there is a penalty if I don't enroll in Medicare when I turn 65. If covered under an employer's group health plan, you will have 8 months from the time your coverage ends to enroll in Medicare Part B without penalty. For Medicare Part D, you will have 63 days.
Lymph nodes are small bean-shaped structures that are usually less than 2.5 cm in length. They are widely distributed throughout the body along the lymphatic pathways where they filter the lymph before it is returned to the blood.Lymph nodes are not present in the central nervous system.There are three superficial regions on each side of the body where lymph nodes tend to cluster.ymph nodes are small bean-shaped structures that are usually less than 2.5 cm in length.

Lymph enters vessels known as the subclavian veins, which transport it back to the circulatory system. Afferent vessels transport fluid into the lymph nodes, while efferent vessels carry filtered lymph away from the lymph nodes. White blood cells called lymphocytes are a major part of the lymphatic system.Lymph nodes may become swollen when a person gets sick.fter the lymph has been filtered by the lymph nodes, it passes into the efferent vessels. These lymph vessels come together in large groups sometimes referred to as a lymph trunk. They drain the filtered fluid into one of two lymph ducts, which are very large lymphatic vessels.
