#lymphatic system
- Adenia — A rare pathological condition or old clinical concept characterized by the congenital absence, severe atrophy, or insufficient development of glands or lymph nodes in a specific region of the body. This structural phenomenon disrupts the normal functioning of the endocrine or immune system, affecting glandular secretion or the body's lymphatic filtration capacity.
- Adenolymphocele — A cystic formation or pathological dilatation of lymphatic vessels localized within a lymph node, occurring as a result of a chronic blockage in lymph circulation. This altered anatomical structure accumulates a clear fluid (lymph) inside the glandular parenchyma, generating a local painless swelling that is visible during high-resolution imaging examinations.
- Adenology — A branch of anatomy and medicine that deals with the macroscopic and microscopic study of glands (endocrine and exocrine) and the lymphatic system, analyzing their structure, positioning, and functions. This structural discipline grounds the understanding of hormonal secretion processes and immune defense mechanisms coordinated by lymph nodes in the human organism.
