Lymph and Associated Diseases

T cells (thymus cells) and B cells are the major cellular components of the adaptive immune response. T cells are involved in cell-mediated immunity, whereas B cells are primarily responsible for humoral immunity The function of T cells and B cells is to recognize specific “non-self” antigens, during a process known as antigen presentation. Once they have identified an invader, the cells generate specific responses that are tailored to maximally eliminate specific pathogens or pathogen-infected cells. The circulatory system, also called the cardiovascular system, is an organ system that permits blood to circulate and transport nutrients, oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis. Lymphatic disease is a class of disorders which directly affect the components of the lymphatic system. The thymus is a specialized primary lymphoid organ of the immune system. Within the thymus, T cells or T lymphocytes mature. T cells are critical to the adaptive immune system, where the body adapts specifically to foreign invaders. The thymus is composed of two identical lobes and is located anatomically in the anterior superior mediastinum, in front of the heart and behind the sternum. Lymphoma is the name applied to a group of blood cell tumors that develop from lymphatic cells. The name often refers to just the cancerous ones rather than all such tumors. Symptoms may include enlarged lymph nodes, fever, drenching sweats, weight loss itching, and feeling tired. The enlarged lymph nodes are usually painless. The sweats are most common at night and all the detail of the lymphatic system and its disorders are seen in the Haematological meetings.
