3. Lymphatic Vessels
 In anatomy, lymphatic vessels (or lymph vessels or lymphatics) are thin-walled,
valved structures that carry lymph. As part of the lymphatic system, lymph vessels
are complementary to the cardiovascular system. ... These vessels drain into the
right and left subclavian veins respectively.

4. Lymph Nodes
 The primary function of lymph nodes are the filtering of lymph to identify and
fight infection. In order to do this, lymph nodes contain lymphocytes, a type of
white blood cell, which includes B cells and T cells. These circulate through the
bloodstream and enter and reside in lymph nodes.[11] B cells produce antibodies.
Each antibody has a single predetermined target, an antigen, that it can bind to.
These circulate throughout the bloodstream and if they find this target, the
antibodies bind to it and stimulate an immune response.

5. Immunity
 Immunity is the body’s ability to defend itself againgst pathogens,such as bacteria,
viruses, fungi, protozoan, toxins and cancerous tumors Immunity come in two
forms: Natural Immunity and Acquired Immunity

6. Thymus Gland
 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. The
thymus gland, located behind your sternum and between your lungs, is only
active until puberty. After puberty, the thymus starts to slowly shrink and
become replaced by fat. Thymosin is the hormone of the thymus, and it
stimulates the development of disease-fighting T cells.
