The thoracic duct is much larger and receives lymph from the rest of the body. It collects
lymph from the two large lumbar trunks that drain the lower limbs and from the intestinal
trunk that drains the digestive organs. As the thoracic duct runs superiority, it receives
lymphatic drainage from the left side of the thorax, the left upper limb and the left side of
the head.
Each terminal duct empties its lymph into the venous circulation at the junction of the
internal jugular vein and subclavian vein on its own side of the body.

Two Types of Lymphocytes Produced in Red Bone Marrow
The thymus is found in the inferior neck and extends into the supper ok thorax, where it
partially overlies the heart deep to the sternum.
Location of Thymus
The thymus has important functions primarily during the early years of life. The thymus
is where T lymphocytes become able to defend us against specific pathogens in the
immune response.
Function of Thymus
Prominent in newborns, the thymus continues to increase in size during the first year,
when it is highly active. After puberty, it gradually atrophied and by old age it has been
replaced almost entirely by fibrous and fatty tissue and is difficult to distinguish from
surrounding connective tissue. Even though it atrophies, the thymus continues to
produce immunocompetent cells as we age, although at a declining rate.
Size of Thymus (Adults and Children)
The most important of the secondary lymphoid organs in the body are the lymph nodes,
which cluster along the lymphatic vessels of the body. There are hundreds of these
small organs, but because they are usually embedded in the connective tissue, they are
