- A Dr. Brad J. Spellberg, MD , Infectious Disease, answered. The thymus is a gland in the neck that is most active during childhood and begins to slowly disappear during teenage years and young adulthood. A small amount of thymus is left during adulthood. The primary function of the thymus is as part of the immune system.

Thymus 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.s the thymus is the organ of T-cell development, any congenital defect in thymic genesis or a defect in thymocyte development can lead to a profound T cell deficiency in primary immunodeficiency disease.

An Overview of the Thymus The thymus is special in that, unlike most organs, it is at its largest in children. Once you reach puberty, the thymus starts to slowly shrink and become replaced by fat. By age 75, the thymus is little more than fatty tissue. Fortunately, the thymus produces all of your T cells by the time you reach puberty.

- Once formed in the thymus, mature T cells migrate to peripheral lymphoid organs to initiate the cell-mediated immune response. Importantly, hormones can control thymus physiology, including T-cell development, and the thymus itself can also affect endocrine axes.

First astronauts to orbit the moon are furious after craters named after them to honor their feat are 'switched' to ones that can't be seen from Earth On their Apollo 8 mission they got the first glimpse of the Earth from the far side of the moon. He also provided the IAU with a map of the Apollo 8 flight path, to show how the craters and landmarks along its orbit were chosen, and he says the agency kept his map and never got it back.

thymus At birth, the thymus weighs 10-15 g; by puberty, it weighs about 20 g. After this, the cortical regions of the thymus shrink and become replaced by adipose tissue, although the thymus continues to produce hormones and some thymocytes into old age.

- The thymus gland is an organ in the upper chest cavity that processes lymphocytes, a type of white blood cell that fights infections in the body. This organ is part of both the lymphatic system, which makes up a major part of the immune system, and the endocrine system, which includes all glands that produce hormones.he thymus gland is most important to children and young adults as it programs white blood cells to attack antigens. Different types of white blood cells programmed within the thymus gland.

- The thymus is located in the chest just above the heart, according to Merck Manual. This small organ stores immature lymphocytes (specialized white blood cells) and prepares them to become active T cells, which help destroy infected or cancerous cells. Tonsils are large clusters of lymphatic cells found in the pharynx.

Thymus The thymus is a lymphoid gland comprised of two identically sized lobes, located behind the sternum (breastbone) but in front of the heart. It derives its name from a resemblance it bears to the bud of the thyme plant (thymus in Latin). At puberty, the thymus reaches the height of its use, becoming its largest.

Normal Structure, Function and Histology of the Thymus The thymus is the first of the lymphoid organs to be formed and grows considerably immediately after birth in response to postnatal antigen stimulation and the demand for large numbers of mature T cells. Genetic factors also influence the age of onset, rate and magnitude of thymus dependant immunological function.

What is the Thymus Gland? The thymus gland is most important to children and young adults as it programs white blood cells to attack antigens. Different types of white blood cells programmed within the thymus gland.Chest pain may indicate a tumor of the thymus gland. The thymus is located just below the throat, behind the sternum.wo irregularly shaped parts make up the thymus, which is located directly just below the throat, behind the sternum. The gland releases a hormone that stimulates the production of a certain type of white blood cell in the bone marrow; these cells, called thymocytes are transported by the bloodstream to the thymus.

Anatomy of the Endocrine System The gland produces thymosins, which are hormones that stimulate the development of antibodies. The thymus also produces T-lymphocytes which are white blood cells that fight infections and destroy abnormal cells. The thymus gland is very active in childhood.

Thymus Gland As the thymus shrinks, its tissues are replaced by adipose tissue. The shrinking is due to the reduced role of the thyroid in adulthood – the immune system produces most of its T cells during childhood and requires very few new T cells after puberty.
