Before birth and throughout childhood, the thymus is instrumental in the production and maturation of
T-lymphocytes or T cells
, a specific type of white blood cell that protects the body from certain threats, including viruses and infections.
What kind of white blood cells WBC's does the thymus make?
Lymphocytes begin their life in bone marrow. Some stay in the marrow and develop into B lymphocytes (B cells), others head to the thymus and become
T lymphocytes (T cells)
. These two cell types have different roles: B lymphocytes — they produce antibodies and help alert the T lymphocytes.
What kind of white blood cells are made in the thymus?
The thymus makes white blood cells called
T lymphocytes (also called T cells)
. These are an important part of the body's immune system, which helps us to fight infection.
What kind of cells are in the thymus?
The thymus tissue is distinguishable into an outer zone, the cortex, and an inner zone, the medulla. The organ is composed principally of two types of cells, called, respectively,
lymphocytes (see lymphocyte) and reticular cells
.
Does the thymus produce red or white blood cells?
Thymus Basics
T-lymphocytes, or T-cells, are one
type of white blood cell
. In humans, the thymus is an organ you can think as a ‘boot camp' for baby T-lymphocytes.
Does the thymus produce white blood cells?
The thymus makes white blood cells called
T lymphocytes
(also called T cells). These are an important part of the body's immune system, which helps us to fight infection. The thymus produces all our T cells before we become teenagers.
What matures in the thymus?
The T Cell:
T-cells
mature in the thymus gland or in the lymph nodes. Since the thymus is only 10-15% functional in the adult, the lymph nodes take on greater importance in the maturation process.
What food increases white blood cells?
Foods high in protein, such as lean meats and poultry, are
high in zinc
— a mineral that increases the production of white blood cells and T-cells, which fight infection. Other great sources of zinc are oysters, nuts, fortified cereal, and beans.
What helps build white blood cells?
Vitamin C
is thought to increase the production of white blood cells, which are key to fighting infections. Almost all citrus fruits are high in vitamin C. With such a variety to choose from, it's easy to add a squeeze of this vitamin to any meal.
What happen if white blood cells are high?
A high white blood cell count may indicate that
the immune system is working to destroy an infection
. It may also be a sign of physical or emotional stress. People with particular blood cancers may also have high white blood cells counts.
What is the target organ of thymus?
| Endocrine gland/ source of hormone Hormone Target organ or tissue | Thymus (regresses in adulthood) Thymopoetin T-lymphocyte cells in blood | Pancreas (islet cells) Insulin (from beta cells) Most tissues, notably muscle and liver | Glucagon (from alpha cells) Primarily liver | Intestinal mucosa Gastrin Stomach |

Can you feel your thymus?
You may know when you have activated the thymus gland as you will feel a
little tingling
or a subtle feeling of ‘joy' or ‘happiness. ‘ Another variation is to do three thumps at a time but emphasize the first thump more firmly. For some people it may take a little time before you ‘feel' anything.
Can you make T cells without a thymus?
After puberty the thymus shrinks and T cell production declines; in adult humans, removal of the thymus does not compromise T cell function. Children born without a thymus because
of an inability to form a proper third pharyngeal pouch during
embryogenesis (DiGeorge Syndrome) were found to be deficient in T cells.
Can you live without a thymus?
A person
without a thymus does not produce these T cells
and, therefore, is at great risk for developing infections. By the time humans reach puberty, the thymus has completed most of its role in the body, shrinks in physical size and becomes dormant.
Are red blood cells made in the thymus?
Red blood cells, most white blood cells, and platelets are produced in the bone marrow, the soft fatty tissue inside bone cavities. Two types of white blood cells, T and B cells (lymphocytes), are also produced in the lymph nodes and spleen, and T cells are produced and mature in
the thymus gland
.
What organ removes old or damage blood cells from the blood?
As you've seen, your
spleen
is often on the “front lines” of your body; in fact, your spleen is a busy organ – especially considering its small size. Your spleen's main function is to act as a filter for your blood. It recognizes and removes old, malformed, or damaged red blood cells.
