What are the 6 lymphatic organs?
The bone marrow, spleen, thymus, lymph nodes, and lymphatic veins are all part of this system (a network of thin tubes that carry lymph and white blood cells). The lymphatic system can be broadly classified into: Primary lymphoid organs, which generate special immune system cells known as B or T lymphocytes.
Where are the lymphatic organs?
They are found at various points around the body, including the throat, armpits, chest, abdomen and groin. Generally they are in chains or groups All are imbedded in fatty tissue and lie close to veins and arteries. Lymph nodes have a wide range of functions but are generally associated with body defence.
What are the 7 main parts of the lymphatic system?
Basic Anatomy The major parts of the lymph tissue are located in the bone marrow, spleen, thymus gland, lymph nodes, and the tonsils. The heart, lungs, intestines, liver, and skin also contain lymphatic tissue.

How many lymph organs are there?
There are two primary lymphatic organs: the red bone marrow and the thymus gland.
What are the 5 organs of the lymphatic system?

What are the lymphatic tissue in the body?
lymphoid tissue, cells and organs that make up the lymphatic system, such as white blood cells (leukocytes), bone marrow, and the thymus, spleen, and lymph nodes.
Are tonsils lymphatic organs?
Tonsils are tiny organs located at the back of our throat. They are part of the lymphatic system and play a key role in our overall health. Tonsils were earlier thought to have no function and were considered an obsolete part of the human body. When they get infected, they are usually removed by surgery.

What are 3 lymph organs and what are their functions?
The primary lymphoid organs are the red bone marrow, in which blood and immune cells are produced, and the thymus, where T-lymphocytes mature. The lymph nodes and spleen are the major secondary lymphoid organs; they filter out pathogens and maintain the population of mature lymphocytes.
What are the six lymphatic trunks?
There are four pairs of lymph trunks: jugular lymph trunks, subclavian lymph trunks, bronchomediastinal lymph trunks, and lumbar lymph trunks.

What are the lymph nodes?
They filter lymph. Lymph nodes are rich with macrophages, B cells, and T cells; therefore, the lymph nodes are primed for activating the immune system. Structurally, lymph nodes have a capsule and medullary chords and sinuses that serve to filter lymph fluid.
Which regions of the body have large clusters of lymph nodes?
D. the axillary, brachial, and subclavian regions. B. the cervical, inguinal, and axillary regions. The neck, inguinal area, and armpits have large clusters of lymph nodes to protect major areas of the body. They are located where collecting lymphatic vessels converge to form trunks.
Why are B lymphocytes called B lymphocytes?
The B lymphocytes are named B cells because they mature in the Bursa of Fabricus (a lymphoid organ of birds, where they were first discovered) and the T lymphocytes are named T cells because they mature in the Thymus. This is also where they become immunocompetent.
What is the term for excess fluid that accumulates in the tissues as interstitial fluid?
D. Lymph is excess fluid formed from plasma that accumulates in the tissues as interstitial fluid. Some of the excess fluid that leaks out of capillaries at the arterial end due to bulk flow is not returned to the blood at the venous end and instead becomes lymph.
Where are lymph nodes located?
They are located where collecting lymphatic vessels converge to form trunks.
Where do lymphatic materials enter the venous circulation?
Lymphatic materials from the right side of the body above the diaphragm enter the venous circulation via the right lymphatic duct.
Which organ harbors macrophages that ingest and recycle materials from erythrocytes that have?
The spleen harbors macrophages that ingest and recycle materials from erythrocytes that have aged or become damaged.
What are the lymph nodes?
They filter lymph. Lymph nodes are rich with macrophages, B cells, and T cells; therefore, the lymph nodes are primed for activating the immune system. Structurally, lymph nodes have a capsule and medullary chords and sinuses that serve to filter lymph fluid.
