Lymphatic system

The adenoid, also known as a pharyngeal tonsil or nasopharyngeal tonsil, is the superior-most of the tonsils.

The glymphatic system (or glymphatic clearance pathway) is a functional waste clearance pathway for the vertebrate central nervous system (CNS).

Bone marrow is the flexible tissue in the interior of bones.

Lymph is the fluid that circulates throughout the lymphatic system.

Lymphatic filariasis, also known as elephantiasis, is a human disease caused by parasitic worms known as filarial worms.

The lymphatic system is part of the circulatory system and a vital part of the immune system, comprising a network of lymphatic vessels that carry a clear fluid called lymph (from Latin, lympha meaning water) directionally towards the heart.

A lymphocyte is one of the subtypes of white blood cell in a vertebrate's immune system.

Macrophages (Greek: big eaters, from Greek μακρος (makros) = large, φαγειν (phagein) = to eat) are a type of white blood cell that engulfs and digests cellular debris, foreign substances, microbes, cancer cells, and anything else that does not have the types of proteins specific of healthy body cells on its surface in a process called phagocytosis.

The spleen (from Greek σπλήν—splḗn) is an organ found in virtually all vertebrates.

The thymus is a specialized primary lymphoid organ of the immune system.

Tonsils are collections of lymphoid tissue facing into the aerodigestive tract.

Endothelium is a type of epithelium that lines the interior surface of blood vessels and lymphatic vessels, forming an interface between circulating blood or lymph in the lumen and the rest of the vessel wall.

A lymph node is an oval- or kidney-shaped organ of the lymphatic system, present widely throughout the body including the armpit and stomach and linked by lymphatic vessels.

In anatomy, lymphatic vessels or lymph vessels are thin walled, valved structures that carry lymph.

Chyle (/kaɪl/; from the Greek word χυλός chylos, "juice") is a milky bodily fluid consisting of lymph and emulsified fats, or free fatty acids (FFAs).

Lymphangitis is an inflammation or an infection of the lymphatic channels that occurs as a result of infection at a site distal to the channel.

Germinal centers or germinal centres (GC) are sites within secondary lymph nodes where mature B lymphocytes proliferate, differentiate, and mutate their antibody genes (through somatic hypermutation), and switch the class of their antibodies (for example from IgM to IgG) during a normal immune response to an infection.

Lymphedema is a condition of localized fluid retention and tissue swelling caused by a compromised lymphatic system, which normally returns interstitial fluid to the thoracic duct, then the bloodstream.

Waldeyer's tonsillar ring (pharyngeal lymphoid ring or Waldeyer's lymphatic ring) is an anatomical term collectively describing the annular arrangement of lymphoid tissue in the pharynx.

Peyer's patches (or aggregated lymphoid nodules, or occasionally PP for brevity) are organized lymphoid nodules, named after the 17th-century Swiss anatomist Johann Conrad Peyer.

Lymphatic disease is a class of disorders which directly affect the components of the lymphatic system.

A lymph duct is a great lymphatic vessel that empties lymph into one of the subclavian veins.

The Solitary lymphatic nodules (or solitary follicles) are structures found in the small intestine and large intestine.

A lacteal is a lymphatic capillary that absorbs dietary fats in the villi of the small intestine.

Lymph sacs are a part of the development of the human lymphatic system, known as lymphangiogenesis.
