Lymphatic System Labeling Quiz

Study Notes

Lymphatic System Components

Cervical lymph nodes: Superficial nodes on the side of the neck that play a crucial role in filtering lymph fluid and supporting immune function.
Tonsils: Lymphatic tissue masses located in the pharynx, essential for trapping pathogens entering through the mouth and nose.
Right lymphatic duct: A vessel that drains lymph from the right upper arm and the right side of the head and thorax into the venous system.
Thymus gland: A mediastinal lymphoid organ responsible for maturing T cells, which are vital for the adaptive immune response.
Axillary lymph nodes: Nodes situated under the armpit that filter lymph from the breast, upper limbs, and parts of the thorax.
Peyer's patches: Aggregations of lymphatic tissue found in the submucosa of the small intestine; they monitor intestinal bacteria and prevent the growth of pathogenic bacteria.
Appendix: A small, blind pouch connected to the cecum, believed to play a role in gut immunity.
Red bone marrow: The site of hematopoiesis where red blood cells, white blood cells, and platelets are produced.
Spleen: An organ that generates lymphocytes, filters blood, stores blood cells, and helps in the destruction of aging blood cells.
Thoracic duct: A major lymph vessel that collects lymph from the left side of the head, neck, chest, abdomen, left arm, and lower limbs, returning it to the bloodstream.
Cistern chyli: An enlarged area on the thoracic duct, serving as a storage site for lymph before it enters the venous system.
Lumbar lymph nodes: Nodes situated in front of the lumbar vertebrae that receive lymph drainage from the gastrointestinal tract and abdominal organs.
Pelvic lymph nodes: Located in the pelvic region, these nodes are responsible for transporting fluid, nutrients, and waste products between tissues and the bloodstream.
Inguinal lymph nodes: Nodes that mainly receive lymph drainage from the lower extremities, crucial in the immune response and fluid balance.
