Chapter 14: Lymphatic and Immune Systems: Exercises Flashcards
Collection of stationary lymphatic tissue along lymph vessels
lymph node
Large lymphatic vessel that drains lymph from the lower and left side of the body
thoracic duct
Organ in the left upper quadrant of the abdomen that destroys worn-out erythrocytes, activates lymphocytes, and stores blood
spleen
Mass of lymphatic tissue in the nasopharynx
adenoids
Lymphoid organ in the mediastinum that conditions T cells to react to foreign cells in the immune response
thymus gland
Tiniest lymphatic vessels
lymph capillaries
Large lymphatic vessel in the chest that drains lymph from the upper right part of the body
right lymphatic duct
Fluid in the spaces between cells
interstitial fluid
Give the locations of the following lymph nodes:
- inguinal nodes
- axillary nodes
- cervical nodes
- mediastinal nodes
- paraaortic nodes
- mesenteric nodes
Inguinal nodes are located in the groin region.
Axillary nodes are located in the armpit region.
Cervical nodes are located in the neck (of the body) region.
Medistinal nodes are located in the mediastinum .
Paraaortic nodes are located near the aorta in the lumbar region of the body.
Mesenteric nodes are located in the intestinal region.
Lymphocyte that matures from a B lymphocyte and secretes antibodies
plasma cell
Large phagocyte found in lymph nodes and other tissues of the body
macrophage
CD4+ T cell that aids B cells in recognizing antigens
helper T cell
Treg that inhibits the activity of B and T lymphocytes
suppressor T cell
Proteins in the blood that help antibodies and T cells kill their target
complement system
Antigen-presenting cell; shows B cells and T cells what to attack
dendritic cell
