Which body system has the following components? Lymph, lymphatic vessels, lymphatic tissue, lymphatic organs
What do you call a mixture of interstitial fluid, solutes, bacteria, viruses, cancer cells, cellular debris, macrophages, lipids, hormones, and lymphocytes?
True or false? Lymph nodes are the same on every person.
What are the microscopic vessels that penetrate most tissues of the body, are closed on one end, have overlapping endothelial cells, and have anchoring filaments that hold these endothelial cells onto nearby structures?
CNS, cartilage, cornea, bone, marrow
Which body tissues do NOT have lymphatic capillaries?
What are the specialized lymphatic capillaries in the small intestine?
What is the liquid found in the lacteals?
What are lymphatic vessels are more similar to: arteries or veins?
True or false: most lymphatic vessels don't have names?
Which lymphatic vessels bring lymph to the nodes to be filtered?
Which lymphatic vessels are used as the lymph exits the nodes?
How many tunics do lymphatic vessels have?
What do you call the large lymphatic vessels, that form where collecting vessels converge? They drain into lymphatic ducts...
What kind of lymph vessels are these? Jugular (there are 2), subclavian (2), bronchomediastinal (2), intestinal (1), lumbar (2).
What are the largest lymph vessels?
Right lymphatic, thoracic
Name the 2 lymphatic ducts.
Which lymphatic cells develop from monocytes and do the following: phagocytosis of foreign substances and internalizing and activating other lymphatic cells?
Which lymphatic cells internalize and present antigens to other lymphatic cells in lymph nodes?
Which lymphatic cells are specialized epithelial cells in the thymus that secrete thymic hormones?
Which lymphatic cells are classified as "T" or "B"?
Natural Killer cells
Which lymphatic cells cause 'bad' cells to kill themselves via apoptosis?
Reticular cells (fibroblasts)
Which cells make the fibers needed for strucutre in the lymphatic system?
What is the process of lymphocyte development and maturation whereby the cells become immunocompetent, i.e. they know the difference between you and not you?
Where do all lymphocytes originate?
Where do T-lymphocytes mature?
How long do lymphocytes live?
Red bone marrow
Where to B-lymphocytes and NK cells mature?
True or false: all lymphocytes originate from hemopoietic stem cells, which then can turn into lymphoid stem cells?
What lymph structures number in the 100s and are found in the neck, axillary, thorax, abdomen, groin, and popliteal areas (behind the knee)?
CT capsule, cortex, medulla
What are the three layers of a lymph node?
What two types of vessels connect to the CT capsule of a lymph node?
True or false: lymph only passes through one single lymph node for filtering.
Which part of the lymph node contains follicles (some with germinal centers where there are actively dividing B cells), dendritic cells, and circulating T cells?
What structures extend inward from the lymph node cortex and contain B cells and T cells?
What kind of cells line the medullary sinuses of the lymph nodes?
Which structures have the following functions: to filter antigens from lymph and to initiate immune responses?
True or false: cancer cells rarely metastasize in lymph nodes.
What's the name for clusters of lymphatic cells without a CT capsule?
Where are lymphatic nodules found?
Mucosa associated lymphatic tissue
What does MALT stand for? (MALT is found in the GI tract, respiratory system, genitals, and urinary tract.)
What is the largest lymphatic organ?
Unlike the lymph nodes, the spleen does not monitor lymph for antigens... what does it monitor?
What lymphatic organ does the following: initiating immune response; serving as a reservoir for RBCs and platelets; phagocytizing RBCs, platelets, bacteria, etc.?
True or false: the spleen has its own large artery and vein.
Which pulp of the spleen associated with arterial blood supply? This pulp consists of lymphocytes and macrophages positioned like sleeves along small branches of the splenic artery; this is where blood flows through and is monitored for a potential immune response.
Which pulp of the spleen is associated with venous blood supply? Its sinuses are gorged with concentrated RBCs and lined with macrophages to get rid of old blood cells and some pathogens.
What part of the red pulp of the spleen carries blood to the splenic vein?
True or false? A person can live without their spleen.
What hormone stimulate maturation and differentiation of T-lymphocytes?
What do the nurse cells create to protect the body from immature lymphocytes?
What's the name for cancer of the lymphatic system
What do you call swelling due to an abnormal accumulation of lymph fluid within the tissues?
What injury can be caused by trauma to the abdomen, affecting the lymphatic system?
Right subclavian vein
Where does the right lymphatic duct empty back into the blood circulation?
Where does the thoracic duct empty back into the blood circulation?
