Lab 4 (Chapter 21) Flashcards
What lymph node is located in the armpit?
Axillary
What lymph node is located in the area between the upper thigh and groin?
Inguinal nodes
What lymph node is located in the neck?
Cervical node
What node is located below the sides of the jaw?
Submandibular node
What organ is tucked right behind the kidney?
Spleen
What is located right below the right axillary lymph nodes?
Right lymphatic duct
What could be described as a medial white line that runs down the abdomen?
Thoracic duct
What is the bump on the thoracic duct called?
Cisterna chyli
What is the small worm-looking organ located near the lower right portion of the abdomen?
Appendix
Collecting vessels are what color on most models? What about lymph nodes?
Collecting vessels are usually white, and lymph nodes are typically green or yellow
What are the 4 major functions of the lymphatic system?
1) Drains off excess interstitial fluid, “cleans” it with the lymph nodes, and returns it to blood
2) Returns any leaked plasma proteins back to blood
3) Transports dietary fats
4) Immune responses
Lymph is chemically identical to what type of fluid?
Interstitial fluid (aka tissue fluid)
True or false: there is a one-way flow of lymph until the lymph is returned to the blood
True
What is the order of lymph through the lymphatic system?
1) Lymphatic capillaries
2) Lymphatic collecting vessels
3) Lymphatic trunks
4) Right lymphatic duct OR the thoracic duct
5) Right subclavian vein OR left subclavian vein
The lymphatic trunks originate from what two ducts?
1) Right lymphatic duct
2) Thoracic duct
What does the right lymphatic duct drain?
Drains the upper right side of the body (right head, right neck, right thorax, right arm)
What blood vessel does the right lymphatic duct drain into?
Right subclavian vein
What blood vessel does the thoracic duct drain into?
Left subclavian vein
What does the thoracic duct drain?
The rest of the body (upper left portion of body, abdomen, both legs)
The beginning of the thoracic duct starts where?
In the abdomen
Describe the cisterna chyli
It’s the beginning of the thoracic duct, and is an enlarged sac that several trunks empty into
What is the beginning of the thoracic duct called?
Cisterna chyli
The lymphatic vessels are most similar to what type of blood vessel? Why?
Veins, because they both have:
1) Unidirectional valves
2) Thin walls
What are the two primary lymphoid organs?
1) Red bone marrow
2) Thymus gland
