The thoracic duct and the right lymphatic duct empty lymph into the>>> subclavian veins
The pharyngeal tonsils are located>>> in the posterior wall of
... [Show More] the nasopharynx.
B-lymphocytes are>>> white blood cells that are generated in red bone marrow
What is the major functional differences between primary and secondary lymphatic organs? Include an example each of a primary and secondary organ.>>> Primary lymphatic organs are responsible for the formation and maturation of lymphocytes; this includes red bone marrow and the thymus. Secondary lymphatic structures do not form lymphocytes, but they contain them. This is where the sites of immune response initiation occurs, and includes the spleen, tonsils, lymph nodes, and more.
Discuss two different features of lymph nodes that contribute to its function. Do not just list them but give a brief description of how they assist in function.>>> -arranged in clusters to allow multiple rounds of lymph filtration
-multiple afferent vs. one efferent vessel increases pressure and pushes lymph through node
-arrangement of immune cells: cortex and medulla house various immune cells to monitor lymph (multiple cells count as one feature, answers that list B-cells and T-cells as two separate features will be given half credit)
-cortical sinuses lined with macrophages to phagocytize pathogens
-CT capsule encloses node for housing immune cells/filtering lymph
These are functions of the lymphatic system except:>>> a. removes excess fluid from tissues
b. absorbs fats from the digestive tract
c. defends the body against microorganisms and other foreign substances
d. regulates body temperature

This statement best describes lymph nodes:>>> a. filter lymph

c. contain a network of reticular fibers
d. contain lymphatic sinuses
