What are the components of the lymphatic system? -
....ANSWER...Lymphatic vessels, lymphatic nodules,
lymphatic organs, and lymphatic cells
What are the functions of the lymphatic system? -
....ANSWER...Return leaked plasma to the blood stream,
screen lymph for foreign substances, house immune

, What is the function of lymphatic ducts? -
....ANSWER...Return the lymph to the cardiovascular

....ANSWER...The right arm, chest, right half of the head
and neck
The thoracic duct drains what areas of the body? -
....ANSWER...Everything else
