What is the function of the lymphatic system?
returns leaked fluids to blood
What are the organs involved in lymphatic system?
lymphatic vessels, lymph, and lymph nodes
Collect excess tissue fluid and leaked plasma proteins
lymphatic vessels
Fluid contained in lymphatic vessels
lymph
T or F. Lymphatic system in a two-way system
False. One way, lymph flows only toward the heart
From the capillaries to the heart, list the order of events
Lymphatic capillaries -> collecting lymphatic vessels -> lymphatic trunks -> lymphatic ducts-> venous circulation
Specialized lymphatic capillaries that transport absorbed fat from small intestine to blood
lacteals
Formed by union of largest collecting vessels, empty into lymphatic ducts
lymphatic trunks
R or L lymphatic duct. Lymph from right upper limb and right side of head and thorax
Right
R or L lymphatic duct. Lymph from rest of body
Left
How does lymph transport?
muscular and respiratory pumps, valves, pulsations of nearby arteries, rhythmic contraction of smooth muscles
Localized edema caused by anything that prevents return of lymph to blood
lymphedema
blockage of lymphatic drainage by parasitic worms
Elephantiasis
Three functions of lymphatic vessels
Return excess tissue fluid to bloodstream
Return leaked proteins to blood
Transport absorbed fat from small intestine to blood
