Lymph
clear, colorless alkaline fluid made up of mostly water, along with some protein, salts, fats, white blood cells, and urea (a waste product of protein metabolism)
28
Lymphatic vessels
found throughout the body alongside arteries, veins, and capillaries
29
What facilitates lymph flow through lymphatic vessels?
there is no pump like the heart, instead it is facilitated by the pumping action of skeletal muscles
30
lymph nodes
commonly called glands, rich in specialized white blood cells called phagocytes
31
phagocytes
specialized white blood cells, cleans debris from lymph through a process called phagocytosis
32
phagocytosis
A process in which white blood cells engulf and destroy microorganisms, cell debris, and blood cells that are damaged, old, or abnormal
33
lymphatic system
also considered a part of immune system, an intricate network of vessels that collect the excess tissue fluid, called lymph, and return it to the circulation
34
where does lymph enter the circulatory system and combine with blood?
superior vena cava
35
terms for inflamed gland?
lymphadenitis or lymphadenopathy
36
Which areas of the body have especially high numbers of lymph nodes?
neck, axillae (armpits), groin, abdomen
37
Two sets of lymph nodes in the throat
tonsils and adenoids
38
lymphedema
