where do veins carry blood to?
the heart
what do veins contain?
one way flaps
what is icf?
intracellular fluid and lymph
what occurs due to icf?
fluid is forced out of capillaries and bathes the cells.
where is all material exchange dissolved in?
the icf
where do excess icf get collected in?
the lymphatic system (vessels)
what happens when icf is collected?
it becomes lymph
what happens to all the lymph made from excess icf?
it is drained back into the large veins near the heart.
what do the major lymphatic systems have?
they have lymph nodes
what do phagocytes do in the lymph nodes of the major lymphatic systems?
they filter bacteria and dead cells from the lymph
how much chambers does the heart have?
4 chambers
how are the chambers of the heart split?
