,
,• to provide an effective defense
• Lymphocytes, detect problems, and travel to them through the blood stream
• it eliminates local variation in the composition of interstitial fluid by distributing
hormones, nutrients and waste from the tissue of origin and circulates them
Random
• Lymphocytes can pass through capillaries
• The excess fluid from capillaries return to the bloodstream through lymphatic
vessels, which help transport lymphocytes and white blood cells to organs
Lymphatic vessels
• AK lymphatics
• Carry lymph from peripheral tissue to the venous system
• lymph first enters in lymphatic capillaries, and then drains into trunks and
ducky’s (larger major limbs, collecting vessels)
Lymphatic capillaries
• the lymphatic network begins with lymphatic capillaries which branch through
peripheral tissues
• Lined by endothelial cells, but the basement membrane is incomplete or
absent
• Endothelial cells are not found together tightly, but do overlap
• The overlapped area access a one-way valve, it permits, fluids, and solutes to
enter, along with viruses, bacteria and cell debris, but prevent them from
returning back to intercellular space
• They differ from blood capillaries; are closed at one end (blood caps are
continuous tubes), have larger diameters, have thinner walls, typically have
flattened or irregular outline under microscope
• found almost everywhere, except for areas without a blood supply like the
cornea.
