lymphatic vessels they are the thinner then the veins
lymph movement
muscular activity move lymph through lymphatic vessel
Hydrostatic pressure of tissue fluid drives entry fluid into lymphatic capillaries
edema is a lymph in the interstitial
lymphatic tissue and organs
unencapsulated lymphatic tissue associated with the digestive
malt is a respiratory urinary and reproductive system
lymph nodes are located in groups or chains along the lymphatic vessels
thymus
spleen
Functions of lymph
filter lymph remove bacteria and cellular debris before lymph returned to the blood
immune surveillance monitor body fluids
lymphocytes attack viruses bacteria and parasitic cells that enter a lymph node
Macrophages engulf and destroy foreign particles, debris and damaged cells
thymus
T cell leave the thymus to provide immunity
lobules contain ymphocytes
T lymphocytes leave the thymus to provide immunity
body defenses against inflection
Innate (nonspecific) defenses guard against many types of pathogens respond quickly
pathogens that makes you sick
Adaptive (specific) defenses or immunity respond against only a specific type of pathogen respond more slowly
inflammation a tissue response to injury or infection
innate defense chemical barriers
Acidic environment provided by HCI in gastric juice is lethal to some pathogens
Chemical Barries that kill many pathogens
enzymes is pepsin in the stomach and lysozyme in tears destroy many pathogens
interferons hormone like piptides secreted by lymphocytes and fibroblast
innate defense phagocytesis
Neutrophils engulf smaller particles
phagocytosis engulfment and digestion of pathogens ,foreign particles and debris
Monocytes attack larger ones
