ANATOMY AND PHYSIOLOGY OF THE LYMPHATIC SYSTEM12

REPORTER: NOVE JOY DELEA

LYMPHATIC SYSTEM Lymphatic Vessels (transport lymph)Lymphoid Tissue and Organs (body defenses and resistance to disease)

FUNCTION: Pick up excess tissue fluid and return in to the blood stream

Lymph fluid = clear waterEdema Accumulation of fluid in the tissues

LYMPHATIC SYSTEM FUNCTIONS:Maintain bodys fluid balanceImmunological defenses

LYMPH VESSELS acts as drains to collect excess fluid & return it to the venous blood just before it returns to the heart.

LYMP TISSUES AND ORGANS

Lymphatic Systemspecialized component of the circulatory system; is made up of:

Lymph Lymphatic VesselsLymph nodesIsolated nodules of lymphatic tissueTonsilsThymusSpleen

LYMPHATIC SYSTEM

LYMPHATICS1 way system

Between tissue cells and blood capillaries Remarkably permeable (endothelial cells forming the wall overlap and act as minivalves)

Proteins, cell debris, bacteria, viruses, cancer)

Which do not normally enter blood vessels can enter lymph vessels
