What can be the cause of a swolen lymph node under left ear in toddler?

Babies with repeated ear infections, or even colds can have this develop... It's normal, because the lymph system spreads thoughout the body, just like the arteries & veins... the lymph nodes actually grow and get larger when they have to filter out poisons (from infections) that attempt to spread. If you feel in the same area on your body you'll most likely feel small hard knots... this is because after the infections are gone, the lymph glands (nodes) shrink to small "scarred" knots...\

How does the composition of lymph in the cisterna chyli differ from that in the general lymphatic stream?

Composition of the lymph in the cisterna chyli has conduit for the lipid product of digestion.

What are the two major lymphatic vessels of the body?

The major lymphatic duct is the Thoracic Duct which returns lymph from the the whole body except from the right side of the head and the right arm/shoulder. These parts are drained by the Subclavian Trunk. Both vessels drain into the junction of the subclavian and jugular veins on their respective sides. Hope this helps! Aj :) The right lymphatic duct drains lymph from the right upper extremity, head, and thorax. This duct is not present in all. For those with no right lymphatic duct, the lymph trunks drain directly into the veins of the neck

What part of the immune system does not target specific microbial invaders?

Certain types of white blood cells (the "fighter" cells in the immune system) do not have specific microbial targets. Phagocytes engulf a wide range of "foreign" invaders and destroy them. A form of phagocyte, eosinophil, secrete enzymes and destroy a wide range of pathogens. Macrophages also destroy a wide range of microbial invaders rather than having particular targets. Non-phagocytic cells which are non-specific are Basophils and Mast cells, using chemicals to destruct foreign bodies and restricting blood vessels respectively.
