Can you feel your immune system working?
Yes and no. Your immune system is constantly at work, keeping your body temperature regulated and fighting average germs that attack you everyday (including the ones that sneak into your body when you rub your eyes with your hand or when you pick your teeth with a fingernail) and you can't really feel it working then, but you can feel and see the products of its work. For example, puss in a wound is the result of the immune system working to fight bacteria and infection in and around the injury. Also, when you blow your nose during a cold, the thicker, darker mucus that your mom and dad or your doctor says is a good thing is the result of your immune system working hard to get rid of the germs that are getting and keeping you sick. Another sign that your immune system is working is what is called a fever break. A fever break is the result of your body's immune system working extra hard to fight bacteria and because of that hard work, it uses lots of energy, which heats up your body.

Interstitial fluid comes from blood plasma which leaks out of the pores of capillaries. It differs in that the larger molecules mostly proteins and blood cells are too large to fit through the pores, and so the interstitial fluid lacks these.

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...\
