immunity. :D

lymphatic system. hmm. it is a system, along with the immune system, that helps the body to be immune and protect from various diseases, viruses and bacteria. well. there are two kinds of immunity: innate and adaptive. innate is the first line defense, but it couldn't remember what it had attacked before so it might attack our own healthy cells. :) adaptive, on the other hand, take care of the viruses and bacteria if innate haven't killed them. they remember what they had previously attacked, so they are capable of knowing what to do about those viruses they have experienced. well, there is a substance called lymph fluid that looks blood for me and goes around the body. it goes this way: blood to tissue to lymphatic capillaries to lymphatic vessels to lymph nodes to lymphatic vessels to lymphatic trunks to collecting ducts to subclavian veins and circulates again. and wait, there's more. :) there are some components that helps immunizing the body. they are barriers, cells, inflammation and fever. i want to focus more on cells because of the white blood cells. there are different kinds of white blood cells. wait. let's divide WBCs. it can be like this:

WBC - polymorphonuclear granulocyte - neutrophils

basophils

mast cells

eosinophils

WBC - agranulocyte - monocytes - macrophages

dendritic cells

WBC - agranulocyte - lymphocytes - natural killer cells

T lymphocytes

B lymphocytes

if i were the teacher, i would give some interactive and educational clips and games so that it would be nice to be done not only for the students, but also for the teacher so that it will not be BORING. :)
