Is there anything specific we need to focus on? And do you have a good online study guide? thanks 
And By the way, Can you tell me about the Lymph and Lacteal and their functions?
Lymph: the excess of tissue fluid diffuses into the lymphatic system and is now known as lymph fluid
this lymph fluid is carried by the lymph nodes and is poured into the subclavian vein
Lacteal: it is a structure inside a villus which absorbs fatty acids and glycerol
