@camel.. lool u aint gonna fail.. just trust n believe that you've done all u cna. freaking out is gonna make u worst.. cheer up ;) hope tat helps

The lymph vessel is there to diffuse all the fatty acids and glycerol..correct??
And my book sucks on the lymphatic system. Apart from what people wrote above..what else do I need to know?
--- End quote ---
The role of the lymphatic system..
1 to drain the tissue fluid back in to the blood
2 to defend the body against disease by producing lymphocytes which relase antibodies to react with antigens (pathogens)
3 to transports lipids, glycerol and fat soluble vitamins, A,D, E and K from the lacteal (lymph capillary) of the villus back into the circulatory system
4 transport water, hormones, glucose, amino acids, minerals and heat in the interstitial fluid (tissue fluid)
5 transport waste products such as CO2, and nitrogenous compounds from the tissue fluid in the lymphatic system
pretty much its like a whole new blood system but only for the tissue fluid.. you might also need to know where the lymphatic system is and etc.. the make up n all but these are the usual questions they ask like wat is the rold of the lymphatic system.. hope tat helps..
and again if anyone finds an error in my post ur welcomed to correct it :)
gud luck!

exactly where is the lymphatic system locatd ???
Thanks in advance
--- End quote ---
lol sorry about that.. its located all around the body.. its a system in itselt.. like there's the blood circulatory system.. the lymphatic system is pretty much similar to the blood circulatory system only its for draining tissue fluid and providing the essential nutrients such as O2 n Glucose to the tissue fluid and draining away all the waste such as C02 n etc.. the lacteals are located in the villus in the small intestines.. but pretty much they are everywhere near the body cells.. just like the blood circulatory system..

k first the kidney recievs the blood from aorta via renal artires....then it goes thru absorbtion n filteration where glucose r all absorbd but excess amino ascids some salts n minerls n some water is left behind in the kidney....the filterd blood is taken bak to teh body via renal vein (vena cava)
then the waste products is sent by the ureter to the bladder where urine is stored....l8r its excretd out thru urethra..
now there r two types of white blood cells phagocyte n lymphocyte
lymphocyte produces anibodies which fites against the bacteria whereas phagocyte engulfs teh bacteria
lymphocyets are produced in the lymphatic system
hope this helps
any coorection regardin these notes r welcomed :)
