3 Vitamins A and D are stored in the liver: xitamins B and G are stored in the liver and in muscle tissue; 



vitamin C is not stored in the body. 



"Human blood normally contains about 5,000,000 red cells per cubic milhmeter. 



SHuman blood normally contains 7000 white cells per cubic millimeter; their proportion is as 1 : 700 

 red cells.
