... to the following main bodily areas: the circulatory system, central nervous system, fluid balances, motor skills, sexuality, sleep, fat storage, and nutrition. As it travels through the bloodstream, alcohol causes red blood cells to become abnormally large, and decreases the number of white blood cells, which are important for fighting infections. This results in a weakened immune system, placing alcoholics in more ... motor skills for up to days after being consumed.
