Confusing words

Do you know the difference between these three words? 

RECEIPT 

RECIPE 

PRESCRIPTION

Receipt is what you get when you buy an item (ticket de compra, recibo, factura) 

Recipe is the set of instructions that you have to follow to cook something (receta de cocina) 

Prescription is what you get when you go to the doctor and he/she prescribes drugs to you (receta médica) 

The words may be confusing because in Spanish we use the same word for recipe and prescription.
