    Whats the difference between an endothelium (capillaries) and epithelium (alveoli)?
    An endothelium is a type of epithelium. It is the inner layer of the tubes that carry blood or lymph so blood vessels and lymph channels.
    An epithelium is a type of connective tissue and is hugely diverse in it's structure and function.

    Do you specifically mean the difference between an epithelium and endothelium? Because that's like saying what is the difference between a vehicle and a Ford Mondeo. All endotheliums are epitheliums but not all epitheliums are endotheliums,

    If you mean the different between the lining of blood vessels and the lining of an alveoli, then that is a different question and I'd start by looking into the cell structure and the cell function and then come ack with what you find.
