It is known to be the first and foremost step of digestion as food can’t be swallowed effectively without it being turned into something that is easily consumable. For the jaw to be able to churn the food repeatedly‚ it requires muscles to adduct and abduct as well as give it strength to bite on hard food such as tooth-crackers. Muscles of mastication are known to be the most crucial muscles

The response to drug treatment seen in the elderly is very different to that seen with younger patients. Altered drug response in the elderly is often associated with changes in the body that result in modification to the pharmacokinetics of the drugs in older people. Absorption changes result from Morphological changes to the gastrointestinal mucosa. GI function changes have an effect on enzymatic breakdown‚ dissolution‚ and drug ionization which then leads to alterations in oral drug absorption
