Depressants, like alcohol and benzodiazepines, slow neural activity and can disrupt sleep, memory, and learning. Opiates, such as heroin and morphine, treat pain by acting on endorphin receptors. Both depressants and opiates can be addictive and require careful prescription.

This process involves receiving a bolus of food, churning it, and breaking it down through hydrolysis, resulting in a product called chyme. The stomach's anatomy, including parietal cells, chief cells, and mucus cells, facilitates this complex process.
