Have you ever thought about how much saliva we produce? On average, a human makes about 1 to 2 liters of saliva every day! It's not just about keeping our mouths moist; saliva plays a critical role in digestion, helping to break down food before it even reaches the stomach. Plus, it contains antimicrobial agents that help keep our mouths healthy. Ever made the mistake of thinking saliva is just “spit”? While it might seem like just a watery substance, it's a complex fluid containing enzymes like amylase to break down carbohydrates and lysozyme to fight bacteria. So next time you think about saliva, remember it's working hard behind the scenes—more than just a biological necessity, it's essential to our health!
