• 8. You Produce About 1-1.5 Quarts of Saliva a Day

• Your salivary glands produce around 1 to 1.5 quarts (1 to 1.5 liters) of saliva daily. This fluid helps with digestion, keeps your mouth moist, and protects teeth and gums from bacteria.

9. Your Stomach Gets a New Lining Every Few Days

• The lining of your stomach is constantly being replaced. Your stomach’s lining is designed to protect it from harsh acids used in digestion, and it gets a new layer every 3 to 4 days to prevent damage from those acids.

10. You Can Smell Without Using Your Nose

• Your sense of smell is mostly controlled by the olfactory bulb in your brain, not the nose itself. You can still perceive smells even with a blocked nose, as the brain can pick up scents from mouth breathing and other pathways.

These facts highlight just how complex and fascinating the human body is, with many systems working constantly to keep you alive and healthy!
