The Digestive System
How does the calcium from the milk you drink or vitamin A from the carrots you eat make their way into your body? Your body’s digestive system performs digestion, the process that breaks down food into usable nourishment to power your body’s functions and actions.
Digestion starts when food is chewed in your mouth. Chewed food is then pushed down through your esophagus and into your stomach. From there, food winds its way through your small and large intestines and out of your body when you go to the bathroom.
Along this course, many organs treat the food with their special digestive “juices” to break down food particles into small components your body can use. This process also separates essential nutrients from unusable food-waste. The nutrients are absorbed into your bloodstream and delivered to all parts of your body, while the unwanted waste is excreted out of your body.
With most digested food making its way into every cell of your body, it’s easy to understand the saying, “You are what you eat!”
