The intestines perform several important functions:
- Digestion: The intestines break down food into smaller pieces.
- Nutrient Absorption: The small intestine takes in vitamins, minerals, and nutrients from food into the blood.
- Water Absorption: The large intestine absorbs water from leftover food, turning it into solid waste.
- Waste Removal: They help get rid of waste by pushing it toward the rectum to be expelled.
- Microbial Balance: The intestines are home to good bacteria that help with digestion and protect against bad germs.
- Immune Function: They help the immune system fight off harmful bacteria and viruses.
