Study Notes
Nutrient Absorption
- The small intestine is the primary site for nutrient absorption.
- The majority of carbohydrates, proteins, fats, and vitamins are absorbed in this section.
Structure of Absorption
- The villi and microvilli of the small intestine are the primary structures responsible for nutrient absorption.
- These structures increase the surface area available for the uptake of digested nutrients.
Liver Function in Digestion
- The liver is a crucial organ in digestion, even though it's not directly part of the digestive tract.
- It produces bile, a substance that helps break down fats in the small intestine.
- The liver also plays a role in storing and releasing glucose, detoxifying harmful substances, and synthesizing proteins necessary for digestion.
Functions of the Digestive System
- The digestive system is responsible for breaking down food into usable nutrients, absorbing those nutrients, and eliminating waste products.
- It also plays a role in immune system function and hormone production.
Large Intestine Function
- The large intestine's primary role is to absorb water and electrolytes from the remaining digested food.
- It also forms and stores feces before they are eliminated from the body.
- The large intestine also houses bacteria that play a role in breaking down certain indigestible fibers.
