What is the process of taking in nutrients after digestion called?

The process of taking in nutrients after digestion is called absorption. During digestion, food is broken down into its constituent nutrients, such as carbohydrates, proteins, fats, vitamins, and minerals. These nutrients are then transferred from the digestive tract into the bloodstream. Absorption primarily occurs in the small intestine, where the walls are lined with villi and microvilli, increasing the surface area to facilitate efficient nutrient uptake.

Once absorbed, these nutrients are transported throughout the body to be used for energy, growth, and repair, playing critical roles in overall health. Understanding the concept of absorption is fundamental to grasping how the body utilizes the food we consume.
