Here’s a completion of your text regarding nutrient absorption in the small intestine with appropriate terminology filled in:
1. The process called **digestion** occurs in the small intestine.
2. Nutrients are absorbed through the lining of the small intestine via a variety of mechanisms. Most nutrients require **facilitated diffusion** where a specific carrier protein is utilized, but no energy is required.
3. Some smaller molecules can cross via **simple diffusion**. Like with facilitated diffusion, no energy is required because the concentration of a nutrient is higher inside the GI tract than in the enterocyte. Unlike with facilitated diffusion, however, no **specific carrier protein** is needed.
4. Nutrients like glucose and amino acids are absorbed through **active transport**, which requires both a carrier protein and energy in the form of ATP.
5. A fourth method is called **endocytosis**, which involves a vesicle that forms from the enterocyte's cell membrane, engulfing the nutrient and then drawing the nutrient into the cell.
6. Once absorbed, water-soluble nutrients like carbohydrates and amino acids enter capillaries and travel to the liver via the **hepatic portal vein**.
7. Fat-soluble nutrients initially travel via the **lymphatic system** before entering the bloodstream.
This provides a comprehensive overview of nutrient absorption mechanisms in the small intestine.
