Fill in the blanks with appropriate wods.
1. A process called helps to propel first the bolus and then chyme forward through the esophagus, stomach, and small intestine.
2. Nutrients are absorbed through the lining of the small intestine via a variety of mechanisms. Most nutrients require , where a specific carrier protein is utilized, but no energy is required.
3. Some smaller molecules can cross via , 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 is needed.
4. Nutrients like glucose and amino acids are absorbed through , which requires both a carrier protein and energy in the form of ATP.
5. A fourth method is called , 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 .
7. Fat-soluble nutrients initially travel via the before entering the bloodstream.
8. Most water is absorbed in the , and solid waste is then eliminated.
a. Large intestine
b. Peristalsis
c. Passive diffusion
d. Carrier protein
e. Active transport
f. Facilitated diffusion
