Which of the following statements concerning the large intestine is correct?
Group of answer choices
The ileocecal valve is the sphincter between the rectum and the anus
It is responsible for the absorption of most of the water in the gastrointestinal tract
The majority of nutrients are absorbed in the large intestines
The mutualistic bacteria in the large intestine may provide some additional vitamins
The small intestine of the pig has significantly more surface area (through folds and villi) than
that of the frog, and if you were to remove them, the small intestine of the pig is several times
longer than that of the frog. This additional surface area maximizes nutrient absorption by the
pig. Why might the pig need more energy from its food than the frog?

- Figure 34.12 Which of the following statements about the small intestine is false? Absorptive cells that line the small intestine have microvilli, small projections that increase surface area and aid in the absorption of food. The inside of the small intestine has many folds, called villi. Microvilli are lined with blood vessels as well as lymphatic vessels. The inside of the small intestine is called the lumen.arrow_forwardFigure 34.19 Which of the following statements about digestive processes is true?
