Microvilli of the small intestine play an important role in digestion by doing which of the following?
Increasing absorptive surface area
Improving blood circulation
Filtering our impurities from the food
Adding microbes to the chyme matter
Peptidase is secreted in which organ?
stomach

Put the following terms in their correct order from the simplest to the most complex. Skin cell, Integumentary system , Epithelial tissue, Stem cell , Skin, Organism
The stomach produces hydrochloric acid which increases the acidity of the stomach to digest the food. However, the small intestine are not damaged by strongly acidic food coming from the stomach. How does our body avoids damaging the small intestine with this strongly acidic food passes out of the stomach?

- How does the digestion and absorption of fat differ from that of carbohydrates? Absorbed fat first enters the lymphatic system, whereas carbohydrates directly enter the blood. Fat absorption occurs in the stomach, whereas carbohydrates are absorbed from the small intestine. Only fat must be worked on by bacteria in the large intestine before it can be absorbed. Carbohydrates need to be emulsified before they can be digested, whereas fats do not. Processing of fat does not require any digestive enzymes, whereas the processing of carbohydrates does.arrow_forwardWhich statement about the large intestine is FALSE? Group of answer choices It is involved with the absorption of sodium. It is involved with the absorption of water. It harbors beneficial bacteria. It secretes digestive enzymes. It is also called the colon.arrow_forwardAt least 70 people attending a national conference became ill with what appeared to be food poisoning. Three hospitals in the area treated and released 48 attendees who complained of nausea and vomiting; others with similar symptoms were hospitalized overnight. A health official noted that all the patients had eaten brunch or lunch at the same hotel. The hotel’s lunch menu included roast chicken, roast beef, and a vegetable pasta dish. Because some of the people who became ill were vegetarian, there was particular interest in determining whether the pasta dish might be contaminated. At the time of the report, health officials were still looking for the source of the outbreak. The hotel was cooperating in the investigation and had voluntarily halted food service for the time being. Explain why you might consider this problem important enough to investigate. Give at least three reasons for investigating and explain suitable recommendations and interventions for controlling the problem…arrow_forward
- Which of the following statements is not true? a. Essential nutrients can be synthesized by the body. b. Vitamins are required in small quantities for bodily function. c. Some amino acids can be synthesized by the body, while others need to be obtained from diet. d. Vitamins come in two categories: fat-soluble and water-soluble.arrow_forwardFigure 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 34.11 Which of the following statements about the digestive system is false? Chyme is a mixture of food and digestive juices that is produced in the stomach. Food enters the large intestine before the small intestine. In the small intestine, chyme mixes with bile, which emulsifies fats. The stomach is separated from the small intestine by the pylloric sphincter.arrow_forward
- Intrinsic factor, found in the lining of the stomach, is needed to? Stimulate the release of bile from the pancreas Absorb vitamin B12 Stimulate the production of digestive enzymes in the liver All of the above.arrow_forwardwhat is responsible for fermenting and digestible carbohydrates and synthesizing B complex vitamins in the large intestine? digestive enzymes, bacterial flora, haustraarrow_forwardThe digestive system processes food into usable and unusable materials. The usable materials are sent to the body's cells as food. What happens to unusable materials? It goes into the pancreas to await disposal. It goes to the right ventricle to await disposal. It goes into the large intestine to await disposal. It goes into the small intestine to await disposal.arrow_forward

A type of lipoprotein that transports lipids from the small intestine to body cells. A byproduct of fat metabolism that results in fatty acids that are then transported to the body cells. A type of cholesterol that transports lipids from the small intestine to body cells. An enzyme from the liver that breaks down triglycerides and transports fatty acids to the body cells.arrow_forward
