      Mastication

    • C.

      Absorption

    • D.

      Metabolism

    Correct Answer
    A. Peristalsis
    Explanation
    Peristalsis refers to a series of squeezing actions by the muscles in the gastrointestinal tract that help move food through the tract. This process involves rhythmic contractions and relaxations of the muscles, which push the food forward and facilitate its digestion and absorption. Mastication, on the other hand, is the process of chewing food, absorption refers to the uptake of nutrients by the body, and metabolism refers to the chemical processes that occur in the body to maintain life. Therefore, peristalsis is the most appropriate answer as it specifically describes the squeezing actions in the gastrointestinal tract that aid in food movement.

      Feces

    • B.

      Chyme

    • C.

      Bile

    • D.

      Diarrhea

    Correct Answer
    A. Feces
    Explanation
    Feces is the correct answer because it is a solid waste product that is formed during the process of digestion. After food is broken down in the stomach and nutrients are absorbed in the small intestine, the remaining waste material is formed into solid feces in the large intestine. Feces mainly consist of undigested food, bacteria, and other waste products that are eliminated from the body through the rectum and anus. Therefore, feces is the appropriate answer in this context.

    • C.

      Mastication

    • D.

      Peristalsis

    Correct Answer
    A. Absorption
    Explanation
    The process of absorption refers to the passage of nutrients from the digestive tract into the circulatory system. After digestion and mastication, the nutrients are broken down into smaller molecules that can be absorbed through the walls of the small intestine. These molecules then enter the bloodstream and are transported to various parts of the body where they are utilized for energy and other essential functions. Peristalsis, on the other hand, is the muscular movement that helps propel food through the digestive tract, while digestion involves the breakdown of food into smaller components.

    • C.

      Passage of food from the digestive tract into the circulatory or lymphatic system

    • D.

      Transport of nutrients and oxygen into individual body cells

    Correct Answer
    A. Breakdown of food into simpler substances for the body to use
    Explanation
    The process of digestion involves breaking down food into simpler substances that can be used by the body. This includes the mechanical and chemical breakdown of food in the digestive tract, such as chewing and the action of enzymes, to release nutrients. These nutrients are then absorbed into the bloodstream and transported to individual body cells, where they are used for energy, growth, and repair. The other options, such as the collection of waste products or the passage of food into the circulatory system, do not accurately describe the process of digestion.

    Rate this question:

  • 20.

      Small intestine

    • D.

      Stomach

    Correct Answer
    A. Esophagus
    Explanation
    The esophagus is the correct answer because it is the part of the digestive tract where the least amount of digestion occurs. The primary function of the esophagus is to transport food from the mouth to the stomach using peristalsis, a series of muscle contractions. While some minimal mechanical breakdown of food may occur in the esophagus, no significant chemical digestion or absorption takes place in this part of the digestive system.

      Carbohydrates, lipids, and proteins

    Correct Answer
    C. Proteins only
    Explanation
    Pepsin is an enzyme that is primarily responsible for breaking down proteins in the stomach. It works by breaking the peptide bonds that hold the amino acids together in proteins, resulting in the breakdown of proteins into smaller peptides. Therefore, pepsin acts only on proteins and not on carbohydrates or lipids.

    Rate this question:

  • 24. 

    Which of the following best describes the pathway of food in the digestive process?

    • A.

      Esophagus, stomach, small intestine

    • B.

      Large intestine, stomach, esophagus

    • C.

      Mouth, stomach, esophagus

    • D.

      Stomach, small intestine, esophagus

    Correct Answer
    A. Esophagus, stomach, small intestine
    Explanation
    The correct answer is "Esophagus, stomach, small intestine". This is because the food first enters the esophagus, which is a muscular tube connecting the mouth to the stomach. From the esophagus, the food then moves into the stomach, where it is broken down further by stomach acids and enzymes. Finally, the partially digested food passes into the small intestine, where the majority of nutrient absorption takes place.

  • 25. 

    What are the basic parts into which carbohydrates are broken down during digestion?

    • A.

      Amino acids

    • B.

      Fatty acids

    • C.

      Glycerol

    • D.

      Monosaccharides

    Correct Answer
    A. Amino acids
    Explanation
    Carbohydrates are broken down into monosaccharides during digestion. Monosaccharides are the simplest form of carbohydrates, consisting of a single sugar molecule. Amino acids, on the other hand, are the building blocks of proteins and are not directly involved in the digestion of carbohydrates. Fatty acids and glycerol are the breakdown products of fats, not carbohydrates.

    Rate this question:

  • 26. 

    Which part of the small intestine increases the surface area for absorption?

    • A.

      Cappillaries

    • B.

      Duodenum

    • C.

      Lacteals

    • D.

      Villi

    Correct Answer
    D. Villi
    Explanation
    The villi are finger-like projections that line the inner surface of the small intestine. They greatly increase the surface area available for absorption of nutrients. The increased surface area allows for more efficient absorption of nutrients into the bloodstream. Capillaries and lacteals are both involved in the absorption process, but they do not specifically increase the surface area like the villi do. The duodenum is the first part of the small intestine, but it does not directly contribute to increasing the surface area for absorption.

  • 28. 

    Which of the following is associated with the problem of constipation?

    • A.

      Consuming a low-fiber diet

    • B.

      Drinking too much water

    • C.

      Following regular meal patterns

    • D.

      Getting too much exercise

    Correct Answer
    A. Consuming a low-fiber diet
    Explanation
    Consuming a low-fiber diet is associated with the problem of constipation because fiber adds bulk to the stool, making it easier to pass through the digestive system. When a person consumes a low-fiber diet, their stool becomes harder and more difficult to pass, leading to constipation. Increasing fiber intake can help soften the stool and promote regular bowel movements.

    How do the waste products of cell metabolism leave the body?

    • A.

      Urine through the kidneys

    • B.

      Breath through the lungs

    • C.

      Perspiration through the skin

    • D.

      Feces through the anal sphincter

    Correct Answer(s)
    A. Urine through the kidneys
    B. Breath through the lungs
    C. Perspiration through the skin
    Explanation
    The waste products of cell metabolism leave the body through urine, breath, and perspiration. The kidneys filter waste from the blood, producing urine which is then excreted. The lungs remove carbon dioxide, a waste product of cellular respiration, through exhalation. Perspiration, or sweat, is another way for the body to eliminate waste products by excreting them through the skin. Feces, on the other hand, is not a waste product of cell metabolism but rather the remains of undigested food that is eliminated through the anal sphincter.

    The production of milk by a mother's body following the birth of a baby.

    • A.

      Lactation

    • B.

      Prolactin

    • C.

      Oxytocin

    • D.

      Letdown Reflex

    Correct Answer
    A. Lactation
    Explanation
    Lactation refers to the production of milk by a mother's body following the birth of a baby. This process is triggered by hormones such as prolactin and oxytocin. Prolactin stimulates the mammary glands to produce milk, while oxytocin helps in the release of milk from the breasts during breastfeeding. The letdown reflex is the process by which the milk is released from the breasts in response to the baby's suckling. Therefore, lactation is the most appropriate term to describe the production of milk by a mother's body after giving birth.

    Correct Answer
    B. Prolactin
    Explanation
    Prolactin is a hormone released from the anterior pituitary gland that stimulates milk production after childbirth. This hormone plays a crucial role in lactation by stimulating the mammary glands to produce milk. Oxytocin, on the other hand, is responsible for milk letdown and contraction of the smooth muscles in the breast. Casein is a type of protein found in milk, and colostrum is the first milk produced after childbirth, rich in antibodies and nutrients. However, neither casein nor colostrum directly stimulate milk production.
