About This Quiz

The study of biology encompasses all aspects of life, whether it’s you and the other people around you in your life, the animals we all know and love from the animal kingdom, the plants that make the world a little greener or the tiny little creatures known as microorganisms we can only see through the use of a microscope. Let’s take a closer look at humans first, shall we? What can you tell us?

    Which of the following organs is not just a digestive organ?

    • Stomach

    • Liver

    • Small intestine

    • Large intestine

    Correct Answer
    A. Liver
    Explanation
    The liver is not just a digestive organ because it has multiple functions in the body. It plays a crucial role in detoxifying harmful substances, producing bile which aids in digestion, storing vitamins and minerals, and regulating blood sugar levels. Additionally, the liver is responsible for metabolizing drugs and producing proteins necessary for blood clotting. Therefore, while the stomach, small intestine, and large intestine primarily function in digestion, the liver has a broader range of functions beyond digestion.

    For food eaten at noon,absortion cannot have begun by?

    • 1 p.m.

    • 7 p.m.

    • 9 p.m.

    • Noon the next day

    Correct Answer
    A. 1 p.m.
    Explanation
    The correct answer is 1 p.m. because absorption of food typically begins within a few hours after eating. Since the food is eaten at noon, it is reasonable to assume that absorption would have started by 1 p.m.

    Rate this question:

  • 4. 

    Which Following parts of the digestive system is best paired with its fuction.

    • Esophagus-digests carborhydrates

    • Stomach-digests fats

    • Small intestine-absorbs water

    • Liver-produces bile

    Correct Answer
    A. Liver-produces bile
    Explanation
    The liver is responsible for producing bile, which is a substance that helps in the digestion and absorption of fats. Bile is stored in the gallbladder and released into the small intestine when needed. The other options mentioned in the question, such as the esophagus, stomach, and small intestine, have different functions in the digestive system but are not specifically responsible for producing bile.

    Rate this question:

  • 5. 

    If a meal is eaten at noon, what happening to the food at 1 p.m.?

    • Salvia is breaking down starch into sugar

    • Proteins are being digested into short chains of amino acids

    • Fats are being digested

    • Digested food is being absorbed into the blood

    Correct Answer
    A. Proteins are being digested into short chains of amino acids
    Explanation
    At 1 p.m., the process of protein digestion is occurring. Proteins are being broken down into shorter chains of amino acids, which are easier for the body to absorb and utilize. This is an important step in the overall process of digestion and nutrient absorption.

    Rate this question:

  • 6. 

    Compare the processes of the mechemical and chemical digestion. How are they similar? How are they different? In what parts of the digestive system do the two processes take place? How do the processes occur?

    • Mechanical digestion causes a physical change as the pieces of food are broken down into smaller pieces.

    • In chemical digestion, foods are broken down chemically into their smaller building blocks with the help of enzymes.

    • The processes are similar in that

    Correct Answer
    A. In chemical digestion, foods are broken down chemically into their smaller building blocks with the help of enzymes.
    Explanation
    In chemical digestion, food is broken down chemically into smaller building blocks with the assistance of enzymes. This process involves the breaking of complex molecules into simpler ones through chemical reactions. On the other hand, mechanical digestion causes a physical change as food is broken down into smaller pieces. This process involves the physical breakdown of food through chewing, grinding, and churning in the stomach. The two processes differ in terms of the type of change they bring about in food. Mechanical digestion involves physical changes, while chemical digestion involves chemical changes. Both processes occur at different parts of the digestive system. Mechanical digestion primarily occurs in the mouth and stomach, while chemical digestion occurs mainly in the small intestine with the assistance of various digestive enzymes.
