    A long tube that carries food from the mouth to the stomach is ____________. - ProProfs

    A long tube that carries food from the mouth to the stomach is ____________.

    • Trachea

    • Esophagus

    • Urethra

    • Small intestine

    Correct Answer
    A. Esophagus
    Explanation
    The correct answer is the esophagus. The esophagus is a long tube that carries food from the mouth to the stomach. It is located behind the trachea and in front of the spine. The esophagus uses rhythmic muscle contractions called peristalsis to push the food down into the stomach. The trachea is the tube that carries air to the lungs, the urethra is the tube that carries urine out of the body, and the small intestine is the part of the digestive system where most of the absorption of nutrients takes place.

    Rate this question:

  • 3. 
    The opening at the end of the digestive tract in which solid wastes are eliminated is ___________. - ProProfs

    The opening at the end of the digestive tract in which solid wastes are eliminated is ___________.

    • Anus

    • Mucosa

    • Liver

    • Rectum

    Correct Answer
    A. Anus
    Explanation
    The opening at the end of the digestive tract through which solid wastes are eliminated is called the anus. It is the final part of the gastrointestinal tract and is responsible for the excretion of feces from the body. The anus is a muscular structure that allows for the controlled release of waste materials, preventing them from re-entering the body.

    Rate this question:

  • 4. 
    Which organ stores swallowed food and liquid, mixes up digestive juices with the food and liquid, and sends it to the small intestine?   - ProProfs

    Which organ stores swallowed food and liquid, mixes up digestive juices with the food and liquid, and sends it to the small intestine?  

    • Small intestine

    • Large intestine

    • Stomach

    • Liver

    Correct Answer
    A. Stomach
    Explanation
    The stomach is the organ that stores swallowed food and liquid, mixes it with digestive juices, and sends it to the small intestine. It has muscular walls that contract and relax to churn the food, breaking it down into smaller pieces and mixing it with stomach acid and enzymes. This process helps to further break down the food and begin the process of digestion before it moves on to the small intestine for further absorption and digestion.

    Rate this question:

  • 5. 
    Tiny fingerlike projections in the small intestine are __________.   - ProProfs

    Tiny fingerlike projections in the small intestine are __________.  

    • Villi

    • Anus

    • Rectum

    • Urethra

    Correct Answer
    A. Villi
    Explanation
    Villi are tiny fingerlike projections in the small intestine that increase the surface area for absorption of nutrients. They contain blood vessels and lymphatic vessels that help in the absorption and transport of nutrients into the bloodstream. Villi play a crucial role in the digestion and absorption of food in the small intestine.

    Rate this question:

  • 6. 
    The final portion of the large intestine is __________. - ProProfs

    The final portion of the large intestine is __________.

    • Esophagus

    • Rectum

    • Gallbladder

    • Anus

    Correct Answer
    A. Rectum
    Explanation
    The final portion of the large intestine is the rectum. The rectum serves as a temporary storage site for feces before they are eliminated through the anus. It is located between the sigmoid colon and the anus and is responsible for the voluntary control of defecation.

    Rate this question:

  • 7. 
    Which part of the digestive system removes solid wastes such as feces from the body? - ProProfs

    Which part of the digestive system removes solid wastes such as feces from the body?

    • Large intestine

    • Small intestine

    • Esophagus

    • Liver

    Correct Answer
    A. Large intestine
    Explanation
    The large intestine is responsible for removing solid wastes such as feces from the body. It is the final section of the digestive system and absorbs water and electrolytes from the remaining digested food, forming feces. The feces are then stored in the rectum until they are eliminated from the body through the anus. The small intestine is responsible for absorbing nutrients from the food, while the esophagus is the tube that connects the mouth to the stomach. The liver plays a role in producing bile, which aids in the digestion and absorption of fats.

    Rate this question:

  • 8. 
    Which organ stores the liver's digestive juices until they are needed by the intestines? - ProProfs

    Which organ stores the liver's digestive juices until they are needed by the intestines?

    • Pancreas

    • Gallbladder

    • Villi

    • Large intestine

    Correct Answer
    A. Gallbladder
    Explanation
    The gall bladder stores the liver's digestive juices, called bile until they are needed by the intestines. Bile is produced by the liver and helps in the breakdown and absorption of fats in the small intestine. When food containing fats enters the small intestine, the gallbladder releases bile into the digestive tract to aid in the digestion process.

    Rate this question:

  • 9. 
    The place where digested molecules of food, water, and minerals are absorbed is ___________. - ProProfs

    The place where digested molecules of food, water, and minerals are absorbed is ___________.

    • Small intestine

    • Large intestine

    • Mouth

    • Liver

    Correct Answer
    A. Small intestine
    Explanation
    The small intestine is the place where digested molecules of food, water, and minerals are absorbed. It is responsible for the majority of nutrient absorption in the digestive system. The small intestine has a large surface area due to its numerous folds and projections called villi, which increases the absorption capacity. The absorbed nutrients are then transported to the bloodstream to be distributed throughout the body.

    Rate this question:

  • 10. 
    An organ that produces a bodily juice called bile is ____________. - ProProfs

    An organ that produces a bodily juice called bile is ____________.

    • Liver

    • Pancreas

    • Gallbladder

    • Urethra

    Correct Answer
    A. Liver
    Explanation
    The liver is an organ that produces a bodily juice called bile. Bile is a greenish-yellow fluid that helps in the digestion and absorption of fats. It is produced in the liver and stored in the gallbladder before being released into the small intestine. The liver also performs other important functions such as detoxification, metabolism, and storage of nutrients. The pancreas, on the other hand, produces digestive enzymes and insulin, while the gallbladder stores and releases bile. The urethra is a tube that carries urine from the bladder to the outside of the body.

    Rate this question:

  • 11. 
    Which organ contains tiny glands that produce juices to digest food, found in the mouth, stomach, and small intestine? - ProProfs

    Which organ contains tiny glands that produce juices to digest food, found in the mouth, stomach, and small intestine?

    • Villi

    • Mucosa

    • Anus

    • Stomach

    Correct Answer
    A. Mucosa
    Explanation
    The mucosa is the innermost layer of the digestive tract, and it contains tiny glands that produce juices to digest food. These juices contain enzymes that break down food molecules into smaller components that can be absorbed into the bloodstream. The mucosa is found in various parts of the digestive system, including the mouth, stomach, and small intestine, where it plays a crucial role in the digestion and absorption of nutrients.

    Rate this question:

  • 12. 
    The organ that produces a digestive juice that contains a wide array of enzymes to break down fat, carbohydrate, and protein in food is ____________. - ProProfs

    The organ that produces a digestive juice that contains a wide array of enzymes to break down fat, carbohydrate, and protein in food is ____________.

    • Pancreas

    • Liver

    • Large intestine

    • Small intestine

    Correct Answer
    A. Pancreas
    Explanation
    The pancreas is an organ that produces a digestive juice called pancreatic juice. This juice contains a wide array of enzymes, such as lipase, amylase, and protease, which are responsible for breaking down fat, carbohydrate, and protein in food. These enzymes help in the process of digestion and ensure that the nutrients from the food we eat can be absorbed and utilized by the body.
