      Liver

    • E.

      Kidneys

    Correct Answer
    B. Small intestine
    Explanation
    Absorption mainly occurs in the small intestine because it has a large surface area due to the presence of villi and microvilli. These structures increase the absorption capacity by providing a larger surface area for nutrient absorption. Additionally, the small intestine is lined with specialized cells called enterocytes that have microvilli on their surface, further increasing the absorption area. The small intestine also has a rich blood supply, allowing for efficient transport of absorbed nutrients into the bloodstream.

    ________ forms the roof of the mouth

    Correct Answer
    hard palate
    Explanation
    The hard palate forms the roof of the mouth. It is a bony structure made up of the maxilla and palatine bones. The hard palate separates the oral cavity from the nasal cavity and plays a crucial role in speech production and chewing. It provides a rigid surface against which the tongue can push food during the swallowing process. The hard palate also helps to resonate sound during speech by directing airflow through the oral cavity.

    ___________is the common passageway for food and air

    Correct Answer
    pharynx
    Explanation
    The pharynx is the common passageway for food and air. It is a muscular tube located behind the nasal cavity, mouth, and larynx. When we swallow, the food or liquid passes through the pharynx on its way to the esophagus, while air passes through it on its way to the larynx and then the lungs. The pharynx plays a crucial role in the process of digestion and respiration, making it the correct answer to the question.

    ___________ provides free exchange of air from the pharynx to the middle ear

    Correct Answer
    eustachian tubes
    Explanation
    The eustachian tubes provide a free exchange of air from the pharynx to the middle ear. These tubes are responsible for equalizing the pressure between the middle ear and the atmosphere. When we swallow or yawn, the eustachian tubes open briefly, allowing air to flow in or out of the middle ear. This helps to maintain proper air pressure, preventing discomfort and potential damage to the eardrum.

    Which cells of the pancreas produce the hormone insulin?Which cells of the pancreas produce glucagon?

    Correct Answer
    beta cells, alpha cells
    Explanation
    Beta cells and alpha cells are the cells in the pancreas responsible for producing the hormones insulin and glucagon, respectively. Insulin is produced by beta cells and helps regulate blood sugar levels by facilitating the uptake of glucose into cells. Glucagon, on the other hand, is produced by alpha cells and works in opposition to insulin by increasing blood sugar levels. Together, these two hormones play a crucial role in maintaining the balance of glucose in the body.
