Questions and Answers
  • 1. 

    Urutan organ pernapasan yang benar dari luar ke dalam adalah ....

    • A.

      Hidung, tenggorokan, paru-paru

    • B.

      Mulut, tenggorokan, paru-paru

    • C.

      Hidung, kerongkongan, paru-paru

    • D.

      Mulut, kerongkongan, paru-paru

    Correct Answer
    A. Hidung, tenggorokan, paru-paru
    Explanation
    The correct answer is hidung, tenggorokan, paru-paru. The respiratory system starts with the nose (hidung) where air enters the body. From there, the air travels down the throat (tenggorokan) and into the lungs (paru-paru) where oxygen is exchanged for carbon dioxide. This sequence follows the correct pathway of air flow during respiration.

    Udara yang masuk lewat hidung menjadi bersih karena ....

    • A.

      Udara disaring oleh rambut dan selaput lendir hidung

    • B.

      Udara yang masuk bukan udara busuk

    • C.

      Udara masuk lewat organ yang normal

    • D.

      Udara bereaksi dulu dengan lendir di hidung

    Correct Answer
    A. Udara disaring oleh rambut dan selaput lendir hidung
    Explanation
    The correct answer is "udara disaring oleh rambut dan selaput lendir hidung" because the air that enters through the nose is filtered by the hair and mucus lining in the nose. These act as a barrier to trap dust, pollen, and other particles, preventing them from entering the respiratory system. This filtration process helps to keep the air that reaches the lungs clean and free from harmful substances.

  • 3. 

    Fungsi proses pernapasan bagi tubuh adalah sebagai berikut, kecuali ....

    • A.

      Merawat alat peredaran darah

    • B.

      Memasukkan oksigen

    • C.

      Menghasilkan energi untuk proses oksidasi makanan

    • D.

      Mengeluarkan sisa oksidasi yaitu karbon dioksida

    Correct Answer
    A. Merawat alat peredaran darah
    Explanation
    The process of respiration in the body involves inhaling oxygen, which is then used to produce energy through the oxidation of food. This process also results in the release of carbon dioxide as a waste product. However, the respiratory system does not directly maintain or care for the circulatory system, which is responsible for transporting oxygen and nutrients throughout the body. Therefore, the correct answer is "merawat alat peredaran darah" (care for the circulatory system).

  • 5. 

    Proses inspirasi mengakibatkan ....

    • A.

      Otot diafragma berkontraksi

    • B.

      Tekanan dalam rongga dada bertambah

    • C.

      Otot-otot tulang rusuk melemas

    • D.

      Rongga dada mengecil

    Correct Answer
    A. Otot diafragma berkontraksi
    Explanation
    During the process of inspiration, the diaphragm, which is a dome-shaped muscle located at the base of the lungs, contracts. This contraction causes the diaphragm to flatten and move downward, increasing the volume of the thoracic cavity. As a result, the pressure inside the chest cavity decreases, allowing air to rush into the lungs. Therefore, the correct answer is "otot diafragma berkontraksi" (the diaphragm muscle contracts).

    Rate this question:

  • 6. 

    Jika volume udara tidal 500 mL, udara suplementer (cadangan ekspirasi) 1500 mL, udara komplementer (cadangan inspirasi) 1500 mL, dan udara residu 1500 mL, kapasitas vital paru-parunya adalah ....

    • A.

      3500 mL

    • B.

      3000 mL

    • C.

      4500 mL

    • D.

      5000 mL

    Correct Answer
    A. 3500 mL
    Explanation
    The vital capacity of the lungs is the maximum amount of air a person can exhale after taking the deepest breath possible. It is calculated by adding the tidal volume (volume of air inhaled and exhaled during normal breathing) to the inspiratory reserve volume (additional air that can be inhaled after a normal breath) and the expiratory reserve volume (additional air that can be exhaled after a normal breath). In this case, the tidal volume is given as 500 mL, the inspiratory reserve volume is given as 1500 mL, and the expiratory reserve volume is not given. Since the question asks for the vital capacity, we can assume that the expiratory reserve volume is 1500 mL (as it is mentioned as "air residu" which refers to the residual volume, the amount of air remaining in the lungs after a maximum exhalation). Therefore, the vital capacity would be 500 mL + 1500 mL + 1500 mL = 3500 mL.

  • 7. 

    Jika darah kekurangan hemoglobin maka mengakibatkan ....

    • A.

      Darah akan kekurangan oksigen

    • B.

      Tubuh akan kekurangan darah

    • C.

      Peredaran darah terganggu

    • D.

      Oksigen tidak bisa ditukar dengan karbon dioksida

    Correct Answer
    A. Darah akan kekurangan oksigen
    Explanation
    Kekurangan hemoglobin dalam darah akan mengakibatkan darah akan kekurangan oksigen. Hemoglobin adalah protein yang terdapat dalam sel darah merah yang berfungsi untuk mengikat dan mengangkut oksigen ke seluruh tubuh. Jika hemoglobin kurang, maka oksigen tidak dapat diangkut dengan efektif, menyebabkan kekurangan oksigen dalam darah. Hal ini dapat menyebabkan berbagai masalah kesehatan, seperti kelelahan, sesak napas, pusing, dan bahkan kerusakan organ yang serius jika tidak ditangani dengan tepat.

    • A.

      Katup udara

    • B.

      Membantu pencernaan

    • C.

      Katup penutup rongga hidung

    • D.

      Mengatur suara agar nyaring

    Correct Answer
    A. Katup udara
    Explanation
    The correct answer is "katup udara." The epiglottis is a flap of tissue located at the base of the tongue, which prevents food and liquid from entering the windpipe during swallowing. It acts as a valve, closing off the entrance to the larynx and directing food and liquid towards the esophagus.

  • 9. 

    Organ-organ yang tercantum di bawah ini adalah alat pernapasan, kecuali ....

    • A.

      Kerongkongan

    • B.

      Hidung

    • C.

      Tenggorokan

    • D.

      Paru-paru

    Correct Answer
    A. Kerongkongan
    Explanation
    The correct answer is kerongkongan. The other options, hidung, tenggorokan, and paru-paru, are all respiratory organs involved in the process of breathing. The kerongkongan, or esophagus, is not directly involved in respiration but rather in the digestion process, as it is responsible for transporting food from the mouth to the stomach.

  • 10. 

    Meskipun kamu menghembuskan nafas kuat-kuat, udara di dalam paru-paru masih tetap ada. Volume udara ini disebut ....

    • A.

      Udara residu

    • B.

      Udara komplementer

    • C.

      Kapasitas vital

    • D.

      Kapasitas total

    Correct Answer
    A. Udara residu
    Explanation
    Udara residu refers to the air that remains in the lungs even after forcefully exhaling. This air is not expelled during normal breathing and is necessary to prevent the collapse of the lungs. It is the lowest volume of air that can be in the lungs and is essential for maintaining lung function. Udara komplementer, kapasitas vital, and kapasitas total refer to different measurements of lung capacity and are not relevant to the given context.

    • D.

      Volume udara residu

    Correct Answer
    A. Volume udara komplementer
    Explanation
    When we want to hold our breath underwater, we usually take a deep breath before diving into the water. This extra volume of air that we inhale is called the complementary air volume. It is the additional air that fills our lungs beyond the normal tidal volume. This extra air helps us to have enough oxygen to sustain us while we are underwater.

      Eksositosis

    • D.

      Transpor aktif

    Correct Answer
    A. Difusi
    Explanation
    The correct answer is difusi. Pertukaran gas pada alveolus paru-paru terjadi secara difusi, which means that the gases move from an area of high concentration to an area of low concentration. This process allows oxygen to diffuse from the alveoli into the bloodstream, while carbon dioxide diffuses from the bloodstream into the alveoli to be exhaled.

    • C.

      Kontrol pernapasan

    • D.

      Perbedaan aktivitas

    Correct Answer
    A. Perbedaan tekanan
    Explanation
    The exchange of oxygen and carbon dioxide occurs because of the difference in pressure. When there is a difference in pressure between the lungs and the surrounding tissues, oxygen is drawn into the lungs and carbon dioxide is expelled. This pressure difference allows for the efficient exchange of gases, ensuring that oxygen is taken in by the body and carbon dioxide is removed.

    • C.

      Detak jantung meningkat, laju pernapasan menurun

    • D.

      Detak jantung meningkat, laju pernapasan meningkat

    Correct Answer
    D. Detak jantung meningkat, laju pernapasan meningkat
    Explanation
    After someone exercises, their heart rate and respiratory rate increase. This is because during exercise, the body needs more oxygen to fuel the muscles, so the heart pumps faster to deliver oxygen-rich blood to the muscles, and the respiratory rate increases to take in more oxygen and remove carbon dioxide.

    • D.

      Sistem eksresi

    Correct Answer
    A. Sistem otot
    Explanation
    The respiratory system works in collaboration with the muscular system to control breathing. The muscles involved in breathing, such as the diaphragm and intercostal muscles, contract and relax to change the volume and pressure in the lungs, allowing air to be inhaled and exhaled. This coordination between the respiratory system and the muscular system ensures the proper exchange of oxygen and carbon dioxide in the body.
