    Urutan alat respirasi dari luar ke dalam pada manusia adalah...

    • Faring-tenggorokan-bronkiolus-bronkus-alveolus

    • Faring-kerongkongan-bronkus-bronkiolus-alveolus

    • Tenggorokan-faring-bronkiolus-bronkus-alveolus

    • Faring-tenggorokan-bronkus-bronkiolus-alveolus

    • Tenggorokan-bronkus-faring-bronkiolus-alveolus

    Correct Answer
    A. Faring-tenggorokan-bronkus-bronkiolus-alveolus
    Explanation
    The correct answer is "faring-tenggorokan-bronkus-bronkiolus-alveolus". This is the correct sequence of respiratory organs in humans, starting from the outside and moving towards the inside. The air enters through the pharynx (faring), then passes through the larynx (tenggorokan), followed by the bronchi (bronkus), bronchioles (bronkiolus), and finally reaches the alveoli (alveolus) where gas exchange occurs.

    Jumlah udara yang diambil oleh paru-paru dalam satu kali bernapas disebut sebagai...

    • Volume tidal

    • Kapasitas vital paru-paru

    • Kapasitas total

    • Kapasitas tidal

    • Volume total

    Correct Answer
    A. Volume tidal
    Explanation
    The correct answer is "volume tidal." Volume tidal refers to the amount of air that is taken in by the lungs during one normal breath. It is the normal, resting breathing volume and does not include any additional air that can be inhaled or exhaled forcefully. The other options, such as kapasitas vital paru-paru and kapasitas total, refer to different lung capacities that involve more than just the normal breath.

    Seorang perokok memiliki risiko gangguan pada saluran pernafasan berikut ini, kecuali...

    • Emfisema

    • Kanker mulut

    • Bronkhitis

    • Kanker paru-paru

    • Asma

    Correct Answer
    A. Kanker mulut
    Explanation
    The given options list various respiratory disorders that are associated with smoking. Emphysema, bronchitis, lung cancer, and asthma are all known to be linked to smoking. However, oral cancer is not primarily caused by smoking but rather by factors such as tobacco chewing, excessive alcohol consumption, and poor oral hygiene. Therefore, the correct answer is "kanker mulut" (oral cancer).

    Proses masuknya O2 pada pernafasan dada disebabkan otot antar tulang rusuk ...

    • Berkontraksi, tekanan udara rongga dada seimbang

    • Berkontraksi, tekanan udara rongga dada tinggi

    • Relaksasi, tekanan udara rongga dada rendah

    • Relaksasi, tekanan udara rongga dada tinggi

    • Berkontraksi, tekanan udara rongga dada rendah

    Correct Answer
    A. Berkontraksi, tekanan udara rongga dada tinggi
    Explanation
    During inhalation, the muscles between the ribs (intercostal muscles) contract. This contraction causes the ribs to move upwards and outwards, increasing the volume of the chest cavity. As a result, the pressure inside the chest cavity decreases. This decrease in pressure creates a pressure gradient between the outside air and the lungs, causing air to flow into the lungs. Therefore, the correct answer is "berkontraksi, tekanan udara rongga dada tinggi" which means "contract, high pressure in the chest cavity".

    Gejala asidosis pada penderita pneumonia adalah manifestasi dari gangguan proses pengangkutan...

    • Oksigen

    • Karbon monoksida

    • Karbondioksida

    • Karbohidrosa

    • Oksihemoglobin

    Correct Answer
    A. Karbondioksida
    Explanation
    Asidosis adalah kondisi ketika kadar asam dalam tubuh meningkat. Gejala asidosis pada penderita pneumonia adalah manifestasi dari gangguan proses pengangkutan karbondioksida. Pneumonia adalah infeksi pada paru-paru yang dapat mengganggu fungsi normal paru-paru, termasuk proses pengangkutan karbondioksida. Jika proses pengangkutan karbondioksida terganggu, maka karbondioksida akan menumpuk dalam darah dan menyebabkan peningkatan kadar asam dalam tubuh. Oleh karena itu, karbondioksida adalah jawaban yang tepat.

    Mekanisme inspirasi yang benar adalah...

    • Diafragma mendatar, tulang rusuk relaksasi, rongga dada pun membesar

    • Diafragma melengkung, tulang rusuk naik, rongga dada mengecil

    • Diafragma mendatar, tulang rusuk kontraksi, rongga dada membesar

    • Diafragma relaksasi, tulang rusuk relaksasi, rongga dada mengecil

    • Diafragma kontraksi, tulang rusuk kontraksi, rongga dada mengecil

    Correct Answer
    A. Diafragma relaksasi, tulang rusuk relaksasi, rongga dada mengecil
    Explanation
    The correct answer is "diafragma relaksasi, tulang rusuk relaksasi, rongga dada mengecil". This is because during inspiration, the diaphragm, which is a dome-shaped muscle located at the bottom of the ribcage, relaxes and moves upward, while the ribs also relax and move downward. This relaxation of the diaphragm and ribs decreases the volume of the chest cavity, causing the lungs to expand and air to be drawn into the lungs. Therefore, the correct mechanism of inspiration involves the relaxation of the diaphragm and ribs, leading to a decrease in the size of the chest cavity.
