Andi menghembuskan napas, kemudian otot diafragma dan otot antar tulang rusuknya mengendur. Akibatnya, rongga dada Andi mengecil dan paru-paru mengempis sehingga CO2 dalam paru-paru terdorong keluar.Berdasarkan peristiwa di atas, yang dialami oleh Andi merupakan peristiwa….
- A.
Inspirasi
- B.
Ekspirasi
- C.
Pertukaran CO2 dan H2O
- D.
Relaksasi
Correct Answer
B. EkspirasiExplanation
Andi mengalami peristiwa ekspirasi. Ketika Andi menghembuskan napas, otot diafragma dan otot antar tulang rusuknya mengendur. Hal ini menyebabkan rongga dada Andi mengecil dan paru-paru mengempis. Akibatnya, CO2 dalam paru-paru terdorong keluar. Ekspirasi adalah proses mengeluarkan udara dari paru-paru melalui pernapasan.Rate this question:

- B.
2
- C.
3
- D.
4
- E.
5
Correct Answer(s)
B. 2
D. 4
E. 5Explanation
The correct answer is 2,4,5. This is because in the given image, the structures labeled as 2, 4, and 5 represent bronchus, diaphragm, and alveoli respectively. The bronchus is the passage that carries air into the lungs, the diaphragm is a muscle that helps in the process of breathing, and the alveoli are small air sacs in the lungs where gas exchange takes place.Rate this question:

Pada saat Rini menghirup udara, otot diafragma mengkerut. Akibatnya, diafragma mendatar, rongga dada Rini membesar dan udara masuk ke paru-paru. Selain itu, paru-paru dapat pula terisi udara dengan mengerutnya otot antar tulang rusuk. Otot antar tulang rusuk yang mengerut menyebabkan rongga dada membesar dan udara masuk ke dalam paru-paru.Peristiwa yang dialami Rini merupakan proses….
- A.
Relaksasi
- B.
Inspirasi
- C.
Ekspirasi
- D.
Kontraksi
Correct Answer
B. InspirasiExplanation
The given passage describes the process of inhaling air. It explains that when Rini inhales, the diaphragm muscle contracts, causing it to flatten and enlarge the chest cavity, allowing air to enter the lungs. Additionally, the intercostal muscles between the ribs also contract, causing the chest cavity to expand and air to enter the lungs. This process is known as inspiration, as it involves the intake of air into the lungs.Rate this question:

Udara yang masuk dan keluar pada paru-paru sebagai alat pernapasan kita bisa disebut udara….
- A.
Pernapasan
- B.
Komplementer
- C.
Tidal
- D.
Residu
Correct Answer
C. TidalExplanation
The correct answer is "Tidal". Tidal refers to the movement of air in and out of the lungs during normal breathing. It is the process of inhaling and exhaling air, allowing for the exchange of oxygen and carbon dioxide in the lungs. This term is commonly used to describe the regular and rhythmic flow of air during respiration.Rate this question:

Volume kapasitas vital paru-paru pada manusia berjumlah ….
- A.
500 mL
- B.
1.500 mL
- C.
2.000 mL
- D.
3.500 mL
Correct Answer
D. 3.500 mLExplanation
The vital capacity of the lungs refers to the maximum amount of air that can be exhaled after a maximum inhalation. In a healthy adult, the average vital capacity is around 4-5 liters, which is equivalent to 4,000-5,000 mL. Therefore, the correct answer of 3,500 mL falls within the typical range of vital capacity for a human.Rate this question:

Seperti sistem-sistem lain yang ada pada tubuh, sistem pernapasan juga bisa mengalami gangguan. Gangguan yang terjadi disebabkan oleh beberapa faktor seperti faktor keturunan, kelainan dan kebiasaan buruk seperti merokok. Berikut beberapa penyakit yang menyerang sistem pernapasan manusia.
- Asma : penyakit yang sering disebut sebagai radang tenggorokan. Hal tersebut disebabkan karena virus atau kuman dan daya tahan tubuh yang lemah
- Flu Burung : penyakit ini disebabkan oleh virus yang sebelumnya telah menjangkiti hewan seperti burung dan mamalia. Virus ini sangat mudah berpindah yaitu melalui medium makanan, minuman, dan sentuhan. Untuk menanggulanginya, makanan yang berhubungan dengan unggas harus dimasak dengan matang karena virus ini akan mati pada suhu yang tinggi.
- TBC : penyakit yang disebabkan karena bakteri Mikrobacterium tuberkulosa. Penyakit ini akan semakin buruk jika banyak bakteri tersebut terkumpul di paru-paru kita, karena bakteri tersebut mampu menyebar melalui pembuluh darah sehingga bisa menyerang organ-organ lain yang vital.
- Faringitis : gangguan pada organ pernapasan terjadi karena penyempitan saluran pernapasan akibat reaksi terhadap suatu rangsang tertentu. Rangsang bisa berupa debu, bulu, asap, udara dingin, serbuk, dan aktivitas berat seperti olahraga.
- A.
1 dan 2
- B.
1 dan 3
- C.
2 dan 3
- D.
3 dan 4
Correct Answer
C. 2 dan 3Explanation
The correct answer is 2 and 3 because both TBC and Faringitis are mentioned as diseases that can affect the respiratory system. TBC is caused by the bacteria Mikrobacterium tuberkulosa and can spread to other vital organs through the bloodstream. Faringitis, on the other hand, is a respiratory disorder caused by the narrowing of the airways due to a reaction to certain stimuli such as dust, smoke, cold air, and strenuous activities. Asma and Flu Burung are not mentioned in relation to the respiratory system in the given information.Rate this question:

Perhatikan gambar di bawah ini, sehingga dapat membantu dalam menjawab soal!Pada saluran pernapasan, ada bagian yang berhubungan dengan saluran pencernaan. Bagian tersebut adalah ….
- A.
Faring
- B.
Laring
- C.
Epiglotis
- D.
Trakea
Correct Answer
C. EpiglotisExplanation
The correct answer is Epiglotis. The question states that there is a part in the respiratory system that is connected to the digestive system. The epiglottis is a flap of tissue located at the base of the tongue that prevents food and drink from entering the windpipe during swallowing, directing them instead to the esophagus and the digestive system. Therefore, the epiglottis is the part that is related to both the respiratory and digestive systems.Rate this question:

Urutan alat pernapasan dari luar ke dalam pada manusia adalah….
- A.
Faring -> Tenggorokan -> Bronkiolus -> Bronkus -> Alveolus
- B.
Kerongkongan -> Tenggorokan -> Bronkus -> Bronkiolus -> Alveolus
- C.
Tenggorokan -> Faring -> Bronkus -> Bronkiolus -> Alveolus
- D.
Faring -> Tenggorokan -> Bronkus -> Bronkiolus -> Alveolus
Correct Answer
B. Kerongkongan -> Tenggorokan -> Bronkus -> Bronkiolus -> AlveolusExplanation
The correct answer is "Kerongkongan -> Tenggorokan -> Bronkus -> Bronkiolus -> Alveolus". This is the correct order of the respiratory organs from outside to inside in humans. The kerongkongan (esophagus) is the tube that connects the mouth to the stomach, followed by the tenggorokan (throat). The bronkus (bronchus) is the main airway that leads into the lungs, followed by the bronkiolus (bronchioles), which are smaller airways within the lungs. Finally, the alveolus (alveoli) are tiny air sacs where gas exchange occurs in the lungs.Rate this question:

CO2 sebagai sisa metabolisme harus dibuang melalui pernapasan. CO2 diangkut menuju ke paru – paru dalam bentuk…
- A.
CO2 bebas
- B.
HbCO2
- C.
Ion karbonat
- D.
CO2 yang terlarut dalam plasma darah
Correct Answer
B. HbCO2Explanation
CO2 is transported in the blood in various forms. One of these forms is HbCO2, which is carbon dioxide bound to hemoglobin. This form of CO2 transport accounts for a small portion of the total CO2 transported in the blood. The majority of CO2 is transported in the form of bicarbonate ions (HCO3-) dissolved in the plasma. Therefore, the correct answer is HbCO2.Rate this question:

Pada penderita pneumonia, alveolus terinfeksi oleh…
- A.
Cairan
- B.
Karbon monoksida
- C.
Karbon dioksida
- D.
Oksihemoglobin
Correct Answer
A. CairanExplanation
Pneumonia is an infection that affects the alveoli, which are tiny air sacs in the lungs responsible for gas exchange. When a person has pneumonia, these alveoli become filled with fluid, such as pus or mucus, instead of air. This fluid makes it difficult for oxygen to reach the bloodstream and for carbon dioxide to be expelled from the body, leading to symptoms like coughing, difficulty breathing, and chest pain. Therefore, the correct answer is "cairan" which means fluid in Indonesian.Rate this question:
