Pada saat terbang, burung bernapas dengan bantuan pundi-pundi udara. Pundi-pundi udara adalah kantung-kantung kecil yang terhubung dengan paru-paru burung dan berfungsi untuk menyimpan udara saat burung terbang. Udara yang disimpan di pundi-pundi udara akan digunakan oleh burung saat terbang jauh atau saat terbang di ketinggian yang tinggi. Hal ini membantu burung untuk mengatur kecepatan dan stabilitas saat terbang.Rate this question:

- A.
Oksigen
- B.
Karbodioksida
- C.
Hidrogen
- D.
Nitrogen
Correct Answer
A. OksigenExplanation
The correct answer is oxygen. Oxygen is the gas that is inhaled by humans and animals during the process of respiration. It is necessary for the cells in our body to produce energy. Oxygen is taken in through the lungs and transported to the cells via the bloodstream.Rate this question:

- A.
Trakea
- B.
Karbodioksida
- C.
Faring
- D.

D. LaringExplanation
The correct answer is "laring" because the question is asking for the term used to refer to the human throat. The laring is the part of the throat that contains the vocal cords and is responsible for producing sound. The trakea is the windpipe, karbodioksida is carbon dioxide, and faring is the pharynx, which is a different part of the throat.Rate this question:

- A.
Perut
- B.
Dada
- C.
Diagfragma
- D.
Alveolus
Correct Answer
C. DiagfragmaExplanation
The correct answer is "diaphragm." The diaphragm is a dome-shaped muscle located below the lungs. During breathing, the diaphragm contracts and flattens, causing the chest cavity to expand and the lungs to fill with air. When the diaphragm relaxes, it returns to its dome shape, causing the chest cavity to decrease in size and the lungs to exhale air. Therefore, the diaphragm plays a crucial role in regulating the expansion and contraction of the lungs during breathing.Rate this question:

- B.
Bronkiolus
- C.

B. BronkiolusExplanation
The correct answer is bronkiolus. Percabangan bronkus refers to the branching of the bronchus, which occurs in the bronchioles. Bronkiolus is the Indonesian term for bronchioles, which are the small air passages in the lungs that branch off from the bronchi. Therefore, bronkiolus is the appropriate term to describe the branching of the bronchus.Rate this question:

- A.
Penyesuaian suhu
- B.
Udara disaring dari debu dan kotoran
- C.
Pertukaran gas
- D.
Penyesuaia kelembapan
Correct Answer
C. Pertukaran gasExplanation
The process that occurs in the respiratory air in the alveoli is the exchange of gases. This refers to the exchange of oxygen and carbon dioxide between the alveoli and the blood vessels surrounding them. Oxygen from the inhaled air diffuses into the bloodstream, while carbon dioxide, a waste product, diffuses from the bloodstream into the alveoli to be exhaled. This exchange of gases is essential for the body to obtain oxygen for cellular respiration and to remove carbon dioxide, a waste product of metabolism.Rate this question:
