Soal IPA Kelas 5 Sd (01)

Explanation
Cacing bernafas dengan kulit karena mereka tidak memiliki paru-paru atau sistem pernapasan yang kompleks seperti manusia. Kulit mereka memungkinkan pertukaran gas terjadi secara langsung dengan lingkungan sekitar, memungkinkan oksigen masuk ke dalam tubuh dan karbon dioksida keluar. Ini memungkinkan cacing untuk mendapatkan oksigen yang diperlukan untuk bertahan hidup.

Explanation
Berudu bernafas dengan insang. Insang adalah organ pernapasan pada berudu yang memungkinkan mereka untuk mengambil oksigen dari air. Insang berfungsi seperti paru-paru pada manusia, di mana oksigen diambil dari air melalui insang dan karbon dioksida dikeluarkan. Dengan demikian, insang adalah bagian penting dari sistem pernapasan berudu.

Explanation
Serangga bernafas dengan menggunakan trakea. Trakea adalah sistem pernapasan serangga yang terdiri dari serangkaian tabung kecil yang disebut trakea. Trakea ini berfungsi untuk mengirim udara langsung ke dalam tubuh serangga, memungkinkan pertukaran gas yang efisien. Dengan menggunakan trakea, serangga dapat mengambil oksigen dari udara dan membuang karbon dioksida, sehingga memenuhi kebutuhan pernapasan mereka.

Explanation
The exchange of carbon dioxide and oxygen in the human lungs occurs in the alveoli. These small air sacs are located at the end of the bronchioles and are surrounded by a network of capillaries. When we breathe in, oxygen from the air enters the alveoli and diffuses into the surrounding capillaries, where it binds to red blood cells. At the same time, carbon dioxide, which is a waste product produced by cells in the body, diffuses from the capillaries into the alveoli and is then exhaled out of the body when we breathe out. Therefore, the alveoli are responsible for the vital gas exchange process in the lungs.

Explanation
The correct answer is "paru-paru." Whales are mammals and, like other mammals, they breathe using lungs. They have large and powerful lungs that allow them to take in and store a large amount of oxygen. Whales come to the water's surface to exhale and inhale fresh air into their lungs. Their lungs are adapted to withstand the high pressures of diving deep underwater.

Explanation
The correct answer is "kulit." This suggests that the skin helps frogs breathe. Frogs have a unique respiratory system that allows them to breathe through their skin, in addition to using their lungs. The skin of a frog is thin and permeable, allowing oxygen to pass through and carbon dioxide to be released. This adaptation is important for frogs, especially when they are underwater or in environments with low oxygen levels.

Explanation
Manusia bernafas menggunakan paru-paru, yang berfungsi untuk mengambil oksigen dari udara dan mengeluarkan karbon dioksida. Paru-paru terletak di dalam dada dan terhubung dengan saluran pernapasan seperti trakea dan bronkus. Ketika manusia menghirup udara, oksigen masuk ke paru-paru melalui bronkus dan kemudian diserap oleh darah melalui pembuluh darah ke seluruh tubuh. Selama proses ini, karbon dioksida yang dihasilkan oleh tubuh dikeluarkan melalui paru-paru saat manusia menghembuskan napas.

Explanation
The correct answer is pleura. The explanation is that the question is asking for the thin layer that surrounds our lungs, which is called the pleura. The pleura acts as a protective covering for the lungs, helping to reduce friction during breathing.

Explanation
The correct answer is 3 because the question states that the human right lung consists of "gelambir." Gelambir is a term used to describe the lobes or segments of the lung. Therefore, the right lung of a human consists of three lobes or gelambir.

Explanation
Pada saat terbang, pernafasan burung dibantu oleh pundi-pundi udara. Pundi-pundi udara adalah ruang kosong yang terdapat di dalam tulang belakang burung yang berfungsi sebagai penyimpan udara tambahan. Ketika burung terbang, udara dari pundi-pundi udara akan mengalir ke paru-paru dan memungkinkan burung untuk bernapas dengan lebih efisien. Hal ini membantu burung dalam menjaga keseimbangan dan stabilitas saat terbang.

Explanation
The correct answer is "hidung tenggorokan bronkus bronkiolus alveolus." This is the correct order of the respiratory organs in a human. The air enters through the nose (hidung) and then passes through the throat (tenggorokan). From there, it enters the bronchi (bronkus), which are the main airways in the lungs. The bronchi then branch out into smaller tubes called bronchioles (bronkiolus), which lead to the alveoli (alveolus). The alveoli are tiny air sacs where the exchange of oxygen and carbon dioxide takes place.

Explanation
The correct answer is "karbondioksida dan uap air" because when we breathe, our body takes in oxygen and releases carbon dioxide as a waste product. Additionally, our breath also contains water vapor, which is a result of the moisture present in our respiratory system. Therefore, the two components mentioned in the answer are the main constituents of the exhaled breath.

Explanation
Penyakit pada organ pernapasan yang disebabkan oleh bakteri Corybacterium diptheriae adalah difteri.

Explanation
Influenza is a respiratory illness caused by the myxovirus. It is a common viral infection that affects the nose, throat, and lungs. Symptoms of influenza include fever, cough, sore throat, runny or stuffy nose, body aches, and fatigue. The myxovirus is responsible for the spread of influenza through respiratory droplets when an infected person coughs or sneezes. Therefore, influenza is the correct answer to the question.
