Darah adalah salah satu bagian penting dari tubuh manusia. Organ tubuh manusia yang memompa darah agar tetap mengalir adalah ....
Correct Answer
B. Jantung
Explanation
The heart is responsible for pumping blood throughout the body, making it a vital organ. It ensures that oxygenated blood is circulated to all the cells and tissues, while also removing waste products. Without the heart's continuous pumping action, blood would not flow, and the body's organs and tissues would not receive the necessary oxygen and nutrients. Therefore, the heart plays a crucial role in maintaining the circulation of blood in the human body.

Explanation
When blood flows throughout the body, it also carries oxygen along with it. Oxygen is an essential component for various bodily functions, including cellular respiration and energy production. It is transported by red blood cells and delivered to different tissues and organs, ensuring their proper functioning. Therefore, the correct answer is "Oksigen."

Mengalirnya darah ke seluruh tubuh dinamakan sistem ....
Correct Answer
D. Peredaran darah
Explanation
Peredaran darah adalah istilah yang digunakan untuk menggambarkan aliran darah yang terjadi di seluruh tubuh manusia. Sistem peredaran darah melibatkan jantung sebagai pompa utama yang memompa darah ke seluruh tubuh melalui pembuluh darah. Darah mengangkut oksigen, nutrisi, dan zat-zat lain yang dibutuhkan oleh sel-sel tubuh, serta mengangkut sisa-sisa metabolisme yang perlu dikeluarkan dari tubuh. Dengan adanya peredaran darah yang baik, sel-sel tubuh dapat berfungsi dengan baik dan menjaga kesehatan tubuh secara keseluruhan.

Sistem peredaran darah kecil mengalir dari ....
Correct Answer
A. Bilik kanan menuju paru-paru
Explanation
The correct answer is "Bilik kanan menuju paru-paru" (The right ventricle flows to the lungs). This is because the right ventricle is responsible for pumping deoxygenated blood to the lungs where it can be oxygenated. Once the blood is oxygenated in the lungs, it returns to the heart's left atrium and then flows into the left ventricle before being pumped out to the rest of the body.

Darah yang telah mengalir kembali ke jantung dari seluruh tubuh banyak mengandung ....
Correct Answer
C. Karbondioksida
Explanation
Darah yang telah mengalir kembali ke jantung dari seluruh tubuh banyak mengandung karbondioksida. Karbondioksida adalah gas buangan yang dihasilkan oleh sel-sel tubuh saat mereka melakukan respirasi seluler. Setelah darah mengambil oksigen dari paru-paru, ia mengalir ke seluruh tubuh dan mengambil karbondioksida dari sel-sel. Darah kemudian membawa karbondioksida kembali ke jantung untuk dikirim ke paru-paru dan dibuang melalui pernapasan.

The miokardium is composed of specialized cardiac muscle cells that are capable of generating electrical impulses and coordinating the rhythmic contractions of the heart.
7.
Tempat pertukaran oksigen dan karbondioksida dalam paru-paru terjadi di ....
Correct Answer
D. Alveolus
Explanation
The exchange of oxygen and carbon dioxide occurs in the alveoli. Alveoli are tiny air sacs located at the end of the bronchioles in the lungs. They are surrounded by a network of blood vessels called capillaries. When we inhale, oxygen enters the alveoli and diffuses into the bloodstream through the thin walls of the capillaries. At the same time, carbon dioxide, a waste product of cellular respiration, diffuses from the bloodstream into the alveoli to be exhaled. Therefore, the alveoli are the site where the exchange of gases takes place in the lungs.
