Katub yang terletak antara atrium dan ventrikel
Correct Answer
D. Katub atrioventrikuler
Explanation
The correct answer is "katub atrioventrikuler" because it is the valve located between the atrium and ventricle. The term "atrioventrikuler" refers to the connection between the atrium and ventricle, indicating that this valve is responsible for regulating the flow of blood between these two chambers of the heart.
4.
Katub yang terletak antara atrium kanan dan ventrikel kanan
Correct Answer
C. Katub trikuspid
Explanation
The correct answer is "katub trikuspid." The explanation for this is that the tricuspid valve is located between the right atrium and the right ventricle in the heart. It consists of three cusps or flaps that open and close to regulate the flow of blood from the atrium to the ventricle. This valve prevents the backflow of blood into the atrium when the ventricle contracts, ensuring that blood flows in one direction through the heart.

Suatu kondisi dimana jantung berkontraksi disebut................
Correct Answer
B. Sistole
Explanation
The correct answer is "sistole". Sistole refers to the condition when the heart contracts. Diastole, on the other hand, refers to the condition when the heart relaxes. Therefore, in this question, the correct answer is "sistole" as it specifically mentions the contraction of the heart.
6.
Keadaan dimana jantung terelaksasi disebut
Correct Answer
B. Diastole
Explanation
Diastole adalah keadaan dimana jantung terelaksasi atau beristirahat setelah kontraksi. Pada saat diastole, otot jantung mengendur dan ruang-ruang jantung mengisi dengan darah yang masuk dari vena. Ini adalah fase di mana jantung mengisi ulang sebelum kontraksi berikutnya.
7.
Pembuluh darah yang berfungsi membawa darah meninggalkan jantung adalah ..............
Correct Answer
D. Arteri
Explanation
Arteries are blood vessels that carry oxygenated blood away from the heart to the rest of the body. They have thick, elastic walls that help to maintain blood pressure and allow for the efficient transportation of blood. In contrast, veins carry deoxygenated blood back to the heart. Vena, aotra, and ventrikel kiri are not correct answers as they do not accurately describe blood vessels that carry blood away from the heart.

Organ yang menyaring udara yang ke dalam hidung adalah
Correct Answer
A. Laring
Explanation
The correct answer is laring. The larynx, also known as the voice box, is an organ located in the throat that helps to filter the air that enters the nose. It contains vocal cords and plays a crucial role in producing sound and protecting the airway during swallowing.
9.
Katub yang berfungsi menutup laring sewaktu menelan adalah
Correct Answer
B. Epiglotis
Explanation
The correct answer is "epiglotis". The epiglottis is a flap of cartilage located at the base of the tongue that prevents food and drink from entering the windpipe (trachea) during swallowing. It covers the opening of the larynx (voice box) and directs the food and drink into the esophagus instead. The other options mentioned, such as "faring," "trikuspid," and "bikuspid," do not have a role in closing the larynx during swallowing.
10.
Organ tempat pertukaran oksigen dan karbon dioksida adalah ................
Correct Answer
B. Alveoli
Explanation
The correct answer is alveoli. The alveoli are tiny air sacs located at the end of the bronchioles in the lungs. They are responsible for the exchange of oxygen and carbon dioxide during the process of respiration. Oxygen from inhaled air enters the bloodstream through the walls of the alveoli, while carbon dioxide, a waste product, is expelled from the bloodstream into the alveoli to be exhaled. Therefore, the alveoli play a crucial role in the exchange of gases in the respiratory system.
11.
Membran timpani terletak di telinga bagian..................
Correct Answer
C. Tengah
Explanation
The correct answer is "tengah". The tympanic membrane, also known as the eardrum, is located in the middle part of the ear. It separates the outer ear from the middle ear and plays a crucial role in transmitting sound vibrations to the inner ear.
12.
Organ dalam sistem respirasi yang merupakan tempat pita suara ...........
Correct Answer
C. Laring
Explanation
The correct answer is "laring." The larynx, or laring in Indonesian, is the organ in the respiratory system that contains the vocal cords or pita suara. It is commonly known as the voice box and is responsible for producing sound and allowing us to speak.
13.
Tempat terjadinya penyerapan makanan adalah
Correct Answer
A. Ileum
Explanation
The ileum is the part of the small intestine where the absorption of nutrients from digested food takes place. It is the final section of the small intestine and is responsible for absorbing various substances such as vitamins, minerals, and bile salts. The duodenum is the first part of the small intestine where most of the digestion occurs, but absorption mainly happens in the ileum. The jejunum is the middle section of the small intestine and also plays a role in absorption. The stomach is primarily involved in the initial breakdown of food through the process of digestion, rather than absorption. Therefore, the correct answer is ileum.
14.
Tempat terjadinya pertukaran oksigen dan sari-sari makanan adalah
Correct Answer
A. Kapiler
Explanation
Kapiler adalah tempat terjadinya pertukaran oksigen dan sari-sari makanan di dalam tubuh. Kapiler adalah pembuluh darah yang sangat kecil dan tipis, sehingga memungkinkan oksigen dan nutrisi dari darah untuk melewati dindingnya dan masuk ke dalam jaringan tubuh. Selain itu, kapiler juga memungkinkan pembuangan karbon dioksida dan limbah metabolisme lainnya dari jaringan kembali ke dalam darah untuk dibawa ke organ pengeluaran seperti paru-paru atau ginjal.
15.
Darah yang berasal dari paru-paru masuk ke jantung melalui
Correct Answer
A. Atrium kiri
Explanation
The correct answer is Atrium kiri. The question is asking about the pathway of blood from the lungs to the heart. The blood that comes from the lungs is oxygen-rich and enters the heart through the left atrium. From there, it is pumped into the left ventricle and then circulated to the rest of the body. The right atrium and ventricle receive deoxygenated blood from the body and pump it to the lungs for oxygenation.
16.
Bagian dari jantung yang berfungsi memompa darah keseluruh tubuh.....
Correct Answer
A. Ventrikel kiri
Explanation
The left ventricle is responsible for pumping oxygenated blood to the entire body. It receives oxygen-rich blood from the left atrium and contracts forcefully to propel the blood into the aorta, which then distributes it to the rest of the body. This pumping action ensures that all organs and tissues receive the necessary oxygen and nutrients for proper functioning.
17.
Tempat penampungan urin disebut....
Correct Answer
A. Vesica Urinaria
Explanation
The correct answer is Vesica Urinaria. Vesica Urinaria is the Latin term for urinary bladder, which is the organ responsible for storing urine before it is eliminated from the body. The other options, ureter, urethra, and glomerulus, are all parts of the urinary system but do not specifically refer to the storage of urine.
18.
Hormon yang disekresi oleh sel beta pankreas adalah
Correct Answer
A. Insulin
Explanation
Insulin is the hormone secreted by the beta cells of the pancreas. It plays a crucial role in regulating blood sugar levels by facilitating the uptake and utilization of glucose by cells. Insulin helps to lower blood sugar levels by promoting the storage of glucose in the liver and muscles as glycogen. It also inhibits the breakdown of glycogen and stimulates the conversion of excess glucose into fat for long-term energy storage. Insulin deficiency or resistance can lead to diabetes, a condition characterized by high blood sugar levels.
19.
Tempat terjadinya filtrasi pada ginjal adalah
Correct Answer
A. Glomerulus
Explanation
The correct answer is the glomerulus. The glomerulus is a network of capillaries located in the renal corpuscle of the kidney. It is responsible for the initial filtration of blood, where waste products, excess ions, and water are filtered out of the blood and into the renal tubules. This filtration process is essential for the formation of urine and the removal of waste products from the body.
20.
Pacu jantung dimulai pada nodus....
Correct Answer
A. Sinoatrial
Explanation
The correct answer is "Sinoatrial." The sinoatrial node is responsible for initiating the heartbeat by generating electrical impulses. It is located in the right atrium of the heart and is often referred to as the "natural pacemaker" of the heart. The electrical impulses generated by the sinoatrial node travel through the atria, causing them to contract and pump blood into the ventricles. From there, the impulses are conducted to the atrioventricular node, which is responsible for transmitting the signals to the ventricles, leading to their contraction and the pumping of blood out of the heart.
