Pada proses penggumpalan darah, perubahan protrombin menjadi trombin dipicu oleh ion ... .
- A.
Na+
- B.
Fe
- C.
Ca2+
- D.
K+
- E.
Cl
Correct Answer
C. Ca2+Explanation
In the process of blood clotting, the conversion of prothrombin to thrombin is triggered by the ion Ca2+. Calcium ions play a crucial role in the coagulation cascade by binding to specific proteins and activating them. This activation leads to the formation of thrombin, which then converts fibrinogen into fibrin, the main component of blood clots. Without the presence of Ca2+, the clotting process would be impaired and blood would not be able to coagulate properly.Rate this question:

Aglutinogen darah dan aglutinin
Correct Answer
E. Aglutinogen darah dan aglutininExplanation
The correct answer is "aglutinogen darah dan aglutinin". This answer is correct because the ABO blood group system is based on the presence of two antigens (aglutinogens) on the surface of red blood cells, known as A and B, and the presence of two corresponding antibodies (aglutinins) in the plasma, known as anti-A and anti-B. The combination of these antigens and antibodies determines the blood type, whether it is A, B, AB, or O. Therefore, the ABO blood group system is based on the presence or absence of these antigens and antibodies in the blood.Rate this question:

Correct Answer
D. Aglutinin b menggumpalkan aglutinogen BExplanation
According to the given blood transfusion table, blood type A can receive blood from type A and type O donors. However, it cannot receive blood from type B donors because agglutinin B in blood type A will cause agglutination with agglutinogen B in blood type B. Therefore, the correct answer is "Aglutinin b menggumpalkan aglutinogen B" which means agglutinin B causes agglutination with agglutinogen B.Rate this question:

Correct Answer
B. Nodus aurikularis – nodus sinoaurikularis – otot serambi – atrioventrikularis – berkas His – sistem Purkinje – otot ventrikelExplanation
The correct answer is Nodus aurikularis – nodus sinoaurikularis – otot serambi – atrioventrikularis – berkas His – sistem Purkinje – otot ventrikel. This sequence accurately represents the pathway of the nerve impulses that trigger the heartbeat. The impulse starts at the sinoatrial (SA) node, then travels to the atrial nodes, followed by the atrial muscles, atrioventricular (AV) node, bundle of His, Purkinje system, and finally the ventricular muscles. This sequence ensures the coordinated contraction of the heart chambers, allowing for efficient blood circulation.Rate this question:

Alat untuk mengukur tekanan darah disebut … .
- A.
Respirometer
- B.
Termometer
- C.
Sphygmomanometer
- D.
Stetoskop
- E.
Mikroskop
Correct Answer
C. SphygmomanometerExplanation
A sphygmomanometer is a device used to measure blood pressure. It consists of an inflatable cuff that is wrapped around the upper arm, a pressure gauge, and a stethoscope or electronic sensor. When the cuff is inflated, it temporarily cuts off blood flow through the brachial artery. As the pressure in the cuff is released, blood flow resumes and the pressure at which the first sound is heard through the stethoscope or detected by the sensor is recorded as the systolic blood pressure. The pressure at which the sound disappears is recorded as the diastolic blood pressure. Therefore, a sphygmomanometer is the correct tool for measuring blood pressure.Rate this question:
