Gangguan pada Sistem Sirkulasi Manusia Sistem sirkulasi berfungsi mengedarkan darah, oksigen, dan zat makanan ke seluruh tubuh serta mengangkut sisa metabolisme. Jika sistem ini terganggu, tubuh bisa cepat lelah, sakit, bahkan berbahaya. Berikut gangguan-gangguannya: 1. Anemia Anemia, yaitu keadaan di mana jumlah eritrosit di dalam hemoglobin di bawah batas normal. Artinya: Anemia adalah kondisi ketika sel darah merah atau hemoglobin dalam tubuh kurang, sehingga darah tidak mampu membawa oksigen dengan baik ke seluruh tubuh. Akibatnya: Penderita anemia mudah lelah, pusing, lemas, dan terlihat pucat karena tubuh kekurangan oksigen. Contoh dalam kehidupan sehari-hari: Seseorang cepat capek saat beraktivitas, mudah mengantuk di sekolah, dan merasa lemas meskipun tidak melakukan aktivitas berat. 2. Hemofilia Hemofilia adalah kelainan yang ditandai dengan sulitnya darah untuk membeku. Penyakit keturunan ini disebabkan oleh defisiensi faktor pembekuan darah. Artinya: Hemofilia merupakan penyakit bawaan yang menyebabkan darah sulit berhenti ketika terjadi luka. Akibatnya: Luka kecil dapat menyebabkan perdarahan yang lama dan berisiko berbahaya jika tidak ditangani. Contoh dalam kehidupan sehari-hari: Saat penderita tergores atau jatuh, darah keluar lebih lama dibandingkan orang normal meskipun lukanya kecil. 3. Talasemia Talasemia adalah kelainan pada bentuk eritrosit. Akibatnya, eritrosit di dalam tubuh penderita akan mudah rusak, rapuh, dan kurang optimal dalam mengikat oksigen. Artinya: Talasemia merupakan penyakit keturunan yang memengaruhi bentuk dan fungsi sel darah merah. Akibatnya: Tubuh menjadi cepat lelah, pertumbuhan terganggu, dan penderita sering membutuhkan transfusi darah. Contoh dalam kehidupan sehari-hari: Anak dengan talasemia terlihat kurang aktif dan harus rutin memeriksakan diri ke rumah sakit. 4. Hipotensi (Tekanan darah rendah) Hipotensi adalah keadaan di mana tekanan darah arteri menurun sampai di bawah batas normal, misalnya 90/60 mmHg untuk sistol/diastol. Artinya: Hipotensi adalah kondisi tekanan darah terlalu rendah. Akibatnya: Penderita dapat mengalami pusing, lemas, dan bahkan pingsan. Contoh dalam kehidupan sehari-hari: Seseorang merasa pusing saat berdiri terlalu cepat setelah duduk atau berbaring. 5. Hipertensi (Tekanan darah tinggi) Hipertensi adalah keadaan di mana tekanan darah arteri meningkat sampai di atas normal, misalnya 140/90 mmHg. Keadaan ini bisa disebut tekanan darah tinggi. Artinya: Hipertensi adalah kondisi tekanan darah lebih tinggi dari batas normal. Akibatnya: Dapat menyebabkan sakit kepala, gangguan jantung, stroke, dan kerusakan pembuluh darah jika tidak dikontrol. Contoh dalam kehidupan sehari-hari: Orang yang sering makan makanan asin, jarang berolahraga, dan sering stres lebih berisiko mengalami hipertensi. 6. Trombus Trombus adalah kelainan di mana terdapat gumpalan darah yang menyumbat pembuluh darah. Artinya: Trombus adalah penggumpalan darah yang menghambat aliran darah di dalam pembuluh. Akibatnya: Aliran darah menjadi tidak lancar dan dapat menyebabkan kerusakan organ. Contoh dalam kehidupan sehari-hari: Orang yang duduk terlalu lama tanpa bergerak berisiko mengalami penggumpalan darah di kaki. 7. Varises Varises adalah kelainan yang disebabkan oleh pelebaran pembuluh vena. Pelebaran biasa terjadi di anggota tubuh bagian bawah, contohnya betis. Artinya: Varises terjadi ketika pembuluh darah vena melebar karena aliran darah tidak lancar. Akibatnya: Kaki terasa pegal, berat, dan pembuluh darah tampak menonjol. Contoh dalam kehidupan sehari-hari: Sering dialami oleh orang yang berdiri terlalu lama seperti guru, pedagang, atau perawat.

What is the correct value of the mean? A. 118 B. 119 C. 120 D. 121 Without calculating variance fully, which park is most likely to have the larger population variance? A. Park A, because its values are closer to the mean B. Park B, because its values are more spread out C. Park A, because it has a smaller range D. Park B, because it has more visitors overall The mean number of visitors for both parks is 120. Which value contributes the MOST to the variance of Park B? A. 110 B. 120 C. 130 D. 150 What is the squared deviation of 90 visitors from the mean? A. 30 B. 60 C. 900 D. 30² Why does the value 150 increase the variance more than 130? A. It increases the mean B. Its deviation from the mean is larger before squaring C. It occurs later in the data set D. Variance depends only on the largest value Which statement best describes the visitor pattern in Park A (Sharjah)? A. Highly variable with extreme values B. Random and unpredictable C. Consistent with small deviations from the mean D. Skewed due to an outlier Both parks have the same mean. Why is variance still needed to compare them? A. The mean does not show how spread out the data is B. Variance changes the data values C. Variance affects the mean D. Variance replaces the mean A municipality wants to plan staffing using predictable visitor numbers. Based on variance, which park should be chosen? A. Park B, because it has higher peaks B. Park A, because it has lower variance C. Park B, because it has more visitors D. Either park, since the means are equal A student says: “Park B has greater variation because it has the largest value.” Which response best evaluates this claim? A. Correct, because variance depends only on the maximum value B. Partially correct, because variance depends on all deviations from the mean C. Incorrect, because variance ignores extreme values D. Incorrect, because variance only uses the mean If the value 150 were removed from Park B’s data, what would most likely happen to its variance? A. It would increase B. It would stay the same C. It would decrease D. It would become zero
