Ulangan Harian SiSTEM Ekskresi Kelas Ix

The given options list various organs involved in the excretion process in humans. However, the heart is not an organ of excretion. It is a muscular organ responsible for pumping blood throughout the body. Therefore, the heart is the exception in this list of excretory organs.

Penyakit yang ditandai dengan adanya gula dalam urine adalah diabetes mellitus. Diabetes mellitus adalah kondisi di mana tubuh tidak dapat menghasilkan atau menggunakan insulin dengan efektif, yang menyebabkan peningkatan kadar gula darah. Kondisi ini dapat menyebabkan gula darah yang tinggi terdeteksi dalam urine, yang dikenal sebagai glukosuria. Oleh karena itu, diabetes mellitus adalah jawaban yang tepat untuk pertanyaan ini.

The correct answer is empedu. Empedu is a waste product that is produced by the liver and stored in the gallbladder. It is released into the small intestine to help with the digestion and absorption of fats. Urine is produced by the kidneys and excreted through the urinary system. Karbondioksida is a waste product that is produced during cellular respiration and exhaled through the lungs. Uap air refers to water vapor, which is not a waste product of the body. Therefore, the correct answer is empedu.

Kulit tidak berfungsi untuk membentuk vitamin A dari provitamin A. Fungsi utama kulit adalah sebagai pelindung dari gangguan fisik, kimia, dan biologi, mengatur suhu tubuh, dan sebagai alat pengeluaran keringat.

The correct answer is 2 because in the given image, the number 2 is located next to a structure that resembles a kidney. The process of blood filtration occurs in the kidneys, where waste products and excess water are removed from the blood to form urine. Therefore, it can be inferred that the number 2 represents the location where the blood filtration process takes place.

The correct answer is "filtrasi-reabsorbsi-augmentasi". This is the correct sequence of steps in urine formation in the kidney. Filtrasi refers to the initial step where blood is filtered in the glomerulus, allowing small molecules and waste products to enter the renal tubules. Reabsorbsi is the next step, where essential substances such as water, glucose, and ions are reabsorbed back into the bloodstream from the renal tubules. Finally, augmentasi occurs, which is the process of concentrating the urine by reabsorbing more water and excreting concentrated urine.

The correct answer is mengeluarkan CO2 dan H2O. The lungs are responsible for removing carbon dioxide (CO2) from the body and releasing it into the atmosphere during exhalation. Additionally, water vapor (H2O) is also expelled from the lungs as a byproduct of respiration.

The incorrect statement about the kidney is that it is located below the right diaphragm. The kidneys are actually located on either side of the spine, just below the rib cage. They are not positioned below the diaphragm.

The correct answer is "paru-paru mengeluarkan CO2". This is because the experiment aims to prove that the lungs release carbon dioxide (CO2).

The correct answer is "menyaring darah". The function of the kidneys is to filter and remove waste products, toxins, and excess fluids from the blood through the process of filtration. The kidneys play a crucial role in maintaining the balance of electrolytes, regulating blood pressure, and producing urine. They help in removing metabolic waste products and maintaining the overall homeostasis of the body.

The correct answer is 3 because in the given image, the structure labeled with number 3 corresponds to the ureter. The ureter is a tube-like structure that carries urine from the kidneys to the urinary bladder.

During the process of urine formation, reabsorption occurs in the nephron. The correct answer is the proximal convoluted tubule. This is because the proximal convoluted tubule is responsible for the majority of reabsorption in the nephron. It reabsorbs important substances such as glucose, amino acids, and water back into the bloodstream, while also removing waste products.

The correct answer is korteks. The process of blood filtration in the kidney occurs in the renal cortex. This is where the glomerulus, a network of tiny blood vessels, filters waste products and excess fluids from the blood. The filtered blood then flows into the renal medulla, where further processing and reabsorption of essential substances occur before the urine is formed and transported to the pelvis and ureter for elimination.

Prolonged diabetes can lead to kidney failure.

The liver is an organ in the human body that performs various functions, including regulating blood sugar levels. It helps to maintain a balanced level of glucose in the bloodstream by storing excess glucose as glycogen and releasing it when the body needs energy. The liver also produces and releases insulin and glucagon hormones, which play a crucial role in controlling blood sugar levels. Therefore, the liver is responsible for both regulating blood sugar levels and performing other essential functions in the body.

The correct answer is tabung reaksi dan kapur. The reason for this is that a tabung reaksi (test tube) is used to collect the gas emitted by the lungs, and kapur (lime) is used to absorb the carbon dioxide in the gas. This setup allows for the detection and measurement of the gas released by the lungs. Kertas kobalt (cobalt paper) and cermin (mirror) are not necessary for this experiment, and kertas kobalt and air kapur (lime water) do not provide a means to collect and analyze the gas.

The correct answer is 3 because the image is not provided, so it is not possible to determine the exact location of the nephron in the given options.

When a mirror is blown on, it becomes foggy. This demonstrates that the lungs release carbon dioxide.

The given data suggests that the substance released by the skin is "air".
