Soal IPA Materi SiSTEM Ekskresi

The correct answer is "Karbondioksida dan uap air". This is because carbon dioxide and water are the byproducts of cellular respiration, which is the metabolic process that occurs in cells to produce energy. Carbon dioxide is released as a waste product and is transported to the lungs where it is exhaled. Water vapor is also released through respiration and is expelled as moisture in the breath.

The question asks for an organ that is not involved in excretion in humans. The kidney is responsible for filtering waste products from the blood and producing urine, making it an excretory organ. The skin also plays a role in excretion by eliminating sweat and certain waste products. The liver is involved in the metabolism and detoxification of various substances, including the excretion of bile. However, the large intestine, or the colon, primarily absorbs water and electrolytes from undigested food, rather than excreting waste products. Therefore, the large intestine is the correct answer as it is not directly involved in excretion.

The correct answer is "Mempunyai kelenjar keringat" because the skin acts as an excretory organ by producing sweat through sweat glands. Sweat helps regulate body temperature and eliminates waste products such as toxins and excess salts from the body.

The given options are ways to maintain a healthy heart. Drinking enough water, reducing high-fat foods, and regularly consuming antioxidants are all beneficial for heart health. However, consuming alcohol regularly is not a recommended way to keep the heart functioning normally. Excessive alcohol consumption can lead to various heart problems and negatively impact overall health.

The correct answer is "Urin primer." The filtration stage in urine formation involves the initial process of filtering blood in the kidneys to form a fluid called urine. This fluid, known as urine primer, contains waste products, excess water, and electrolytes that are filtered out from the blood. It is the first stage in urine formation before further processing occurs in the kidneys to produce the final urine product.

The given statements are all related to different organs and their functions in the human body. The skin produces sweat, the kidneys produce urine, and the liver produces bile. However, the pancreas is not involved in the production of sweat, urine, or bile. Instead, it produces the enzyme amylase, which is involved in the digestion of carbohydrates.

Glukosa tidak dihasilkan oleh hati. Hati memproduksi urea, zat warna empedu, dan bilirubin, tetapi tidak memproduksi glukosa. Glukosa adalah bentuk energi yang diperoleh dari makanan dan disimpan dalam tubuh. Hati berperan dalam menyimpan dan melepaskan glukosa ke dalam darah sesuai kebutuhan tubuh.

The correct answer is "Tubulus kontortus proksimal." In the formation of urine, the process of reabsorption takes place in the proximal convoluted tubule. This is where most of the water, glucose, amino acids, and ions are reabsorbed from the filtrate back into the bloodstream. The proximal convoluted tubule is located after the glomerulus, which is where filtration occurs, and before the distal convoluted tubule. Therefore, the correct answer is the proximal convoluted tubule.

The explanation for the given correct answer is that diabetes insipidus is caused by a deficiency of the hormone ADH (Anti Diuretic Hormone). ADH plays a crucial role in regulating the body's water balance by controlling the amount of water reabsorbed by the kidneys. In diabetes insipidus, the body is unable to properly regulate water levels, leading to excessive thirst and urination. This condition can be caused by a lack of ADH production by the hypothalamus or a failure of the kidneys to respond to ADH.

Nefritis is the correct answer because it refers to the inflammation of the glomeruli in the kidneys, which can be caused by an allergic reaction to bacterial toxins. This inflammation can lead to damage in the glomeruli and affect their function in filtering waste products from the blood.
