SiSTEM Ekskresi Kelas 8

The correct answer is D. usus besar. The large intestine, or the colon, is not an excretory organ. It is responsible for absorbing water and electrolytes from undigested food and eliminating solid waste from the body. Excretion, on the other hand, is the process of eliminating metabolic waste products from the body, which is primarily done by organs like the liver, kidneys, and skin. Therefore, the large intestine does not play a role in excretion and is not considered an excretory organ.

The correct answer is D. karbon dioksida dan uap air. During metabolism, the cells produce carbon dioxide as a waste product. This carbon dioxide is transported to the lungs through the bloodstream and then exhaled. Additionally, water vapor is also released through the lungs during respiration. Therefore, the metabolic waste products that are expelled through the lungs are carbon dioxide and water vapor.

Kulit berfungsi sebagai alat ekskresi karena mempunyai kelenjar keringat. Kelenjar keringat membantu mengeluarkan zat-zat sisa dari tubuh seperti air, garam, dan urea melalui proses berkeringat. Ini adalah salah satu cara penting bagi tubuh untuk menjaga keseimbangan suhu dan menghilangkan limbah yang tidak diperlukan.

The correct answer is C. pankreas menghasilkan enzim amilase. This statement is unrelated to the human excretory system because the pancreas is not directly involved in the process of excretion. The pancreas is primarily responsible for producing digestive enzymes, including amylase, which helps break down carbohydrates in the digestive system. The excretory system, on the other hand, involves organs such as the kidneys and skin, which eliminate waste products from the body.

The image shows a diagram of the urinary system. Number 3 is pointing to the bladder, which is the organ that stores urine before it is expelled from the body. Therefore, the correct answer is C. 3.

Bagian yang berperan dalam proses pembentukan urine primer adalah A. 1.

The correct answer is C. sel darah merah. Sel darah merah (red blood cells) are not normally found in urine. The filtration process in the kidneys is responsible for removing waste products and excess substances from the blood, while retaining necessary substances such as glucose, amino acids, and mineral salts. Therefore, the presence of red blood cells in urine would indicate a potential health issue such as urinary tract infection, kidney disease, or injury to the urinary system.

Glukosa tidak dihasilkan oleh hati, melainkan oleh proses metabolisme karbohidrat di dalam tubuh. Hati memproduksi urea, bilirubin, dan getah empedu. Urea adalah produk akhir metabolisme protein yang dihasilkan oleh hati. Bilirubin adalah pigmen kuning yang dihasilkan oleh hati sebagai hasil pemecahan hemoglobin. Getah empedu adalah cairan yang diproduksi oleh hati dan disimpan di dalam kantong empedu, yang berfungsi untuk membantu pencernaan lemak.

The presence of a high glucose concentration in urine, as indicated by a 1.5% glucose level, suggests that the person may be suffering from diabetes mellitus. In this condition, the body is unable to properly regulate blood sugar levels, leading to high glucose levels in the urine. This is a common symptom of diabetes mellitus and can help in diagnosing the disease.

The presence of kidney stones in the kidney can cause hematuria, which is the presence of blood in the urine. Kidney stones can damage the lining of the urinary tract, causing bleeding and resulting in blood being visible in the urine. This can be a painful condition and may require medical intervention to treat the kidney stones and alleviate the symptoms.
