Questions and Answers
  • 1.

    • A.

      A. hati

    • B.

      B. kulit

    • C.

      C. ginjal

    • D.

      D. usus besar

    Correct Answer
    D. D. usus besar
    Explanation
    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.

    • B.

    • C.

    • D.

      D. bagian kulit yang berperan sebagai alat ekskresi adalah kelenjar keringat

    Correct Answer
    C. C. pankreas menghasilkan enzim amilase
    Explanation
    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.

    Sisa penyaringan pada proses filtrasi menghasilkan urine yang masih mengandung zat yang berguna bagi tubuh. Berikut ini yang bukan merupakan zat yang terdapat pada urine hasil proses filtrasi adalah

    • A.

      A. glukosa

    • B.

      B. asam amino

    • C.

      C. sel darah merah

    • D.

      D. garam-garam mineral

    Correct Answer
    C. C. sel darah merah
    Explanation
    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.

      C. asam amino dan amonia

    • D.

      D. karbon dioksida dan uap air

    Correct Answer
    D. D. karbon dioksida dan uap air
    Explanation
    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.

    Zat berikut yang tidak dihasilkan oleh hati adalah ....

    • A.

      A. urea

    • B.

      B. glukosa

    • C.

      C. bilirubin

    • D.

      D. getah empedu

    Correct Answer
    B. B. glukosa
    Explanation
    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.

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.
