The correct answer is "kanan dan kiri tulang pinggang". The kidneys are located in the abdominal cavity, specifically on the right and left sides of the waist, near the lower back.
4.
Organ berikut ini termasuk dalam sistem ekskresi, kecuali ... .
Correct Answer
B. Pankreas
Explanation
The pancreas is not part of the excretory system. It is primarily involved in the production and secretion of digestive enzymes and hormones such as insulin. The excretory system, on the other hand, is responsible for removing waste products from the body, particularly through the urine. The kidneys play a major role in this process by filtering the blood and producing urine. The liver also plays a role in detoxification and waste removal. The skin, through sweating, can also eliminate certain waste products. Therefore, the correct answer is pankreas.

Correct Answer
A. Glomerulus
Explanation
The correct answer is glomerulus. The glomerulus is a part of the Bowman's capsule in the kidney. It is responsible for filtering waste products and excess fluid from the blood to form urine. The Bowman's capsule, along with the glomerulus, plays a crucial role in the process of urine formation in the kidneys.
6.
Saluran urine yang keluar dari ginjal disebut ... .
Correct Answer
C. Ureter
Explanation
The correct answer is "ureter." The ureter is the tube that carries urine from the kidneys to the bladder. It is responsible for transporting urine that has been filtered by the kidneys and ensuring it reaches the bladder for storage and eventual elimination from the body. The other options, medula, uretra, and pelvis, are not correct as they do not refer to the specific tube that carries urine from the kidneys.

Correct Answer
C. Hati
Explanation
The liver is not directly involved in the excretion of excess water from the body. The kidneys are responsible for filtering waste products, including excess water, from the blood and excreting them as urine. The lungs are responsible for removing carbon dioxide from the body during respiration. The skin can also excrete small amounts of water through sweat glands. However, the liver primarily plays a role in detoxification, metabolism, and the production of bile.
9.
Bagian ginjal yang berfungsi untuk menyaring darah adalah ... .
Correct Answer
A. Kulit ginjal
Explanation
The correct answer is "kulit ginjal" because the kidney cortex, or kulit ginjal, is the outer part of the kidney that contains the nephrons. Nephrons are the functional units of the kidney responsible for filtering waste products and excess water from the blood to form urine. Therefore, the kidney cortex plays a crucial role in the filtration process and is responsible for filtering the blood to remove waste products.
10.
Tahap filtrasi pembentukan urine terjadi pada ginjal adalah ... .
Correct Answer
C. Badan malpighi
Explanation
The correct answer is badan malpighi. The filtration stage of urine formation occurs in the glomerulus, which is part of the renal corpuscle or the badan malpighi. This is where blood is filtered and the filtrate is formed. The filtrate then moves on to the next stages of urine formation, including reabsorption and secretion.

13.
Pernyataan berikut berhubungan dengan sistem pengeluaran pada manusia, kecuali ... .
Correct Answer
D. Pankreas menghasilkan enzim amilase
Explanation
The statement "pankreas menghasilkan enzim amilase" is the correct answer because it is the only statement that does not relate to the excretory system in humans. The other statements mention the organs and processes involved in the excretion of waste products, such as sweat produced by the skin, urine produced by the kidneys, and the sweat glands in the skin acting as excretory organs. However, the pancreas is not directly involved in the excretory system but rather plays a role in digestion by producing enzymes like amylase.
14.
Penyakit gula atau kencing manis disebut juga ... .
Correct Answer
B. Diabetes mellitus
Explanation
The correct answer is diabetes mellitus. Diabetes mellitus is another term for the disease known as gula or kencing manis. It is a chronic condition characterized by high levels of sugar in the blood due to the body's inability to produce or effectively use insulin.
15.
Zat sisa metabolisme yang dikeluarkan melalui paru-paru adalah ... .
Correct Answer
D. Karbondioksida dan uap air
Explanation
The correct answer is "karbondioksida dan uap air" because when we breathe, our body releases carbon dioxide (karbondioksida) as a waste product of metabolism. Additionally, water vapor (uap air) is also expelled through the lungs during respiration.
16.
Selain sebagai alat pengeluaran, kulit manusia juga mempunyai fungsi sebagai berikut, kecuali ... .
Correct Answer
A. Mengatur kadar gula dalam darah
Explanation
The human skin has various functions, including regulating body temperature, forming vitamin D, and serving as a sense of touch. However, it does not have the function of regulating blood sugar levels. This function is primarily carried out by the pancreas, which produces insulin to control blood sugar levels.
17.
Sisa penyaringan pada proses filtrasi menghasilkan urine yang masih mengandung zat yang berguna bagi tubuh, kecuali ... .
Correct Answer
B. Sel darah merah
Explanation
During the process of filtration, the kidneys remove waste products and excess fluids from the blood to produce urine. However, certain substances that are beneficial for the body, such as glucose, mineral salts, and amino acids, are reabsorbed back into the bloodstream. The exception to this is red blood cells, which are not reabsorbed and are instead eliminated in the urine. Therefore, the correct answer is "red blood cells."
18.
Jumlah urine yang dikeluarkan dari tubuh dipengaruhi oleh ... .
Correct Answer
C. Banyaknya cairan yang diminum
Explanation
The amount of urine produced by the body is influenced by the amount of fluid consumed. When a person drinks more fluids, it increases the volume of urine that is produced. This is because the body needs to eliminate the excess fluid that is not needed for hydration. On the other hand, if a person does not consume enough fluids, the body conserves water and produces less urine to prevent dehydration. Therefore, the amount of fluid intake directly affects the amount of urine output.
19.
Agar suhu tetap, tubuh akan mengeluarkan ... .
Correct Answer
A. Keringat
Explanation
When the body temperature remains constant, the body will release sweat. Sweat is produced by sweat glands in the skin and helps to regulate body temperature by evaporating and cooling the skin. This is an important mechanism for the body to maintain its internal temperature within a narrow range, especially during physical activity or in hot environments. Therefore, the correct answer is keringat.
20.

Correct Answer
A. Glomerulus
Explanation
Infeksi kuman pada nefritis menyebabkan kerusakan pada glomerulus. Glomerulus adalah bagian dari ginjal yang berperan dalam penyaringan darah. Ketika terjadi infeksi kuman pada nefritis, glomerulus dapat mengalami kerusakan yang mengganggu kemampuannya dalam menyaring darah dan mengeluarkan limbah. Oleh karena itu, glomerulus merupakan bagian yang paling terdampak dalam kasus infeksi kuman pada nefritis.
21.
Diabetes mellitus dapat terjadi karena ... .
Correct Answer
A. Nefron gagal menyerap kelebihan glukosa
Explanation
Diabetes mellitus occurs when the nephrons in the kidneys fail to absorb excess glucose from the bloodstream. This leads to high levels of glucose in the blood, which can cause various complications in the body. The pancreas producing insulin is not the cause of diabetes mellitus, as insulin is necessary to regulate blood sugar levels. Excess salt in the blood and the presence of bacterial infection in the glomerulus do not directly cause diabetes mellitus.
22.
Kulit berfungsi sebagai alat ekskresi karena ... .
Correct Answer
B. Mempunyai kelenjar keringat
Explanation
Kulit berfungsi sebagai alat ekskresi karena mempunyai kelenjar keringat. Kelenjar keringat pada kulit membantu mengeluarkan zat-zat sisa seperti air, garam, dan urea melalui proses pengeluaran keringat. Proses ini membantu menjaga keseimbangan suhu tubuh dan mengeluarkan zat-zat yang tidak diperlukan oleh tubuh.
23.
Adanya batu ginjal di dalam rongga ginjal dapat menimbulkan ... .
Correct Answer
D. Hidronefrosis
Explanation
Hidronefrosis is the correct answer because it refers to the condition where there is a blockage in the urinary tract that prevents urine from flowing properly, causing the kidneys to become swollen and distended. This can be caused by the presence of kidney stones in the renal cavity, leading to the accumulation of urine and subsequent enlargement of the kidneys. Diabetes insipidus, hematuria, and nephritis are unrelated conditions and do not directly result from the presence of kidney stones in the renal cavity.

Correct Answer
B. 2
Explanation
The correct answer is 2 because in the image, there is a structure labeled as "liver" which is responsible for filtering and processing waste products, including the breakdown of red blood cells. Therefore, the waste material expelled by the liver originates from the breakdown of red blood cells.
26.
Hati terletak di dalam ... .
Correct Answer
B. Rongga perut sebelah kanan, di bawah diafragma
Explanation
The correct answer is "rongga perut sebelah kanan, di bawah diafragma" which translates to "the right side of the abdominal cavity, below the diaphragm." This is because the heart is located in the thoracic cavity, specifically in the mediastinum, which is in the center of the chest. It is not located in the left or right side of the abdominal cavity or above the diaphragm.
27.
Fungsi hati berikut berkaitan dengan sistem pengeluaran, kecuali ... .
Correct Answer
D. Membongkar jenis protein tertentu
Explanation
The liver performs various functions related to the excretory system, such as converting provitamin A into vitamin A, storing glucose in the form of glycogen, and breaking down certain types of proteins. However, it does not play a role in converting damaged red blood cells into bile.

Perhatikan pernyataan berikut :1. CO22. O23. H2O4. COParu-paru sebagai organ pengeluaran
sisa-sisa pembakaran berupa ... .
Correct Answer
B. 1 dan 3
Explanation
Paru-paru berperan dalam proses pertukaran gas di dalam tubuh. CO2 (karbon dioksida) adalah hasil sisa pembakaran dalam tubuh, yang kemudian dikeluarkan melalui paru-paru. O2 (oksigen) adalah gas yang dihirup oleh paru-paru dan digunakan oleh sel-sel tubuh untuk respirasi. H2O (air) juga merupakan hasil sisa pembakaran yang dikeluarkan melalui paru-paru dalam bentuk uap air. Oleh karena itu, pernyataan 1 dan 3 adalah benar.
30.
Yang merupakan zat-zat yang dapat membentuk batu ginjal adalah ... .
Correct Answer
B. Kalsium
Explanation
Kalsium merupakan zat yang dapat membentuk batu ginjal. Batu ginjal terbentuk ketika kalsium dalam urine mengendap dan membentuk kristal yang kemudian berkumpul menjadi batu ginjal. Faktor-faktor lain seperti kekurangan air, kelebihan garam, dan ketidakseimbangan zat-zat dalam urine juga dapat mempengaruhi pembentukan batu ginjal.
31.
Pasangan yang tepat antara organ ekskresi dan zat yang dikeluarkannya seperti di bawah ini, kecuali ... .
Correct Answer
D. Paru-paru dan oksigen
Explanation
The correct answer is "paru-paru dan oksigen" because the lungs are not an excretory organ. The lungs are responsible for the exchange of gases, taking in oxygen and releasing carbon dioxide. Excretion refers to the removal of waste products from the body, and the lungs do not excrete any substances.
32.
Sebagai alat ekskresi, kulit dilengkapi dengan ... .
Correct Answer
C. Kelenjar keringat
Explanation
The correct answer is "kelenjar keringat" because as an excretory organ, the skin is equipped with sweat glands. These glands are responsible for producing sweat, which helps regulate body temperature and eliminate waste products from the body.
33.
Jika urine seseorang mengandung glukosa,
diperkirakan bagian ginjal yang terganggu adalah ... .
Correct Answer
D. Lengkung Henle
Explanation
The correct answer is lengkung Henle. The presence of glucose in urine indicates that the kidney's ability to reabsorb glucose is impaired. The glomerulus and Bowman's capsule are responsible for filtration, while the proximal tubule is responsible for reabsorption of glucose. The loop of Henle is responsible for reabsorption of water and electrolytes, not glucose. Therefore, if glucose is present in urine, it suggests that the loop of Henle is not functioning properly.
34.
Penyebab penyakit atau gangguan pada ginjal yang
