Questions and Answers

1.

Berikut ini adalah zat yang dilepaskan saat terjadinya alergi adalah....
- A.
  
  Antitoksin
- B.
  
  Presipitin
- C.
  
  Inerferon
- D.
  
  Gammaglobulin
- E.
  
  Histamin
Correct Answer
E. Histamin

Explanation
Histamin is the substance released during an allergic reaction. It is responsible for causing various symptoms such as itching, swelling, redness, and inflammation. When an allergen triggers an immune response, mast cells release histamine into the bloodstream, leading to the allergic symptoms. Antitoksin, presipitin, interferon, and gammaglobulin are not directly involved in allergic reactions.

Fungsi sistem limfa adalah mengabsorpsi lemek dan lakteal di usus halus kemudian mengangkutnya ke darah
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The statement is true because the lymphatic system plays a crucial role in absorbing fats and lacteals from the small intestine and transporting them into the bloodstream. The lymphatic vessels in the small intestine called lacteals absorb dietary fats and transport them as chylomicrons, which are large lipid droplets, into the lymphatic system. These chylomicrons are then carried by the lymphatic vessels and eventually emptied into the bloodstream, where they can be utilized by the body for energy or stored as fat. Therefore, the statement accurately describes the function of the lymphatic system.

4.

Sisitem kekebalan mencakup kekebalan bawaan dan kekebalan adaptif. Di bawah ini yang termasuk Kekebalan adaptif adalah....
- A.
  
  Kulit
- B.
  
  Membran mukosa
- C.
  
  Limfosit
- D.
  
  Sel darah putih
- E.
  
  Fagosit
Correct Answer(s)
C. Limfosit
D. Sel darah putih

Explanation
The correct answer is lymphocytes and white blood cells. Lymphocytes are a type of white blood cell that play a key role in adaptive immunity. They are responsible for recognizing and targeting specific pathogens or foreign substances in the body. This is different from innate immunity, which includes physical barriers like the skin and mucous membranes, as well as non-specific immune cells like phagocytes. Therefore, lymphocytes and white blood cells are considered part of the adaptive immune system.

- D.
  
  Sel T pembantu
- E.
  
  Sel B
Correct Answer
E. Sel B

Explanation
The correct answer is "Sel B". This is because Sel B refers to B cells, which are a type of white blood cell that is responsible for producing antibodies and is involved in the immune response. In the context of the given question, it is mentioned that the cells are undergoing aging in the bone marrow, and B cells are known to be produced in the bone marrow. Therefore, it can be inferred that the correct answer is Sel B.

Imunitas terdiri dari dua jenis yaitu imunitas aktif dan pasif. imunisasi yang dilakukan dengan cara menyuntikan antibodi dari hewan yang telah disuntik dengan antigen. apakah benar pernyataan tersebut merupakan pengertian imunisasi aktif?
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement is false because the given explanation describes passive immunity, not active immunity. Active immunity occurs when the body produces its own antibodies in response to exposure to an antigen, such as through vaccination. Passive immunity, on the other hand, involves the transfer of ready-made antibodies from another source, such as from an animal that has been injected with the antigen.

Berikut adalah sel yang mampu membunuh sel-sel kanker adalah
- A.
  
  Makrofag
- B.
  
  Sel natural kiler
- C.
  
  Neutrofil
- D.
  
  Eosinofil
- E.
  
  Limfosit B
Correct Answer
B. Sel natural kiler

Explanation
Natural killer cells (sel natural kiler) are a type of white blood cell that plays a crucial role in the immune system's defense against cancer cells. These cells are able to recognize and kill cancer cells by releasing toxic substances that induce apoptosis, or programmed cell death, in the cancer cells. Natural killer cells are part of the innate immune system and are particularly effective in targeting and eliminating cancer cells that have lost their ability to be recognized by other immune cells. Therefore, natural killer cells are an important component in the body's natural defense against cancer.

- A.
  
  Mengubah gula darah (glukosa) menjadi gula otot (glikogen) di hati
- B.

- E.
  
  Untuk mensekresikan insulin.
Correct Answer
B. Membentuk hormon thymosin yang berperan dalam sistem imun (kekebalan)

Explanation
The correct answer is that the thymus gland forms the hormone thymosin, which plays a role in the immune system. Thymosin is responsible for the maturation and differentiation of T-cells, which are crucial for the body's immune response. By producing thymosin, the thymus gland helps regulate and support the immune system, making it an important component of the body's defense against infections and diseases.

Sel yang berfungsi menyimpan informasi antigen adalah...

Correct Answer
sel limfosit B-memori

Explanation
The correct answer is "sel limfosit B-memori." Sel limfosit B-memori berfungsi sebagai sel yang menyimpan informasi antigen. Ketika tubuh terpapar kembali pada antigen yang sama, sel limfosit B-memori akan mengaktifkan produksi antibodi dengan cepat untuk melawan antigen tersebut. Sel ini penting dalam respons imun yang cepat dan efektif terhadap infeksi yang sudah pernah dialami sebelumnya.
