Questions and Answers

1.

What is the immune system's distress signal?
- A.
  
  Lymph Nodes
- B.
  
  Phagocytes
- C.
  
  Macrophages
Correct Answer
C. MacropHages

Explanation
Macrophages are a type of white blood cell that play a crucial role in the immune response. They act as the first line of defense by engulfing and destroying foreign invaders such as bacteria and viruses. Macrophages also release chemical signals called cytokines to alert other immune cells of the presence of pathogens. These cytokines act as distress signals, triggering a cascade of immune responses to eliminate the threat. Therefore, macrophages can be considered as the immune system's distress signal.

The spleen is the "graveyard" for old red blood cells.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The spleen is responsible for removing old and damaged red blood cells from circulation. It acts as a filter, breaking down these cells and recycling their components. This process helps to maintain the overall health and functionality of the blood. Therefore, it can be said that the spleen functions as a "graveyard" for old red blood cells.

What is the best medicine?
- A.
  
  Laughter
- B.
  
  Smiling
- C.
  
  Medicine
Correct Answer
A. Laughter

Explanation
Laughter is considered the best medicine because it has numerous physical and mental health benefits. When we laugh, our body releases endorphins, which are natural painkillers and mood elevators. Laughing also boosts our immune system, reduces stress and anxiety, and improves cardiovascular health. Moreover, laughter promotes social bonding and enhances our overall well-being. Smiling can also have positive effects, but laughter goes beyond just a smile and has more comprehensive benefits. Medicine, on the other hand, refers to specific treatments for illnesses and does not have the same holistic impact on our health.

Natural Killer Cells consult the lymph nodes.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Natural Killer (NK) cells are a type of white blood cell that are part of the innate immune system. They are able to directly kill infected or cancerous cells without prior consultation with the lymph nodes. Therefore, the statement that NK cells consult the lymph nodes is false.

What does dieting do?
- A.
  
  Reduces number of killer cells
- B.
  
  Reduces number of T-Cells
- C.
  
  Harms the spleen
Correct Answer
A. Reduces number of killer cells

Explanation
Dieting reduces the number of killer cells. Killer cells are a type of white blood cell that play a crucial role in the immune system by identifying and destroying infected or abnormal cells in the body. When someone is dieting, they often restrict their calorie intake, which can lead to a decrease in overall immune function. As a result, the number of killer cells may decrease, compromising the body's ability to fight off infections and diseases.

What cell allows us to remember previous invaders and prevents us from getting sick the next time by the same invader?
- A.
  
  B-Cell
- B.
  
  Lymphocytes
- C.
  
  Granulocytes
Correct Answer
B. LympHocytes

Explanation
Lymphocytes are a type of white blood cell that play a crucial role in the immune response. They are responsible for recognizing and remembering specific pathogens or invaders that the body has encountered before. This memory allows lymphocytes to mount a faster and more effective immune response upon subsequent exposure to the same invader, preventing us from getting sick. B-cells, a type of lymphocyte, produce antibodies that specifically target and neutralize pathogens, further enhancing the immune response. Therefore, lymphocytes are the cells that allow us to remember previous invaders and protect us from getting sick again.
