Phagocytes
- C.
Macrophages
Correct Answer
C. MacrophagesExplanation
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.Rate this question:

What is the best medicine?

Laughter
- B.
Smiling
- C.
Medicine
Correct Answer
A. LaughterExplanation
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.Rate this question:

B-Cell
- B.
Lymphocytes

Granulocytes
Correct Answer
B. LymphocytesExplanation
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.Rate this question:
