Vitamin C contributes to wound healing by increasing which immune cells?

• A. Leukocytes and macrophages
• B. Eosinophils only
• C. Platelets
• D. Red blood cells

Answer: (A)

Vitamin C supports wound healing by boosting white blood cell function, especially the cells that drive early defense and cleanup. It enhances neutrophil activity such as chemotaxis and phagocytosis and also supports macrophage function, helping these cells clear debris and coordinate repair signals. This makes leukocytes, including macrophages, key players in the healing process, which is why the best choice is leukocytes and macrophages. The other options don’t fit because platelets are involved in clotting, red blood cells carry oxygen, and eosinophils are a specific leukocyte subset not the primary target of vitamin C’s wound-healing effects.
