Why is an adequate blood supply important for healing?

• A. It provides hydration to the wound
• B. It delivers oxygen and nutrients
• C. It increases wound temperature
• D. It prevents scarring

Answer: (B)

An adequate blood supply is crucial for wound healing because it delivers oxygen and nutrients to the tissues that are necessary for cellular functions and tissue repair processes. Oxygen is essential for cellular respiration, which generates the energy required for cell growth and regeneration. Nutrients such as vitamins and minerals are also transported via the bloodstream, supporting the synthesis of collagen and other extracellular matrix components that are vital for forming new tissue. Additionally, the blood supply brings immune cells to the site of injury, which helps prevent infection and promotes the healing response. Without sufficient blood flow, these processes are impaired, leading to delayed healing or complications.
