Bleeding involves which types of blood vessels?

• A. Arteries, veins and capillaries
• B. Arteries only
• C. Veins only
• D. Capillaries only

Answer: (A)

Bleeding can involve any blood vessel in the circulatory system—arteries, veins, or capillaries—because an injury can damage vessels of different sizes and pressures. Arterial bleeding occurs under high pressure and typically spurts bright red blood; venous bleeding is usually steadier with darker blood due to the lower pressure in veins; capillary bleeding tends to ooze from small, damaged vessels. Since injuries can disrupt any of these vessels, bleeding can involve all three types. In practice, control bleeding with direct pressure promptly and seek medical help for heavy or persistent bleeding.
