Question

Quizplus · Accepted Answer

Capillaries are the smallest blood vessels in the body and are responsible for the exchange of nutrients, gases, and waste between the blood and tissues. Capillary walls are thin and fragile, making them more prone to damage and bleeding in cases of injury or trauma. The oozing blood from the abrasions on both knees and palms of both hands suggests that capillaries have been damaged, leading to bleeding. Veins and arteries, on the other hand, are larger blood vessels that carry blood to and from the heart, and lymphatic vessels are responsible for the transport of lymphatic fluid and immune cells. None of these vessels are typically associated with minor bleeding from superficial injuries like the one described in this scenario.
