PATHOLOGY

Detailed explanation-1: -The primary function of capillaries is the exchange of materials between the blood and tissue cells.

Detailed explanation-2: -Over time, most of the newly formed capillaries regress, resulting in a final vascular density similar to that of normal skin. Certainly, new capillaries are necessary to bring nutrients, immune cells, and oxygen to healing wounds.

Detailed explanation-3: -Capillary cells have the ability to regenerate from pre-existing blood vessels; this process is called angiogenesis. Angiogenesis occurs in the healthy body for healing wounds, and for restoring blood flow to tissues after injury or trauma.

Detailed explanation-4: -Capillaries are the smallest blood vessels in the body, connecting the smallest arteries to the smallest veins. These vessels are often referred to as the “microcirculation” because they deliver oxygen and nutrients to all cells in the body, and remove carbon dioxide to be eliminated.
