give two important function of papillary region of dermis
Answers
Explanation:
The papillary layer provides the layer above it, the epidermis, with nutrients to produce skin cells called keratinocytes. It also helps regulate the temperature of our skin and thus the body as a whole.
Both the nutrient supply and temperature regulation occur thanks to an extensive network of blood vessels in this layer. These blood vessels also help remove cellular waste products that would otherwise kill the skin cells if they were allowed to accumulate.
The pink tint to the skin of light-skinned individuals is due to the blood vessels found here. In fact, when you blush, it is the dilation of these blood vessels that causes you to turn red. The uneven projections found in this layer, called dermal papillae, also form people’s fingerprints and give this layer its name.
