Anatomy & Physiology Question #47
Which capillaries nourish the epidermis?
- Subcutaneous tissue.
- Reticular layer of the dermis.
- Papillary layer of the dermis.
The correct answer is D. The epidermis does not contain blood vessels. They do contain blood capillaries in the upper layers of the dermis. This is also known as the papillary layer of the dermis. Diffusion provides nourishment and waste removal from these cells.Subcutaneous tissue, hypodermis, and reticular layer of the dermis are not correct terms for the parts of the epidermis that relate to capillaries.
