papillary layer
The Papillary Layer which is a part of the Dermis
The epidermis
The epidermis, or the outermost layer, contains no blood vessels.
It produces the ridges that make fingerprintsdermal papillae.
Blood vessels are surrounded by very small circular muscles which contract and relax to allow blood vessels to constrict and dilate. The vessels also contain elastin which allows them to stretch.
The two layers of the dermis are the papillary dermis, which is the upper layer closest to the epidermis and contains blood vessels and sensory receptors, and the reticular dermis, which is the deeper layer made up of dense connective tissue, collagen fibers, and sweat glands.
The papillary layer of the skin is made up of loose connective tissue. This type of connective tissue is less dense and contains collagen and elastic fibers that help support the overlying epidermis, as well as blood vessels and nerves.
The papillary layer of the skin is one of two layers of the dermis.
Endothelium, which is the innermost layer of all blood vessels.

The layer of the skin that contains blood vessels is the dermis. Blood vessels in the dermis help nourish the skin cells and regulate body temperature.
