Detailed explanation-1: -The epidermis is the outermost part, made of stratified squamous epithelial tissue. So, are there blood vessels in the epidermis? Nope. It’s epithelium and epithelial tissue is avascular.
Detailed explanation-2: -The Epidermis (thin outer layer of skin) The Epidermis does not contain blood vessels (non-vascular). It contains the pigment melanin which gives skin colour and allows the skin to tan, uneven distribution of melanin causes ‘freckles’. The protein keratin stiffens epidermal tissue to form finger nails.
Detailed explanation-3: -The second layer of the skin (located under the epidermis) is called the dermis; it contains collagen and elastin, blood vessels, lymph vessels, nerve endings, sweat glands, sebaceous (oil) glands, and hair follicles.
