Dermis . Structure: Deep part of skin connective tissue composed of two layers. Function: Is responsible for the structural strength and flexibility of the skin the epidermis exchanges gases, nutrients, and waste products with blood vessels in the dermis . Papillary layer.
The subcutaneous tissue is called the superficial fascia, or ? hypodermis. Physiologists believe that some sweat glands produce aromatic, organic molecules, called pheromones, that may serve as sex attractants. The type of sweat gland (of the two discussed in this exercise) most likely to produce pheromones is ?, State the relative location, tissue type, and function of the hypodermis.

What is the relative strength of epidermis and dermis in the skin? Skin Human skin, the largest organ of the body, is composed of different layers each serving a different function.
The papillary dermis is the upper portion beneath the epidermis , characterised by thin haphazardly arranged collagen fibres, thin elastic fibres and ground substance. The lower portion is the reticular dermis , composed of coarse elastic fibres and thick collagen bundles parallel to the skin surface. The dermis is full of double rows of peg-like formations called papillae under the basement membrane zone.
Dermis . The dermis acts as a supporting structure for the epidermis and contains proteins such as collagen and elastin. These provide the skin with strength , the ability to stretch and the ability to return to its original shape. In older people, these proteins start to decrease, making their skin more delicate.
