7 Skin layers

1. Epidermis (Outer Layer)

• • The protective outermost layer of the skin.

  • Contains no blood vessels.

  • Primary components:

  • Sweat glands: Regulate temperature and excrete waste.

  2. Dermis (Middle Layer)

  • Thicker layer beneath the epidermis.

  • Contains connective tissues, blood vessels, and nerves.

  • Key components:

  • Fibroblasts: Cells responsible for producing collagen and elastin.

  • Hair follicles: Structures from which hair grows.

  • Lymphatic vessels: Help with immune response and fluid balance.

  3. Hypodermis (Subcutaneous Layer)

  • Deepest layer, consisting of fat and connective tissue.

  • Provides insulation, cushioning, and energy storage.

  • Contains:

  • Blood vessels: Supply nutrients and oxygen to the skin.

  • Adipose tissue: Stores fat for insulation and cushioning.

  These layers work together to protect the body, regulate temperature, and maintain hydration.
