Answer:

When Steve cut his hand, his Epidermis/skin line of defense was broken.

Explanation:

The epidermis is the most superficial layer of the skin, in contact with the environment. It is formed by stratified squamous and keratinized epithelial tissue. Its name derives from the Greek words epi, which means above and dermis, which means skin. So, it means above the skin.

The functions of the epidermis are:

  • Serve as a protective barrier for the organism;
  • Absorption of ultraviolet rays from solar radiation;
  • Avoid water loss;
  • Promote the feeling of touch.

When Steve cut his hand, he injured his epidermis, and broke through that protective barrier. This opened up an opportunity for microorganisms to infect their injury.
