Skin, hair, nails, and glands

Explanation:

The integumentary system is an organ system. It consists of skin, hair, feathers, scales, hooves, exocrine glands and nails. These structures provides the external protection to the body from different types of damage like loss of water, injury and invasion of pathogens.  

The skin is a thick outer cover of the entire body. It protects the body from incident UV rays, chemicals, physical damage and diseases.

The nails and hair are the extensions from the skin. They are composed of hard keratin material. They also provide protection against unfavorable external environmental conditions.

The exogenous glands are the glands which are present over the superficial tissues. These produce secretions which protects the entry of microbes inside the body.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
