Final answer:
The integumentary system consists of the skin, hair, nails, and sweat glands, all of which contribute to protecting the body and maintaining homeostasis. Muscles and arteries are not part of this system.
Step-by-step explanation:
Components of the Integumentary System
The integumentary system is comprised of several components that work together to protect the body and maintain homeostasis. These components include skin, hair, and nails, which are all visible parts of the system. Hair and nails are composed of a tough protein called keratin, which provides durability and strength. Additionally, the integumentary system incorporates sweat glands that help regulate body temperature and expel waste products. While muscles and arteries are essential to the body's overall function, they are not part of the integumentary system; instead, they belong to the muscular and cardiovascular systems, respectively.
