Match each accessory structure with its protective function.

Options

  • ARegulation of body temperature
  • BHair and hair follicles
  • CProtection of heavily used, exposed surfaces
  • DNails
  • ERemoval of bacterial waste
  • FRemoval of waste and regulation of temperature
  • GSudoriferous gland

Answer

Hair helps regulate body temperature, nails protect our fingers and toes, and sudoriferous glands remove waste and regulate body temperature. Each structure plays a critical role in the body's defenses and overall function.

Explanation

Accessory structures in the human body, including hair, nails, and glands, each serve specific protective functions that contribute to overall health and well-being. Hair and Hair Follicles (A): Hair helps regulate body temperature by trapping a layer of warm air close to the skin. On the scalp, hair acts as insulation and reduces heat loss, while on the body it can help keep us warmer in cooler environments. Nails (C): Nails protect the tips of our fingers and toes, which are often exposed to mechanical injuries. Their hard, keratinized structure prevents damage from impacts and helps in tasks requiring precision, like picking up small objects. Sudoriferous Gland (G): Also known as sweat glands, they have dual functions: they help remove waste products (like urea and salts) from the body as sweat and also play a crucial role in regulating body temperature through evaporation. When the body overheats, these glands produce sweat, which cools the skin as it evaporates. In summary, hair and hair follicles help manage body heat, nails provide protection to extremities, and sudoriferous glands assist in waste removal and temperature control. Understanding these functions is essential in the study of the integumentary system and its role in maintaining homeostasis.
