Functions of the Integumentary System
The primary functions of integuments include:
- Protection: Integument protects against external strains, infectious pathogens, UV radiation, etc.
- Regulation: Regulation of body temperature is an important aspect of integuments. It maintains the body temperature by sweat production, blood flow regulation, and insulation.
- Sensation: Integuments also function as sensory receptors. They help in detecting touch, temperature, and pain, allowing organisms to interact with their environment.
- Excretion: Integuments facilitate the excretion of waste products via sweat glands. It helps the body maintain homeostasis.
- Respiration: In various organisms, the integument helps in gas exchange i.e. allowing oxygen uptake and carbon dioxide release, especially in aquatic environments.
Integument in Biology
An integument is a layer or coating on the surface of an organism. It may cover the whole organism or parts of it, depending upon its nature and need. Integuments can include skin, hair, membrane, cuticle, etc., based on their function. The integument serves as the primary layer that separates underlying tissues & the external environment. The absence of this layer hinders the organism’s capacity to survive and operate.
This article discusses the definition of the integument, the human integumentary system structure, its functions, how the integumentary system works with other systems, the integuments in different organisms, and common integumentary disorders.
