The integumentary system helps regulate body temperature through its tight association with the sympathetic nervous system, the division of the nervous system involved in our fight-or-flight responses. Finally, while technically not a thermoregulatory mechanism, the fat associated with our skin does help insulate our body and therefore increases body temperature as a result. The integument as anorgan, and is an alternative name forskin. The integumentary system helps regulate body temperature through its tight association with the sympathetic nervous system, the division of the nervous system involved in our fight-or-flight responses. Diffusion provides nourishment and waste removal from the cells of the dermis, as well as for the cells of the epidermis. The stimulus for the secretion of apocrine sweat glands is adrenaline, which is a hormone carried in the blood. This system protects the body and inner organs from harmful outer agents. It has a variety of additional functions; it may serve to waterproof, and protect the deeper tissues, excrete wastes, and regulate body temperature, and is the attachment site for sensory receptors to detect pain, sensation, pressure, and temperature. The main function of the integumentary system is to protect the internal organs from any kind of damage. The skin assists in homeostasis (keeping different aspects of the body constant, e.g., temperature). Its main function is to act as a barrier to protect the body from the outside world. Protection – protects against water loss/gain, chemicals, and mechanical injury – immune system protects against pathogens and other microorganisms i. Keratinized stratified epi. Radiation, in this case, refers to thermal radiation, which is the process of transferring heat through space via electromagnetic waves. These help move our body parts away from potential sources of damage, like hot stoves, when they sense danger, thereby protecting our body from great harm. Integumentary System. The integumentary system of vertebrates is genuinely a ‘jack-of-all-trades’ since it performs several essential functions, some of which are: Protection. The sympathetic nervous system is continuously monitoring body temperature and initiating appropriate motor responses. Left unregulated, this would kill a person quite quickly. The sympathetic nervous system is continuously monitoring body temperature and initiating appropriate motor responses. Together they provide a wide range of mechanical sensitivity that enables fine motor control. UNIT 2 INTEGUMENTARY SYSTEM REVIEW SHEET ANSWERS 1. The integumentary system helps regulate body temperature through its tight association with the sympathetic nervous system, the division of the nervous system involved in our fight-or-flight responses. This makes the hairs stand on end, which acts as an insulating layer, trapping heat. Protection: The integumentary system's main function is to protect your body from injury and pathogens. Write. UNIT 2 INTEGUMENTARY SYSTEM REVIEW SHEET ANSWERS 1. Hair Shaft Epidermis. The skin is composed of tough skin cells as well as a tough protein called keratin that guard tissues, organs, and structures underneath the skin against physical damage from minor cuts, scratches, and abrasions. (adsbygoogle = window.adsbygoogle || []).push({}); The skin provides an overlaying protective barrier from the environment and pathogens while contributing to the adaptive immune system. Physical barrier from environment. it’s really windy), and the smaller the distance between the skin surface and the blood vessels, the greater the loss of heat from our body via convection. Melanin Subcutaneous. Integumentary System Function. A main function of the integumentary system is _____.
