Integumentary Flashcards
What are some examples of intergumentary?
protection, regulation of body temperature and absorption and excretion.
What do changes in temperature and humidity do?
help to regulate body temperature control moisture loss and maintain the balance of fluids.
What does disease do?
works to neutralise aggressors such as bacteria, viruses and pollution and prevent them from entering the body.
What do UV rays do?
over exposure to these harmful rays generate free radicals – aggressive molecules that cause cell damage.
What do pressure blows and abrasion do?
recognises pain and alerts us to danger. It acts as a barrier and shock absorber.
What do chemical substances do?
first line of defence against the aggressive formulas that we may encounter either in the workplace or at home if we use harsh cleansing products or inappropriate skincare.
What temperature is a regular constant?
86.8 degrees celsius.
When metabolic rate increases…
body temperature rises and when decreased body temperature falls.
What is radiation?
heat away from the body.
What is evaporation?
when the body is cooled body heat converts the water in sweat to water vapour.
What is conduction?
when clothes and other objects in direct contact with the skin take up heat.
What is a convection?
air passing over the body raising heat off the surface of the skin, this has a cooling effect.
In relation to heat, what is vasodilation?
arterioles dilate so more blood enters skin capillaries and heat is lost.
In relation to cold, what is vasoconstriction?
– arterioles get smaller to reduce blood going to skin keeping core warm.
What is sweating?
sudorific glands secrete sweat which removes heat when water changes state.
