D2 Explain The Concept Of Homeostasis Essay
Unit 5 task 3 (P5 M2 D2) – explain the concept of homeostasis, discuss the probable homeostatic response to changes in the internal environment during exercise, how homeostatic mechanisms control temperature, breathing and heart rate and evaluate the importance of homeostasis in maintaining healthy functioning of the body.
Homeostasis
Homeostasis is the maintenance of a constant internal environment in organisms. It involves volume of blood and tissue fluid within restricted limits, it also maintains chemical makeup of the blood. Autonomic control systems throughout the body maintain temperature and water levels, which are required for cells to function properly. Although homeostasis maintains the internal environment it does not mean that there are …show more content…
Less heat is transported from the core to the surface of the body, maintaining the core temperature. Frostbite can occur causing extremities to turn blue.
Muscles relax causing vasodilation meaning more heat is carried from the core to the surface where it is lost by convection and radiation. Skin turning red is another response to the body becoming hot.
Sweat glands
No sweat produced
The glands release sweat onto the surface of the skin where it then evaporates. Since water has high latent heat of evaporation it also heat in the body to be released.
Erector pili muscle in the skin
Muscles contract raising the hair on the surface of the skin, tapping an insulating layer of still, warm air next to the skin. It is not the most effective method in humans it tend to generally cause goose bumps.
Muscles relax lowering the hairs on the surface of the skin therefore allowing air to circulate over encouraging convection and evaporation.
Skeletal muscles
Shivering which is when the muscles relax and contract repeatedly this generates heat by friction and from metabolic reactions: 60% of increased respiration generates
