North-burn 100 homeostasis
Hyporthermia
must be warmed somehow
Shiver
blood vessles contract
Goose bumbs --> allow hair to be taller off skin
Hair on arms stick up to create barrier for skin
When the body loses heat faster than it can produce heat, causing a dangerously low body temperature.
Oxygen demand
Definition: Oxygen demand is an environmental chemistry term that may refer to: Biochemical oxygen demand (BOD), the amount of oxygen needed by organisms to break down organic material present in a water sample.
Increase in carbon dioxide levels. This is unhealthy and un natural for the human body
The runner will lack energy to finish the race
Oxygen is required for ATP
If a runner fails to inhale enough oxygen it can cause your blood to lack oxygen and your body will start to shut down.
Hyperthermia
Sweat
Increase breathing rate
blood vesses dialate
A dangerously overheated body, usually in response to prolonged hot, humid weather.
Blood glucose levels Definiton: The blood sugar level, blood sugar concentration, or blood glucose level is the concentration of glucose present in the blood of humans and other animals.
eat sugary foods
Keep enough glucose in body to keep functioning and not get tired
energy drinks increase glucose levels --> more energy
Thermoregualtion
Definition: Thermoregulation is a process that allows your body to maintain its core internal temperature. All thermoregulation mechanisms are designed to return your body to homeostasis. This is a state of equilibrium. Healthy internal body temperature falls within a narrow window.
It is extremely important in such an extreme event that is very hard on the human body that a steady thermoregulation is kept. This event is raced in harsh weathers such as strong cold winds and horizontal rain. This can cause the athlete to become extremely cold and hypothermia is a realistic posibility
The northburn 100 is very hard on the body it is an event that is raced in March each year. Autumn in central Otago can either be very warm or very cold it depends on the year. This means an Athlete racing in this race needs to be prepared for any weather condition. The race runs over harsh farm terrain which is known for strong cold winds. Keeping the athletes thermoregulation steady is very important. Wearing clothing such as wool thermals and wind breakers will help keeping the body temperature at 37 degrees. If the weather was very hot making sure the athlete keeps the sun off their face and stays hydrated will help stop the chance of the athlete getting hyperthermia
Osmoregulation
Definition: the maintenance of constant osmotic pressure in the fluids of an organism by the control of water and salt concentrations.
Negative feedback
Negative feedback mechanisms detect departures from a set point norm and act to restore the steady state.
movement away from the steady state is detected and triggers a mechanism to counteract that change
enzymes denature in temperature above 40oc which can results in death
Positive feedback
Positive feedback results in the escelation of a respnse to a stimulus. It causes system instability and is used where a particular outcome or resolution is required.
Labour
Blood clots
fever
Homeostasis
Definition: Homeostasis refers to the (relatively) constant physiological state of the body despite fluctuations in the external environment.
Maintaining Homeostasis
The body's organs work together to maintain homeostasis
