Unit 1: Wellness and HomeostasisTopic #1: Health vs. WellnessObjectives: Describe the difference between health and wellness Give examples of factors that affect a persons physical, emotional, spiritual, interpersonal, environmental, and intellectual wellness.What does wellness look like?

Health Vs. WellnessHealthWellnessThe physical well-being of an individualA multi-dimensional interrelationship between the following aspects of life:1) Physical2) Emotional3) Spiritual4) Intellectual5) Interpersonal (social)6) EnvironmentalPhysical WellnessIncludes health, eating well, exercise, and healthy lifestyle choices.

4) Eat breakfast - it's the most important meal of the day

5) Eat a variety of healthy foods

Steps for Improving Physical Wellness6) Practice safe sex

7) See a doctor for regularcheckups

Steps for Improving Emotional Wellness1) Spend time with friends & family discussing personal concerns

Steps for Improving Environmental WellnessRecycleWalk to school or carpoolKeep your binders organizedDont leave the water running & turn out the lights!

Wellness Artefact #1 (10 Marks)Fill in the survey to help reflect on your personal wellness. Think about how you can improve areas in your life to optimize your personal wellness.

After you have finished, reflect about how your personal wellness affects your family, your friends, your school/community, and your environment.Wellness & HomeostasisTopic #3: Living Things Adjust to their SurroundingsObjectives: Define stimulus, response, homeostasis, dynamic equilibrium, and negative feedback Give examples of types of homeostatic mechanisms Give examples of a negative feedback cycleEnvironmental FactorsOrganisms live in a constant interface with their surroundings, or environment. This includes:1) Air2) Water3) Weather4) Temperature5) Other organisms in the area

Adjusting to SurroundingsAnything in an organisms external or internal environment that causes the organism to react is a stimulus.A reaction to a stimulus is a response.

Stimulus touching a hot panResponse dropping the panHomeostasis: response to stimuli

The ability to respond to stimuli in the environment is an important characteristic of living things.Homeostasis is regulation of an organisms internal environment to maintain conditions suitable for its survivalE.g. Organisms must make constant adjustments to maintain the proper internal temperatureTypes of Homeostatic MechanismsTo function properly, homeostatic mechanisms must allow the body to:1) Regulate respiratory gases

2) Maintain Water and Salt Balance

3) Regulate Energy & Nutrient Supply

4) Maintain Constant Body Temperature

5) Protect Against Pathogens

6) Make Repairs when Injured

Dynamic EquilibriumBecause the external environment is constantly changing and homeostatic reactions respond to the change and bring the body back to a given set point, it is often referred to as a dynamic equilibriumDynamic equilibrium is a condition that remains stable within fluctuating limitsNegative FeedbackThink of your body like a thermostatWhen the room temperature goes down,the thermostat tells the heater to turn on.This heats up the room to normal temperature.

A Negative Feedback cycle is an internal feedback mechanism in which a substance is fed back to inhibit the original signal and reduce production of a substance

Body Regulation3 Feedback Cycles that help the body regulate homeostasis are:1) Thermoregulation2) Osmoregulation3) Waste Management

ThermoregulationThermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the external temperature is different.If the environment is colder than the bodys dynamic equilibrium, and the body systems are unable to maintain normal temperature, hypothermia resultsIf the environment is warmer than the bodys dynamic equilibrium and the body systems are unable to maintain normal temperature, hyperthermia results OsmoregulationOsmoregulation is the regulation of water and salt balance in the body

Waste ManagementWaste Management is the regulation of wastes within the body. Examples of waste:1) Carbon Dioxide2) Urea3) Indigestible materials
