QuestionAnswer
Why does the Conditions in our body matter?-Makes sure the Metabolic Reactions can that keep you Alive keep Going in a stable Way. -Very dangerous if balance is Broken
What are 3 Things the Body needs to keep Constant?-Blood Sugar Concentration [Amount of Glucose] Make sure the balance of glucose is not too High or Low -Water content: Balancing the Water inside you -Body Temperature Balancing how hot you are inside
Where is the Body Temperature controlled?-Hypothalamus [Brain]
Why does the Body Temperature matter?-Enzymes work best at around 37 degrees. -If the Temperature goes lower, The Speed will be Slower -If the Temperature goes High, The Enzymes may Denature, which would Dramatically slow the Reaction down
How can the Hypothalamus detect the Temperature? What would it do if so?-Contains Receptors that can pick up the Blood Temperature in Brain -Gains information from the Skin about External Temperatures -A response is sent into the Dermis [Deep layer of Skin] if a Change happens
What happens when your too Hot?-The Erector Muscles relax = Hairs lie down -Sweat [Water + Salt] is made and Released. When this Sweat evaporates, it takes Energy from the Skin, to the Environment -Blood Vessels Widen [Vasodilation] This allows More Blood near the Surface, so More Energy can be Transferred [Cooling you down]
What happens when your too Cold?-Erector Muscles Contract -- Hairs stand up. This can trap Insulating Layer of Air, warming you up -Little to None Sweat is made -Blood vessels Contract [Vasoconstriction] meaning Less blood can flow near the Surface = Less energy Transferred -Shivering [Done by contraction of Muscles] happens. This needs Respiration to happen which makes Energy to heat the Body
