Which of the following is an example of homeostasis? Choose all answers that are correct as there may be more than one correct answer. Show answer choices The body shivering when outside in the cold. The release of insulin after a meal to encourage your body to absorb the sugar from your blood, thus lowering your blood sugar. Producing sweat when outside on a hot day that can evaporate into the air. Breathing faster while exercising to add more oxygen to the blood and remove excess carbon dioxide from the blood. Stretch receptors in your blood vessels detect when blood pressure is high and send signals to increase the diameter of your blood vessels and reduce the output from the heart to lower your blood pressure.

Riding a bicycle requires additional energy from leg muscles. Which of the following conditions may result from this activity, and which response helps restore the body to its normal condition? * decreased oxygen can be replaced by digesting an apple. increased carbon dioxide in the blood can be removed by breathing faster. increased sugars in the bloodstream can be diluted by drinking water. increased salt wastes can be removed by the heart. No answer
Which of the following best describes an example of negative feedback? The body starts shivering to generate heat when you detect you are too warm. The feeling of hunger after you've just had a big meal. The increase in breathing rate when the body detects you are low on oxygen and high on CO2. A decreased heart rate in response aerobic exercise. The body sweating when the temperature gets too cold.
Which of the following is maintained at a set point and is an example of homeostasis? Temperature Blood glucose level Blood pH all of the above
Which of the following responses is an effector activated by the hypothalamus when the body temperature is lower than the set point? skin blood vessels dilate skeletal muscles contract move to a warmer location or put on a sweater weat glands initiate sweating
During intense exercises and when muscles are working harder, our cells metabolize glucose rapidly resulting to oxygen molecules being quickly consumed. Which of the following becomes the human body's coping mechanism in response to limited oxygen supply? faster breathing and lower blood circulation slower breathing and faster blood circulation faster breathing and faster blood circulation slower breathing and slower blood circulation
Which of the following would help increase an endotherm's body temperature? Select ALL that apply. shivering blood vessels narrowing sweating blood vessels widening
Which of the following is an example positive feedback? contractions in childbirth blood glucose body temperature body fluid pH
Body temperature is homeostatically regulated around a set point. Given your knowledge of negative feedback and homeostatic control systems, predict whether narrowing or widening of the blood vessels of the skin will occur when a person exercises strenuously. (Hints: Muscle contraction generates heat. Narrowing of the vessels supplying an organ decreases blood flow through the organ, whereas vessel widening increases blood flow through the organ. The more warm blood flowing through the skin, the greater is the loss
Which of the following would help increase an endotherm's body temperature? Select all that apply. sweating A blood vessels narrowing O blood vessels widening shivering
The feedback loop shown below is an example of negative feedback that uses the narrowing and widening of blood vessels in the skin to regulate body temperature. DIRECTIONS: Label the diagram using the words or phrases from the word bank. Then answer the questions that follow. body temperature falls body temperature rises normal body temperature vasoconstriction vasodilation Feedback: Feedback: Response: ACY MENT CHA RICH OF EATIO Response: EX Stimulus: Increase in Body Temperature Stimulus: Decrease in Body Temperature
Imagine you are sick and you have fever. Sensors on the skin and brain detect this and communicate with the temperature regulatory center in the brain which then sends out a command to the sweat glands of your body as a result of which you start sweating and in about 15 mins your body temperature comes back to normal for the time being. This this feedback loop, identify the following: sensors control center effector stimulus response
