Question
Chapter 2, Problem 14WIO
Summary Introduction
To determine:
The regulation of body temperature is essential to survival.
Introduction:
In all living organisms, water is the main source to regulate temperature because it is resistant to temperature change and evaporation. Water helps to remove heat from the body when a person gets sweat that regulates the body temperature. Extreme heat leads to denaturation of proteins.

A fever is an increase in body temperature above normal range. A fever causes metabolic changes that push the person's body temperature even higher. If body temperature rises above 45oc death occur because cellular proteins change shape and metabolism stops. Is a fever of positive or negative feedback system? Explain

- Why is it essential for organisms to maintain a relatively constant body temperature? Describe adaptations that help the organisms cope with changes in environmental temperature.arrow_forwardRead the situation below and draw a diagram or illustration on how a fever happens. When bacteria are destroyed by leuckocytes, pyrogens are released into the blood. Pyrogens reset the body’s thermostat to a higher temperature, resulting in fever. How might pyrogens cause the body temperature to rise? The hypothalamus maintains the set point for body temperature through reflexes that cause vasodilation and sweating when the body is too warm, or vasoconstriction and shivering when the body is too cold. It responds to chemicals from the body. When a bacterium is destroyed by phagocytic leukocytes, chemicals called endogenous pyrogens are released into the blood. These pyrogens circulate to the hypothalamus and reset the thermostat. This allows the body’s temperature to increase in what is commonly called a fever. An increase in body temperature causes iron to be conserved, which reduces a nutrient needed by bacteria. An increase in body heat also increases the activity of the animal’s…arrow_forwardA fever is an increase in body temperature above the normal range.

- Explain the following statement. “All systems of the body contribute to homeostasis.” Use an ANALOGY of DAILY LIFE and give an example of a negative feedback loop.arrow_forwardThe diagram shows an internal feedback mechanism that helps the body maintain homeostasis. Homeostasis in the Body Researchers tested blood sugar levels of 100 volunteers exactly two hours after eating a specific meal. Based on their ages, the volunteers were expected to have a healthy blood sugar level of less than 140 mg/dL. Approximately 10% of the volunteers had blood sugar levels higher than 140 mg/dL. Using the diagram, infer one possible cause for these high blood sugar levels. Raises blood sugar High blood sugar Glycogen Liver Stimulates glycogen breakdown Glucose Glucagon Lowers blood sugar Stimulates glycogen formation Insulin 0000 Tissue cells Stimulates glucose uptake from blood Low blood sugar Promotes insulin release Pancreas Promotes glucagon release The liver was not responsive to the glucagon that was produced. The body did not produce enough insulin to have the expected effect. The pancreas stopped glucagon production. The pancreas produced too much insulin.arrow_forwardPredict what would happen to the metabolic rate of the mouse if you increased the temperature. Predict what would happen to the metabolic rate of the mouse if you decreased the temperature (You can make this prediction with text or with lines on your graph). Support your prediction with evidence about endotherms and ectotherms. (Hint: Think about what happens to your body when you get hot or cold.)arrow_forward
- Show how the nervous system coordinates and regulates feedback mechanism to maintain hemeostasis by creating a graphic organizer. Suppose a girl ate too many sweets such as chocolates. How will the hormones (insulin) from her pancreas help her body cope with a possible blood sugar level rise above normal?arrow_forwardPositive feedback loops are the opposite of negative feedback loops. In a positive feedback loop, any change in the original variable triggers mechanisms that actually push the variable further in the direction of the change. Imagine that body temperature was regulated in this way. Briefly explain what would happen.arrow_forwardAdaptations to regulate internal body temperatures include:arrow_forward
- A high metabolic rate warms the animal from within, and insulation (such as fur and body fat) slows heat loss. Birds for example are warm-blooded animals that have high metabolism. During the winter, how do birds keep their body warm? The answers are found in their parts, their feathers, legs and feet, and their behavior like fluffing, shivering and roosting. How do their feathers, legs and feet help them regulate their body temperature? How do fluffing, shivering and roosting regulate bird's body temperature?arrow_forwardLIST THE MAIN COMPONENTS OF A NEGATIVE FEEDBACK CONTROLSYSTEM.
