Please construct a model to show that the digestive, respiratory, and circulatory systems work together to supply the body cells with the glucose and oxygen needed for aerobic cellular respiration. Feel free to use words, diagrams, arrows, flowcharts, etc. to get your ideas across. Make sure you include the following information: Digestion of starch into glucose and the location(s) of digestion. Absorption of glucose into the blood and the location of absorption. Blood transporting glucose from the absorption site to the tissues. Glucose entering the tissue cells from the blood. O2 entering the blood in the lungs and the specific location of entrance in the lungs. Blood transporting O2 from the lungs into the tissues. O2 enters the tissues from the blood.
Draw a negative feedback loop for maintaining homeostasis for thermoregulation where your body temperature is above the set point. In your drawing, include the stimulus, sensor, integrator, effector, and the arrows between the components to indicate how they all relate (be sure to indicate what each of these components are in your body, for example, what is your integrator). Further, answer the following two questions. First, what might be different between the response of an endothermic and an ectothermic animal in maintaining homeostasis? Second, describe what a negative feedback loop is and how it pertains to homeostasis.
You are designing an experiment to determine if you can make desert kangaroo rats active at noon. At noon the ground and air are warmer than the internal temperature of the rats. You decide to provide the kangaroo rats with enough water to ensure they can maintain body temperature homeostasis. Based on a simplified model, you determine that at noon, kangaroo rats: - Absorb 8 watts of radiation - Generate 1 watt of metabolic heat - Re-radiate 1 watt - Exchange a total of 2 watts with the surrounding desert ground and air via conduction - Exchange 4 watts through convective processes The kangaroo rat is not in energy balance. Since kangaroo rats lose 1 watt through latent heat (i.e. evaporative cooling) with each 2 ml of water consumed, how much water would you need to provide the kangaroo rat so that it can reach homeostasis? 04 8.

Fill in the blanks using the words provided, each word will only be used onceCellular respiration, energy, ATP, Glucose, Oxygen, Chemical, stored, heat. Directions: Complete the paragraph below to explain why your body gets warm during a workout. Using the words above When you workout, your cells need ____ for muscle contraction. In order to get this, your body will carry out a process called ____. During this process, _____ (from food) is broken down in the presence of _____ to make the usable form of energy for cells, called ______. This process converts ______ energy from the bonds of food molecules into energy that is _____ (potential energy) in ATP molecules. The process also releases _____ (thermal) energy, which is why you feel warm. Your body carries out this amazing process to fuel your workouts!
Some animals adjust their temperature by absorbing heat from their environment. These ectotherms ("cold blooded"), such as a snake or turtle, control temperature by moving to the sun or into the shade. As a result, their temperature fluctuates considerably through the day and night. Other animals generate heat internally. These endotherms (mammals and birds) burn fat and sugar to convert them to heat and so stabilize their body temperatures.

What is thermoregulation and why is it necessary for the human body to function properly? List two physiological responses the human body takes to when its core temperature gets too high. Briefly explain how each works to reduce core temperature. Explain why one of these responses will not work if the air temperature is extremely high. Explain why one of these responses will not work if the relative humidity is extremely high.

Skeletal muscles account for approximately 43% of the typical body mass. At rest, they use about 18% of the BMR. Of the total energy burned by the skeletal muscle, only 25% is used for work, and this is the muscular efficiency. What happens to the remaining 75% of energy? Choose the best answer. It is reabsorbed and stored for later use. It is transferred as electrical energy from the muscle to muscle. It is converted to heat to warm the body. It is used to make more ATP.
An average adult cheetah has a metabolic mass of 44,010 grams and a resting metabolic rate of 61.77 joules per second. Based on these data, would you characterize the cheetah as an ectotherm or endotherm? Support your answer with evidence from the graph.
You are designing an experiment to determine if you can make desert kangaroo rats active at noon. At noon the ground and air are warmer than the internal temperature of the rats. You decide to provide the kangaroo rats with enough water to ensure they can maintain body temperature homeostasis. Based on a simplified model, you determine that at noon, kangaroo rats: - Gain 8 watts of heat from radiation and 1 watt of heat from metabolism - Lose 1 watt of heat by re-radiation - Gain 6 watts of heat from the surrounding desert ground and air via conduction and convection The kangaroo rat is not in energy balance. Since kangaroo rats lose 1 watt through latent heat (i.e. evaporative cooling) with each 2 ml of water consumed, how much water would you need to provide the kangaroo rat so that it can reach homeostasis? 4 8. 12 24 28 O 32
When you jog, most of the food energy you burn above your basal metabolic rate (BMR) ends up as internal energy that would raise your body temperature if it were not eliminated. The evaporation of perspiration is the primary mechanism for eliminating this energy. Determine the amount of water you lose to evaporation when running for 32 minutes at a rate that uses 400 kcal/h above your BMR. (That amount is often considered to be the "maximum fat-burning" energy output. The latent heat of vaporization of water at room temperature is 2.5 106 J/kg.)The metabolism of 1 gram of fat generates approximately 8.65 kcal of energy and produces approximately 1 gram of water. (The hydrogen atoms in the fat molecule are transferred to oxygen to form water.) What fraction of your need for water will be provided by fat metabolism?
Research the behaviours of a specific ectothermic animal. How do specific behaviours allow for the animal to control its body temperature in cool and hot conditions? How do specific parts of the animal’s anatomy help with thermoregulation? Use a feedback diagram to show how this animal uses thermoregulation in one of these conditions: ectotherm in cool conditions ectotherm in hot conditions Be sure to use ⊕ and ⊝ symbols in the feedback diagram to add important details.
