- With regard to thermoregulation in humans, what could be considered an accurate consequence of the outside temperature dropping below the lower critical temperature? A. The individual will begin to breathe in less oxygen and exhale less carbon dioxide. B. The metabolic needs of the individual will increase if they remain below the lower critical temperature for sufficient time-frames. C. Capillaries (i.e. blood vessels) near the surface of the skin will dilate in order to allow blood to circulate more freely throughout the organism, distributing heat to raise temperature. D. The person's Basal Metabolic Rate will be lowered to match the Standard Metabolic Rate of an ectotherm of comparable size. E. Hormones from the hypothalamus will be released, which lead to the initiation of a positive feedback response that amplifies muscle contraction, leading to shivering.The uncoupling of photon movements results in thermoregulation. Explain and define the terms Brown fat and non shivering thermogenesis as to the production of heat in babies.Thermoregulation is a process used to maintain body temperature within an optimum range. Describe how the human body maintains body temperature in both hot and cold weather ensuring you explain the mechanisms that are involved.
- This is about the application Le Chatelier's Principle to Thermoregulation and Homeostasis within humans. Apply the concept of Le Chatelier’s Principle and discuss how it works:A patient accidentally swallows 4 pills of Ipecac, a known emetic. He then suffers the consequence, with one effect being hypochloremia. His blood gas results show an increased pCO2, increased pH, and increased bicarbonate levels as his body tries to correct the condition. Which of the following is the body's response to the condition stated above and as mirrored by the blood pH and gas analysis? metabolic correction of respiratory alkalosis metabolic correction of respiratory acidosis respiratory correction of metabolic alkalosis respiratory correction of metabolic acidosisUsing a specific evidence of thermoregulation to support the statement that “The importance of the effect of temperature on physiological function is revealed by adaptations to maintain function at different temperatures”. How exactly is thermoregulation involved as an adaptation?
- List and explain two mechanisms the body uses to keep you warm on a 45° day.The following questions apply to this information:A man licks a newt after being dared to do so by his boyfriend. Almost immediately, the man noticed that his lips and tongue felt numb. Within a few minutes, the man began to show a lack of coordination and skeletal muscle control. Within several more minutes, the man experienced difficulty breathing and symptoms of cardiac arrest. Eventually, the man dies. The newt's skin has tetrodotoxin in it. Tetrodotoxin is produced by rough-skinned newts as a form of defense against predation. Tetrodotoxin specifically blocks the sodium pore in voltage-gated sodium channels. It does not affect the gates of a voltage-gated sodium channel. The toxin has no other effects.We will use one bipolar neuron to answer the following questions. This neuron has a resting membrane potential of -65mV. 1) true/false While under the effect of tetrodotoxin, the man's neurons would be able to reach threshold potential at their initial segments. 2) true/false The…Describe thermoregulation in humans (i.e. what happens when body temperature falls or rises beyond the tolerance range?)
