Which of the following would decrease body temperature
What activity would decrease body temperature?
Evaporation of water from your skin if it is wet (sweating). If your clothing is wet, you will also lose some body heat through evaporation and through respiration (breathing) when the body temperature is higher than 99°F (37°C). During intense exercise, the body loses 85% of its heat through sweating.
What controls temperature in the body quizlet?
The hypothalamus serves as the thermostat of our body. It regulates body temperature by initiating heat promoting or heat loss mechanisms based on feedback it gets from —— located in skin and in itself.
Which brain region is the main integrating center for thermoregulation?
The hypothalamus is the coordinating or central integration center for thermoregulation.
Which of these happens during the Postabsorptive state?
Glucagon raises the blood glucose level and is the key hormone used to handle the postabsorptive state. Which of these happens during the postabsorptive state? … Blood glucose levels are maintained within an adequate range.
How does hypothalamus regulate body temperature?
When your hypothalamus senses that you’re too hot, it sends signals to your sweat glands to make you sweat and cool you off. When the hypothalamus senses that you’re too cold, it sends signals to your muscles that make your shiver and create warmth. This is called maintaining homeostasis.
Where is the body’s thermostat found?
hypothalamus
In a human, a tiny part of the brain called the hypothalamus, located behind the eyes, serves as the thermostat. It can warm the body by causing it to shiver and cool the body by causing it to perspire. The hypothalamus also regulates hunger, thirst, relationship drive and other body activities.
What happens during the postabsorptive state quizlet?
During the postabsorptive state tissues other than the brain utilize fatty acids for energy, and the liver produces glucose by breaking down glycogen to glucose and converting other substrates to glucose via gluconeogenesis. The adipose tissue breaks down triglycerides to glycerol and fatty acids.
What happens during gluconeogenesis quizlet?
Gluconeogenesis is an protein process, which occurs mainly in the liver, that results in the synthesis of glucose molecules from non-glucose precursors (i.e. Lactate, & Glucogenic Amino Acids, Glycerol & Propionyl CoA). … The hormones that regulate gluconeogenesis are insulin, glucagon, catecholamines and cortisol.
What happens to glucose during the postabsorptive state quizlet?
What happens to glucose during the postabsorptive state? Glucose is converted to fat for storage. Glucose is stored as glycogen and is the primary energy source for all body cells. Glucose is stored as glycogen and spared for use by the nervous system.
What is the major challenge during the postabsorptive state?
sustains a normal blood glucose level is the major challenge during the postabsorptive state. when blood glucose levels drop after a meal, the hormones glucagon and cortisol are released.
Which of the following is not observed during the postabsorptive state?
The correct answer is b). Lipogenesis does not occur during the postabsorptive state. It occurs during the absorptive state. Instead, the breakdown of lipid stores occurs during the postabsorptive state.
What is the primary hormone of the postabsorptive state?
(4). Hormones: Postabsorptive state is largely caused by lack of insulin; also utilizes glucagon, but stress hormones (cortisol and epinephrine) can fill in for glucagon. Glucagon mainly affects liver.
Which of the following helps the core temperature to increase?
Which of the following helps the core temperature to increase? Increase in cellular respiration, Constriction of blood vessels of the skin, Shivering, Thyroid hormone induced increase in metabolic rate.
What causes lipolysis?
Lipolysis is triggered by the activation of adenyl cyclase, which converts adenosine triphosphate (ATP) into cyclic adenosine monophosphate (cAMP). Catecholamines, acting via beta-adrenergic receptors (βADRs), stimulate adenyl cyclase but this action is counteracted by activation of alpha-adrenergic receptor (αADR).
How is the postabsorptive state controlled and initiated?
The postabsorptive state is controlled by the interaction of the sympathetic nervous system and several hormones, especially glucagon. The trigger for initiating postabsorptive events is damping of insulin release, which occurs as blood glucose levels begin to drop.
What causes low core temperature?
Studies show that core body temperature decreases with age. Hypothyroidism, or an underactive thyroid, can also slow down metabolism, which can lead to a drop in body temperature. If your core body temperature dips down to 95 F (35 C) or lower, that’s considered hypothermia.
What is the core body temperature?
Core temperature (Tc), also referred to as core body temperature, is the temperature of the internal organs, such as the liver, located deep within the body. The human body maintains its core temperature within a very narrow range of 36.5-38.5 ℃ [97.7-101.3 °F].
What happens when your core temperature drops?
When your body temperature drops, your heart, nervous system and other organs can’t work normally. Left untreated, hypothermia can lead to complete failure of your heart and respiratory system and eventually to death. Hypothermia is often caused by exposure to cold weather or immersion in cold water.
