Homeostasis is a natural phenomenon which is body’s tendency to maintain internal stable and favorable environment against any situation that would tend to disturb its normal condition and function. Such as, If the temperature rises, the body loses heat by sweating or panting, via the latent heat of evaporation. If it falls, this is counteracted by increased metabolic action, by shivering and in fur or feather coated animals, by thickening the coat. Like temperature our body can sense the change in osmolarity and to maintain a stable condition body needs to persist on a certain osmolarity. Secretion of certain hormones can be stimulated by any change in the osmolarity to help maintain a certain level of osmolarity - briefly discuss the mechanism of action and biochemical function of such a hormone.

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
*our body is tightly regulated to maintain an internal (core) temperature of 98.6 degrees F. Your body does not function properly if you get too hot or too cold, partially because protein enzymes get too "stiff" (cold temperatures) or denatured (hot temperatures). If blood temperature rises too high, this is sensed by specialized neurons in the brain. They signal other herve centers, which in turn send signals toʻthe blood vessels of the skin. As these blood vessels dilate, more blood flows close to the body surface and excess heat radiates from the body. If this is not enough to cool the body back to its set point, the brain activates sweating. Evaporation of sweat from the skin has a strong cooling effect, as we feel when we are sweaty and stand in front of a fan. In this example, the brain is a(n): а. гесеptor b. control center nent C. effector eweet alands, are a(n):
Autism is a condition that is generally characterized by difficulties in communicating, understanding abstract concepts, and forming relationships with other people. Recent studies show that children with autism tend to have low levels of oxytocin. Oxytocin nasal spray has been tried as a medical intervention. List two main functions of oxytocin in the body.
If daytime body temperature of some ectotherms were measured, the values would be fairly constant. Provide an explanation for such observations, giving some possible mechanisms that might be involved
What specific evidences can be used 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”.
All else being equal, a warm chameleon sitting on a sunny tree branch will experience a decrease in body temperature due to conduction if: O It changes color, and its new hue is a lighter color, reducing the amount of energy the chameleon absorbs from the sun. A cold breeze moves over the chameleon, transferring heat from the warmer chameleon to the cooler, moving ain. It opens its mnouth, allowing water to evaporate from its tongue and cheeks. The branch is cooler than the chameleon, and heat moves directly from the warmer animal to the cooler branch.
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 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
In this example your body is reacting to you suddenly stepping outside into 30 degree weather after being inside at 20 degrees. match the correct stage with the example of what should be happening to your body • Hot outside air temperature is felt through thermodetectors in your skin and starts to impact how cells, enzymes & body function. •Thermostat is hypothalamus activated cooling mechanisms. • skin blood vessels dilate and sweat glands are activated. •Thermostat is hypothalamus registers internal temperature decrease and is triggered to shut off cooling mechanisms. • internal body temperature remains stable at 37. Homeostasis Imbalance Body reacts Negative feedback correction
During a bacterial infection, the pathogen and the immune system send signals to the hypothalamus suggesting that temperature is set too low. In which of the following ways would the body respond? Sweating Breathing heavily Shivering Laying out splayed on the bed
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.
