Which of the following statements is true concerning feedback mechanisms? Which of the following statements is true concerning feedback mechanisms? Negative feedback mechanisms work to prevent sudden severe changes within the body. Positive feedback mechanisms always result in excessive damage to the host. Blood glucose levels are regulated by positive feedback mechanisms. Negative feedback mechanisms tend to increase the original stimulus.

Which of these are examples of negative feedback?Question 8Select one or more:a.The use of sweating and shivering to bring body temperature back to the correct set point (37°C)b.Platelets producing chemical signals to attract more platelets to a wound during blood clotting.c.Regulation of blood glucose levels by production of insulin and glucagon.d.Regulation of blood salinity by production of ADH to adjust level of water retention by kidneys.e.Oxytocin stimulation of uterine contractions during childbirth..

Which is an example of negative feedback?Question 1Select one:a.lowering of blood glucose after a mealb.blood clotting after an injury.c.lactation during nursingd.uterine contractions during labore.all of the above

Which of the following is the best description of the homeostatic mechanism of negative feedback?Adjustment made by the body to return itself to normal after detecting a changeAdjustment made by the body to decrease the rate of metabolismAdjustment made by the body to increase the rate of metabolismThe negative thoughts that occur when the body is in fight or flight mode2What is the role of the pituitary gland in regulating metabolic rate? It detects the levels of glucose in the bloodIt releases thyroxineIt releases thyroid stimulating hormoneIt controls the amount of oxygen entering the body3What happens when the amount of thyroid stimulating hormone released from the pituitary gland increases? More thyroxine is released from the thyroid, metabolic rate increasesLess thyroxine is released from the thyroid, metabolic rate decreasesMore thyroxine is released from the thyroid, metabolic rate decreasesLess thyroxine is released from the thyroid, metabolic rate increases4Which gland is located at the top of your kidneys?Adrenal glandsPituitary glandSweat glandThyroid gland5Which of the following is not a ‘flight or fight’ response caused by the release of adrenalin? Increased heart rate and breathingBreakdown of glycogen reserves to produce glucoseBlood redirected from skeletal muscles to digestive systemDilation of pupils6Which of the following hormones is not controlled by a negative feedback mechanism?AdrenalinADHInsulinThyroxine
