Termini in questo insieme (12)

  • Which hormone determines basal metabolic rate at rest?

    Thyroid hormone primarily determines the basal metabolic rate at rest.

  • Which hormone determines metabolism at rest while feeding?

    Insulin regulates metabolism during rest while feeding by promoting glucose uptake and storage.

  • Which hormones control metabolic rate during exercise?

    Adrenaline (epinephrine) and glucagon increase metabolic rate during exercise.

  • What are the three main water-regulating hormones?

    Antidiuretic hormone (ADH), aldosterone, and atrial natriuretic peptide (ANP) regulate water balance.

  • What are baseline levels of ADH and aldosterone?

    At baseline, ADH and aldosterone levels are low to maintain normal water and salt balance.

  • How does decreasing plasma volume affect ADH and aldosterone?

    Decreasing plasma volume increases secretion of ADH and aldosterone to conserve water and sodium.

  • How does increasing plasma volume affect ADH, aldosterone, and ANP?

    Increasing plasma volume decreases ADH and aldosterone, and increases ANP to promote water and salt excretion.

  • What initiates the stress response in the endocrine system?

    The sympathetic nervous system initiates the stress response.

  • Which hormone is secreted for short-term effects during stress?

    Growth hormone (GH) is secreted for short-term effects during stress.

  • What role does ACTH play in the stress response?

    ACTH stimulates secretion of aldosterone and cortisol during stress.

  • What hormone does the pancreas secrete during stress and why?

    The pancreas secretes glucagon to increase blood glucose for energy during stress.

  • What is the combined effect of hormones secreted during stress?

    They release fuel by increasing blood glucose and fatty acids to provide energy.
