  • <u>Medullary hormones</u>: the epineprhin and the norepineprhin. <u>Five different effects that these hormones produce are:</u> increase heart rate, produce cardiac muscle contraction, elevate blood preasure, increase breathing, dicrease digestive activity, increase metabolic rate.
  • <u>The most important mineralocorticoid secreted by the adrenal cortex: </u>aldosterone.
  • <u>Actions of the aldosterone: 1. </u>Conserves sodioum ions and water in kidneys. 2. Excrete potasium ions 3. Conserves H2O.
