Answer:
- <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.
Explanation:
The epineprhin and norepineprhin are the most important medullary hormons. They are so important because of the functions that they have. They are responsable for the increase of heart rate and if it´s movement, along with digestive and metabolic activity.
Thanks to the aldosterone which is the most important secreted minaralocoricoid, kidneys conserve water and sodium and eliminate posatium.
