Explanation:

1. Analyze the first option: Hormones are released in very low concentrations, not high amounts, so this is incorrect.
2. Analyze the second option: Hormones are specific to target cells with matching receptors, not all cell types, so this is incorrect.
3. Analyze the third option: Hormones are secreted into interstitial fluid and then enter the bloodstream for transport to target cells, which is correct.
