Verified step by step guidance

Identify the primary function of each substance listed: Erythropoietin, Renin, Aldosterone, and Cortisol.

Understand that the kidneys play a crucial role in regulating blood pressure through the renin-angiotensin-aldosterone system (RAAS).

Recognize that Renin is an enzyme produced by the kidneys that initiates the RAAS pathway, leading to increased blood pressure.

Differentiate between the roles of the substances: Erythropoietin stimulates red blood cell production, Aldosterone regulates sodium and water balance, and Cortisol is a stress hormone.

Conclude that Renin is the substance produced by the kidneys specifically to help regulate blood pressure.
