1. Renin: Renin is an enzyme produced and released by the kidneys in response to low blood pressure or low blood volume. Its primary function is to regulate blood pressure by initiating a series of reactions that ultimately lead to the production of angiotensin, a hormone that constricts blood vessels and increases blood pressure. Renin also plays a role in the regulation of electrolyte balance and fluid volume in the body.
2. Angiotensin: Angiotensin is a hormone that is produced in response to the action of renin. It acts to constrict blood vessels, increase blood pressure, and stimulate the release of aldosterone from the adrenal glands. Aldosterone, in turn, helps to regulate blood pressure by increasing the reabsorption of sodium and water in the kidneys. Angiotensin also plays a role in the regulation of electrolyte balance and fluid volume in the body.
3. Atrial Natriuretic Factor (ANF): Atrial natriuretic factor is a hormone produced by the heart in response to high blood pressure or high blood volume. Its primary function is to promote the excretion of sodium and water by the kidneys, which helps to lower blood pressure and reduce blood volume. ANF also acts to dilate blood vessels and inhibit the release of renin and aldosterone, further contributing to its blood pressure-lowering effects.
4. Erythropoietin: Erythropoietin is a hormone produced primarily by the kidneys in response to low oxygen levels in the blood. Its main function is to stimulate the production of red blood cells in the bone marrow, a process known as erythropoiesis. By increasing the number of red blood cells, erythropoietin helps to improve oxygen delivery to tissues and organs, thereby maintaining proper oxygen levels in the body. Erythropoietin is also important for regulating iron metabolism and maintaining overall red blood cell production.

Renin
- Source: Juxtaglomerular cells in the kidneys
- Function: Regulates blood pressure by controlling the production of angiotensin II
Angiotensin
- Source: Produced from angiotensinogen by renin
- Function:
- Vasoconstriction (narrowing of blood vessels)
- Stimulation of aldosterone release (which increases sodium reabsorption in the kidneys)
- Stimulation of thirst
Atrial Natriuretic Factor (ANF)
- Source: Atrial cells in the heart
- Function: Counteracts the effects of renin-angiotensin system by:
- Vasodilation (widening of blood vessels)
- Natriuresis (increased sodium excretion in the kidneys)
- Diuresis (increased urine production)
Erythropoietin (EPO)
- Source: Kidneys (primarily) and liver
- Function: Regulates red blood cell production by:
- Stimulating the bone marrow to produce more red blood cells
- Increasing the production of hemoglobin, the oxygen-carrying protein in red blood cells
- Erythropoietin production is stimulated by decreased oxygen levels in the blood
- Source: Juxtaglomerular cells in the kidneys
- Function: Regulates blood pressure by controlling the production of angiotensin II
