for blood to flow through a vessel or across a heart valve, there must be a force propelling the blood. This force is the difference in blood pressure (i.e., pressure gradient) across the vessel length or across the valve.
Angiotensin receptors and regulation of fluid balance in the body along with sodium retention.
Sodium is a mineral that helps to regulate water balance in the body, controlling blood pressure and encouraging the nerves to work accordingly. In the human body, you would find sodium in the blood.
Sodium (Na)
Sodium is a very important mineral to the body. Sodium is mineral that is required for keeping blood pressure at a normal range. It is also useful for maintaining a fluid balance in the body and helping the nervous system communicate.
No sodium does not tell genetics. Consuming excessive sodium over period of time can cause condition such as increased blood pressure and this condition is sometimes found to be genetic disease (passed onto offspring from parents). However sodium levels in our blood are tightly regulated and it is also very important for sodium- potassium pumps in our cells.
The renin-angiotensin-aldosterone system is known to play an essential role in controlling sodium balance and body fluid volumes, and thus blood pressure.
Aldosterone is both responsible for absorption of sodium and excretion of potassium. If it is regulated by the level of potassium in blood, then we have negative feedback as high levels of aldosterone causes a decrease in potassium level in blood. If it is regulated by the level of sodium in blood, the story is just the opposite and we have positive feedback. -my own conclusion from several researches-
Sodium maintains the balance of fluid in a person's body.
The formula unit of sodium chloride is NaCl.

sodium along with potassium maintains the electrolyte balance in our body
When it is necessary to hydrate the organism and to balance the sodium concentration in blood.
