The Wonder Organs: How Kidneys Work
March is the official “Kidney Month”! So, let's learn how kidneys, one of the most important organs in the body, work. You may know that Kidneys are the official “filter” for the human body but they are also responsible for so much more!

It does this by producing the the hormone aldosterone.1 Additionally, kidneys maintain levels of sodium, which if left unbalanced, could increase blood pressure. Increased blood pressure can cause heart disease, further kidney damage, strokes, and more.2
Red Blood Cell Production
A healthy kidney manufactures the hormone EPO, which signals the bone marrow to create new red blood cells. Red blood cells are responsible for carrying oxygen throughout the body. Without enough red blood cells, people expierence Anemia. This condition can cause fatigue, weakness, irregular heartbeats, shortness of breath, and more.3
As mentioned, the kidneys are the primary filters for the body. They remove toxins, like acids and minerals4, that would otherwise harm the body.
Minerals: The body needs levels of sodium, potassium, and calcium too be balenced. Too little and the body can’t function properly. Too much and the body will get damaged.
Acids: Filtering acids helps maintain the blood's pH balance.

According to You and Your Hormones, the kidneys “stimulate the uptake of calcium from food, which is extremely important for bone health.6 ”
