The kidneys play an essential role in our bodies' functioning. They perform waste excretion, water level balancing, blood pressure regulation, acid regulation, and red blood cell regulation. When the kidneys sense that your blood is in a hypoxic state, they send feedback through a negative loop or a distress signal by releasing an erythropoietin hormone.
Hypoxemia can be caused by heart conditions, asthma, emphysema, and sleep apnea. This hormone stimulates the bone marrow to produce more oxygen-carrying red blood cells. These cells come to the kidneys from the abdominal aorta, the oxygen is used, and then the blood leaves the kidneys toward the inferior vena cava and then on to the heart for reoxygenation. A person's kidneys receive about 1.2 liters of blood each minute, and they are an integral part of your body's performance.
