Answer:
Erythropoietin
Step-by-step explanation:
Erythropoietin is a hormone synthesized by the kidney, more specifically by cells adjacent to the renal proximal tubules, which regulates erythropoiesis (red blood cell production, also known as red blood cells) in man and other animals. That is, it regulates the blood volume in the body, helping the volume to be in the proper amount.
This hormone is widely used in the treatment of various types of anemia, preparations of surgical procedures in which there is great blood loss, replacement of blood levels after surgery, therapy of chronic conditions (such as hepatitis), cancer treatments, chronic kidney failure, blood disease, neoplasms, autologous transfusion programs and orthopedic surgeries.
