The correct answer is Erythropoietin.

Key Points

  • Erythropoietin (EPO) is a hormone that helps your body maintain a healthy red blood cell count and is used to treat anemia. 
  • EPO is produced in the kidneys and stimulates the bone marrow to produce red blood cells.
  • It's also known as hemopoietin.
  • EPO is also thought to have anti-inflammatory, antioxidant, and antiapoptotic properties.

Additional Information

  •  Cholecystokinin plays a fundamental role in the digestive process. 
  • When fats and proteins enter our small intestine, cholecystokinin triggers your gallbladder and pancreas to contract.
  • Serotonin plays several roles in our body, including influencing learning, memory, and happiness and regulating body temperature, sleep, sexual behavior, and hunger.
  • Somatostatin's main function is to inhibit the production of hormones and secretions in the endocrine and exocrine systems.
