The kidneys are located in the retroperitoneal space, which is the area behind the abdominal cavity. They are bean-shaped organs that filter waste products from the blood and produce urine. The kidneys also help to regulate blood pressure and produce hormones that are important for red blood cell production and bone health.
The liver is located in the upper right abdomen, below the diaphragm. It is a large, lobed organ that performs many important functions, including:
- Metabolizing carbohydrates, fats, and proteins
- Producing bile, which helps to digest fats
- Storing vitamins and minerals
- Detoxifying the blood
- Regulating blood sugar levels
The heart is located in the chest, between the lungs. It is a muscular organ that pumps blood throughout the body.
