Answer 2

Your heart and kidneys are two important organs in your body. They work together to keep you healthy. When one is affected, the other is too. In other words, your heart can affect the health of your kidneys, and your kidneys can affect the health of your heart.
What does the heart do?
The heart is a muscle that pumps blood filled with oxygen to all parts of your body. This job keeps every cell, organ, and system alive within your body. To move blood to each part of your body, your heart relies on your blood vessels. Together, the heart, blood and blood vessels make up a system called “the cardiovascular system.” Think of it as a delivery system. The delivery system moves blood from the heart carrying oxygen and nutrients throughout your body and also picks up waste products so that your body can get rid of them.
What do the kidneys do?
Your kidneys are two bean-shaped organs and are usually about the size of your fist. They are located a little below your rib cage and to the left and right of your spine. Your kidneys are powerful chemical factories and have the following jobs:
Clean your blood of waste products and extra water
Help control blood pressure
Keep bones healthy and strong
Help make red blood cells
Keep the balance of minerals in your blood (like sodium, phosphorous, and potassium)
How do the kidneys and heart work together?
The heart pumps blood filled with oxygen through all parts of your body, including the kidneys. The kidneys clean the blood, removing waste products and extra water. Without the kidneys, your blood would have too much waste and water. Without the heart, your kidneys would not have the oxygen filled blood needed to do its many important jobs. Without the help of your kidneys, the heart would be working too hard or would not function at all. A healthy functioning cardiovascular system is important for your kidneys to their job.
