How your kidney work

2012-09-11 11:56

The kidneys are two bean-shaped, fit-size organs located on either side of the rib cage. Each kidney is about 5 inches long, 3 inches wide. Put your hands on your lips, and then slid your hands up until the ribs can be touched. Right, here they are.

When the heart pumps blood, no less than 20% of the blood goes directly to the kidneys through renal artery. The blood enters kidneys and is filtered by glomeruli. Purified blood is sent out via renal vein and goes back into the systemic blood circulation.

Your kidneys filter about 200 liters of blood every single day. How much is that? Enough to fill a large bathtub. Amazing, isn’t it? 2 liters of toxins, wastes and extra body will be excreted from the blood. Those unpleasant things would flow out through urine into bladder afterwards. When we urinate, those things are released accordingly.

Be more exact, the function of kidneys depends on millions of nephrons, which become the core of a kidney. In the nephron, glomeruli, which are many tiny blood vessels, filter metabolic wastes, excess fluids and toxins.

Why are kidneys so important to us?

Give you a chance to name at least 3 most vital organs in your body. You probably list heart, brain, lungs before even think of kidneys. Yes, your kidneys work day and night, but few people realize how important they are. Now, let’s imagine if cut your kidneys off, what would happen? Uremia is what usually forms as a result of malfunctioned kidneys. Without at least one healthy kidney, it is hard enough for one to survive; even you are equipped with a smart brain or extremely healthy heart. Why? This is because the kidneys are responsible for several essential roles:

1. Remove wastes, toxins and excess fluids from the body, which exactly the most essential function among all;

2. Keep electrolytes and acid-base in balance;

3. Release steroids, take part in the production of RBCs, and produce active form of vitamin D etc;

4. Produce urine

A great deal of toxins and wastes couldn’t be eliminated from blood once kidneys fail. What are the consequences? Those toxins would circulate through the blood flow to the whole body. Try to imagine that your healthy heart bathe in toxins all day long, how long could it survive? Now, get it? Hope when finish this article, you not only realize the importance of your kidneys, but also begin to protect them in your daily lives. Good luck with that!
