There is no organ like the heart when it comes to love. Perhaps it earned its reputation for love because it does such a great job at keeping you alive. Every single minute, it moves 5 litres of blood (1.3 gal.) though 100,000 km. (62,000 mi.) of arteries, veins, and capillaries. It never takes a vacation. Every single day of your life, it takes care of you. True love never was more loyal. You can learn what is going on in your heart when you hear the “lub dub” sound, where the blood heads after it is pumped out of your heart, and how it flows through the organ itself.

Introduction To The Respiratory System

Did you know that your left lung is smaller than your right lung? That’s because most of your heart sits on the left side of your body and the lung must be smaller to make room for the heart. The lungs are responsible for taking in oxygen and expelling carbon dioxide from your body. All of the magic happens in the alveoli, tiny sacs of air. There are millions of these sacs which makes for a very intricate system for respiration. To learn how lungs help you live, watch these introductory videos.

Introduction To Urinary System

Urine the right place, if you want to learn more about the renal system. (All kidding aside, the kidneys do much more than simply make urine.) Your kidneys filter all the blood within your body every 30 minutes. Imagine dirty pool water packed with algae. You will get a crisp, clean blue pool after you put an algae filter in it that removes all the dirty bits. The kidneys work just like a pool filter but they remove wastes which are toxic to the body if they are allowed to build up. They maintain water and electrolyte balances in your body with just two paired organs to do the job.
