All About Body
Our bodies are designed for hearing, speaking, movement and reproduction. We can see, think, reason, create, feel pain and pleasure. We really are a wonder of nature and I doubt if we ever really stop and take the time to think about the complexity of it all.
Each part of our body has its own specific purpose – eyes see, ears hear – and when it is all working at its optimal level, life is good. People come in different packages but on the inside we are all the same. Let’s take a look at what is going on in our bodies.
The heart is…well, the heart of our body. Without the beating functions of this organ we could not survive. The human heart is only about the size of your fist and has a meat-like appearance. It is found nestled and protected in the middle of the chest between the lungs. It is also divided up into four chambers; left atrium, right atrium, left ventricle and right ventricle.
Since the heart is considered a muscle it works hard during our lifetime. It pumps blood throughout our system and generally beats about 100,000 times a day – that’s about 2.5 billion heartbeats over a lifetime. With each beat of the heart, blood is being pushed through all the vessels in the body, which is about 60,000 miles (96,560 kilometers) of them.
Our lungs are just as important as the heart. Without these we would not have the ability to breathe. As we take in oxygen it passes through the lungs and is released out in carbon dioxide. They process on average of 11 litres of air each day.
The lungs are also different in size. The left one is smaller, making room for the heart, while the right one is slightly bigger. Both lungs are also divided into lobes. The right lung has three lobes, while the left features only two. Despite their size, healthy lungs are pink in appearance and sponge-like in texture. Inside there are around 30,000 bronchioles with hair-thin vessels that connect to tiny air sacs called alveoli – 600 million in fact.
Our kidneys are also important organs. These are responsible for cleaning the toxins out of our blood stream, for stimulating the production of red blood cells, as well as getting rid of the toxins and excess fluids through our urine. This is a huge and important job to do, despite the fact that each one is only about the size of a computer mouse.
Healthy kidneys filter about 189 liters (50 gallons) of blood each day, working its way through 140 miles (225 kilometers) of tubes, vessels and millions of tiny filters found inside of the kidneys. The great thing about these organs are you always have a spare. If one of your kidneys is damaged you can still live a normal life with just one.
Our bodies are a complex design that works together in harmony to keep us healthy and happy.
