5 Vital Organs In The Body And The Roles They Play In Our Survival


Viral News Boy :- The human body is a beautiful, complex and highly organized structure. It is everything that makes up, well, you. Even when you are asleep, it keeps working to make sure you are hale and hearty.

Our body is made up of billions of cells that work together to make sure that our tissues work connectively, which in turn makes sure that our organs also work hand in hand for a proper functioning of our systems.

Generally, there are 78 organs in the human body that work hand in hand to make sure the body is functioning well. However, some of these organs are more vital than others to our survival. A problem with any of these vital organs can quickly become life threatening.

In this article, we’ll be taking a look at what these vital organs are, and the roles they play in our survival.

1) The Brain 

The brain is our body’s control centre. It forms the core of our central nervous system alongside the spinal cord. It controls and coordinates our actions and reactions, thoughts, memory and speech, movement of our arms and legs, motor skills, vision, breathing, temperature, hunger, and the function of many organs within our body.

The human brain is large enough, that the amount we can learn is not limited by the brain’s storage capacity. As time goes by, however, old information is sometimes pushed out of the brain for new memories to form.

Certain behaviors like smoking, high sugar consumption, air pollution, sleep deprivation, working your brain during illness and so on, can prevent the brain from reaching its full potential. 

2) The Heart 

Our heart is the most important organ in the circulatory system, and is responsible for pumping blood to all parts of our body. The blood pumped by our heart provides our brain and body with continuous supply of oxygen and nutrients it needs to function, while also carrying away unwanted carbon dioxide and waste products.

The heart also has electrical impulses that help to ensure that it beats at a proper rate and consistent rhythm. The heart rate increases when our body needs more blood, such as during intense exercise, and decreases during times of rest.

Because our heart is crucial to our survival, it is important to keep it healthy with a balanced diet and exercise, and avoid things that can damage it, like smoking, excessive intake of salt, drinking soda, drinking alcohol excessively, sitting for hours, ignoring our sleep quality and so on.

3) The Lungs 

The lungs are a pair of spongy, air-filled organs located on either side of our chest. Their main function is to extract oxygen from the air we breathe, and transfer it into the bloodstream, while also removing carbon dioxide which we exhale.

In most cases, one healthy lung should be able to deliver enough oxygen and remove enough carbon dioxide for our body to stay healthy.

Everytime we engage in smoking, the lungs are the primary organs that are affected. So try as much as possible to avoid smoking. You should also minimize exposure to outdoor air pollution as well as indoor pollutants that can damage your lungs.

4) The Liver 


The liver is the most important organ in the metabolic system. Its functions include the removal of waste products and foreign substances from the bloodstream, breakdown of drugs, secretion of bile, regulation of blood sugar levels and the creation of essential nutrients.

The liver is the only solid internal organ that is capable of full regeneration. This means that, everytime the liver is damaged, it can develop new cells and regrow to its original volume. However, regular unhealthy behaviors like drinking too much alcohol, can reduce its ability to regenerate.

Some of the best things you can do for your liver is to keep a healthy weight, drink plenty of water, eat a healthy diet and get regular exercise.

5) The Kidneys 

The kidneys are a pair of bean-shaped organs located in the back of our abdomen. Their main job is to cleanse the blood of toxins and transform the waste into urine.

A person can live with just one kidney. When a person is experiencing severe kidney failure, dialysis can filter the blood until they get a kidney transplant or their kidney recovers some function.

To keep your kidneys in good health, avoid overusing painkillers, eating processed foods, not drinking enough water, missing out on sleep, eating too much meat, eating too many foods high in sugar, smoking and drinking alcohol in excess.

Now that you know the roles these organs play in our survival, will you make good effort to live a healthy life?
