An Overview of the Human Organs

Kids, do you know how many organs we all have? Our human bodies contain lots of different organs all working together. Firstly, an organ is a part of the body that performs a specific job. Each organ has its particular job to do. Inside our head, protected by our skull, is our brain. On our chest are our heart and lungs, both so close to one another. The nose, ears, eyes, and skin are a few other organs we have outside our body. Some of the body's vital organs are the lungs, kidneys, heart, intestine, and brain. Let’s learn about these organs in detail.

Major Organs of the Body

All organs of the body are crucial in their way. But some vital organs are discussed here. We have the lungs, the heart, the kidneys, the intestine, the stomach, the brain, and many more. These organs work together for the proper functioning of a body. So, let's learn about some of the major organs of the body.

  • Heart

The heart is a vital part of the body. It is known as the symbol of love and is a nature's wonder. The heart is located on the middle-left side of our chest. The heart pumps blood through the circulatory system and provides oxygen-rich blood to the other body parts.

  • Brain

It is due to an essential organ in our body called the brain. Our brain is the 'boss' of our body as it controls everything we do. The brain controls things like feeling, learning, talking, dancing, and even breathing. 

  • Kidneys

There is a pair of kidneys inside the human body. Kidneys are located in the upper abdominal area against the back muscles on both the left and right sides of the body that act like filter devices. Kidneys clean the blood and separate waste compounds from the blood when it passes through the kidneys. 

  • Lungs

Breathing air is necessary for keeping us alive, and the lungs are the vital organ for helping us with breathing. They are one of the largest organs of our body. They work with our respiratory system to allow us to take in fresh air and get rid of stale air.

The System of Organs

In the above paragraph, we read about the vital organs of our body. But children, our organs work in a complex system associating with other organs. So now, let's learn about the system of organs.

  • Circulatory System

The heart works in the circulatory system and pumps oxygen-rich blood to the body's organs. The circulatory system contains blood vessels in which the blood travels. 

  • Nervous System

Our nervous system is the in-charge of every work our body does. A nervous system is a network of organs and nerves that send signals throughout the body. Nerves are associated with the brain, and they are the main components for providing signals to work.

  • Respiratory System

We breathe oxygen through our nose and store a portion of it in our lungs. Lungs play a significant role in filtering the air we inhale and are a vital organ of the respiratory system. Lungs have small balloon-like structures called alveoli which fill them with oxygen and let go of carbon dioxide, the bad air.

  • Excretory System

The excretory system is made up of the urinary organs, which produce and expel urine from the body. The major role of the excretory system is to get the body rid of waste substances. A Urinary bladder, the ureters, the urethra, and the kidneys constitute the excretory system that helps to clean our blood. 

  • Digestive System

The digestive system is a tube of organs beginning with the mouth, and extending as far as the anus. The digestive system is made up of many different parts all connected.

  • Reproductive System

The reproductive system is a general term that describes the organs and their functions in human beings and the lower animals, which are involved in reproduction. The function of the reproductive system can be summarized as producing, maintaining, and eventually transporting spermatozoa (in males) for fertilization of ova (in females) as part of sexual reproduction. 

  • Musculoskeletal System

A musculoskeletal system is the body's support and connective tissue. It consists of bone, cartilage, ligaments, tendons, and many other connective tissues that help to support and protect the various body organs. The function of a musculoskeletal system is passive (not requiring conscious thought).

Fun Facts About Organs

Let's learn some fun facts about organs.

  • A human heart pumps around two thousand gallons of blood every day. Heart beats about one hundred thousand times in one day and approximately thirty-five million times a year. The human heart will beat more than three billion times during an average lifetime.

  • A human brain generates about 12-25 watts of electricity. This electricity is enough to power a low-wattage LED light. 

  • If you habitually hold your pee for a long time, you're subjecting yourself to severe long-term effects, including a higher risk of infection. Holding pee weakens the bladder muscles.

  • The left lung is slightly smaller than the right lung in humans. This is because the right lung consists of three lobes whereas the left lung has two lobes. And also, the left lung gives space for our heart to fit in.


Summary

In this article, we learned some interesting facts about the human body. We learned that the human body is an amazing creation of nature. Some human organs are internal body parts such as the heart, kidneys, lungs, stomach, brain, and liver while others are outside the body, such as the nose, eyes, ears, and skin. Organs within the organ system perform a specific task. If any of our body's organs face proper functioning issues, the whole human body suffers. All the organs are interconnected with one another for the proper functioning and maintenance of the body. An individual needs to take appropriate care of the body to safeguard these organs. We hope you enjoyed reading this article, in case of any other doubts, feel free to ask in the comments.
