An Overview of Human Body for Kids

The organs, muscles, nerves, and bones work hard under your body's skin. Because of them, you are alive and healthy without even realising it. But don't you have a question about how these body systems work? You might know about the head, shoulders, knees, and toes, but are there other important body parts present? So let's study them also in this article.  

The body system is an organisation of varying numbers and types of organs so arranged that together they can perform different functions for the body and keep us alive. Examples are the digestive system, excretory system, etc. 

Keep reading this article to learn about the body system for the kid, the human body for kids, and parts of the body for kids.

Parts of the Body for Kids

Let's discuss about all the body parts one by one.

1. Parts of the Arms

Every part of the arm has a particular function to perform. Some of its parts help with bending, and others help with experiencing the sense of touch. And the most important part that differentiates humans from most other animals: is the opposable thumb!

2. Parts of the Legs

The list of body parts divides the legs into different sections according to their location and function—The knee comes under the parts of the leg.

3. Parts of the Torso

Have you heard about “strengthening your core,” but what does it mean? The core is the middle portion of the body, where the arms and legs branch off. These are the external parts of the core of the body.

External Human Body Parts for Kids

The external human body parts for kids contain skin, hair, and nails. The external parts of the head include the eye, ear, nose, mouth, tongue, and teeth. The limbs include the arm and leg, and how to forget the hand, foot, and knee. The bones and muscles are holding up the body and making moving possible. 

Human Body Systems

The human body parts for kids contain the following systems of the body. Healthy body functions are not possible without these systems.

1. Nervous system

The two main parts of the nervous system are the central and peripheral nervous systems. Due to the nervous system, all the organs present in the human body can communicate with each other.

2. Circulatory System

The circulatory system is responsible for carrying nutrients all around the body. One of the most important functions of this system is to bring oxygen from the lungs to the other body cells. Also, the system helps to provide nutrients and hormones to muscles, tissues, and other organs throughout the body. 

3. Digestive System

The digestion of food is important to distribute nutrients and other vital elements. When the food is chewed, it undergoes a process called digestion. The process of digestion begins at the mouth and ends at the anus. This system plays a vital role in the breakdown of food into protein, carbohydrates, and nutrients.

4. The Urinary System

Not all waste materials are excreted through the digestive system, so the urinary system balances the body by eliminating the waste through urine. This system is also known as the renal system. Due to this system, the liquid waste is thrown out of the body.

5. The Respiratory System

A body can't function without oxygen. The respiratory system takes oxygen through respiration. The respiration process is known as breathing. During breathing, your body takes oxygen in and expels carbon dioxide from the body. We can breathe with the help of this system. This system purifies the air that we breathe. 

6. Skeletal System

The skeletal system provides support to the vital organs. This system gives structure to the body. The skeletal system includes 206 bones, including connective tissue such as tendons, ligaments, and cartilage. This system provides the structure and shape of the body.

7. Muscular System

The muscular system helps the body move. When the brain sends any kind of signal to a muscle in the body, the neurotransmitters tell the muscle what to do. This important function this system plays is to allow us for any kind of movement.

Different Body Parts

Different Body Parts


The human body is made up of different parts. The study of these body parts is known as anatomy. Every part of the body has a particular function to do. The study of body functions is known as physiology. The healthy working of the body is possible due to the system inside it. These systems include the digestive system, nervous system, skeletal system, etc. The external parts of our head are the eyes, ears, nose, cheeks, and lips. A proper diet can keep our body and body parts healthy and safe. The system of the body that prevents humans from being attacked by bacteria is known as the immune system. In this article, we have covered external human body parts for kids.
