Key Differences Between External and Internal Organs
Human body offers an endless portion of study. Human body is made up of external organs and internal organs that help in running the system throughout life. External and internal organs are defined in different ways.
External Organs of Human Body
An organ is a structural unit made up of tissues that perform a certain function. The external organs of the human body are visible and differ from person to person. There are 78 organs in all. Each bone and tooth is tallied just once. Counting each bone and tooth separately brings the total number of organs to 315. Counting every ligament and tendon would bring the overall number of organs much higher. Not all organs are required for survival. For survival, the brain, heart, liver, and at least one kidney and lung are required. It is possible to die if any of these five important organs loses all of its function. There are different internal and external organs which are vital for the study of human body function.
Internal and External Organs
The five sense organs in our body play a critical part in our lives. They are linked to our minds. Aside from these organs, our bodies have a variety of additional organs. They collaborate in several groupings. A system is made up of a number of organs that work together to provide important tasks for our bodies.
Let Us Check How:
Sense of Sight- Our eyes assist us in seeing the world around us. Looking at an object teaches us about its shape, size, and colour.
Sense of Hearing- Our ears assist us in hearing various noises. We learn the sounds of many objects.
Sense of Smell- Our nose aids us in smelling. Smells come in a variety of forms. These odors are detected by our nose and sent to our brain.
Sense of Taste- Our tongue detects sweet, sour, salty, and bitter flavours. Taste buds on the tongue provide information about various flavours.
Sense of Touch- We can tell if something is cold, hot, rough, smooth, hard, or soft by filling it with our skin. The most delicate portions of our bodies are our fingertips. Lips are also quite sensitive.
What are External Organs?
External organs of the human body consist of different parts. These external organs are vital to help run our internal organs and keep the body functioning. The eyes, ears, nose, tongue, and skin are the body's external organs list. These organs are visible. Our sensory organs are these exterior organs. Sense organs are vital elements of our bodies because they provide us with information about our environment. You can have a better understanding with external organs charts.
Place yourself in front of a mirror. Examine various bodily components. Our bodies are made up of several components.
Below are the External Parts of the Body and Their Functions
Head- Turn your head to the side. Let's lift and lower our heads. Because of the neck, we are able to do various motions. Let's have a look at the other parts of our skull and how they work.
Neck- The neck is supported by the shoulders. The chest, stomach, waist, back, and hips are all located below the shoulders. Picking up a dropped pencil, for example, requires bending at the waist. We can bend forward, sideways, and somewhat backward.
Arms and Legs- Let's use our arms and legs to grip a pencil in our hands. Swing our arms back and forth. Our arm should be bent at the elbow. Bend your knees. Jump about a little. Now take note of which exterior body parts move freely, as well as the functions that these external body parts may perform.
What are Internal Organs?
Just like the external organs of the human body, there are internal organs too. One major difference between internal and external organs, one cannot view internal organs and have vital responsibility for the functioning of the body.

Some of the Essential Internal Body Parts Are:
The Brain
The brain, which is housed within the skull, is the nerve system's command centre. Muscle control and coordination, sensory reception and integration, speech production, memory storage, and cognition and emotion elaboration are all processes of the brain.
Lungs
The lungs are two cone-shaped sponge-like organs that occupy the majority of the chest cavity. Their primary job is to transport oxygen from the lungs to the bloodstream while also exhaling carbon dioxide.
Liver
Lies on the right side of the body's abdominal cavity, the function of the liver to supply blood, and composition is the same throughout the body. There is a process happening in the liver involving extracting fats, filtering harmful substances and producing urea.
Kidneys
These two-bean shaped internal organs are located just right back of the abdominal cavity. There are two kidneys in the human body. One unique thing about this internal organ is that humans can survive with one kidney if any of the either is damaged.
Heart
A hollow and muscular organ keeps pumping blood through blood vessels.Like these, there are other internal organs which support external organs to keep the body of the human being active and healthy.
Conclusion
External organs of the human body carry different shapes and sizes person to person. Any damage to these internal and external organs can create health issues.
FAQs on External and Internal Organs Explained
1. What are external and internal organs?
External organs are the parts of the body that are on the outside and visible to us, like our eyes and nose. Internal organs are located inside our body and are protected by skin and bones, so we cannot see them. Examples of internal organs include the heart and lungs.
2. Can you give some examples of external organs and their functions?
Our main external organs help us sense the world around us. These are often called our sensory organs. Common examples include:
- Eyes: To see the world.
- Ears: To hear sounds.
- Nose: To smell different things.
- Tongue: To taste food.
- Skin: To feel touch, temperature, and pain.
3. What are some of the most important internal organs in the human body?
The human body has many internal organs, but some are considered vital for survival. These include the brain, which controls our thoughts and actions; the heart, which pumps blood; the lungs, which help us breathe; the liver, which cleans our blood; and the kidneys, which filter waste.
4. What is the main difference between an external and an internal organ?
The primary difference is their location and visibility. External organs are on the body's surface and we can see them, while internal organs are enclosed within the body. Functionally, external organs often interact directly with our environment (like eyes seeing light), whereas internal organs perform tasks essential for the body's internal systems to work properly.
5. Why is the skin considered an important external organ?
The skin is the body's largest organ. It's incredibly important because it acts as a protective barrier, shielding our internal organs from germs, injury, and sunlight. It also helps regulate our body temperature through sweating and gives us our sense of touch.
6. How do internal and external organs work together?
Internal and external organs constantly work as a team. For instance, when you see a ball coming towards you, your eyes (external organ) send a signal to your brain (internal organ). The brain processes this information and then tells your leg muscles to move so you can kick the ball. This coordination is essential for almost every action we perform.
7. Are all internal organs necessary to live?
No, not all of them. We have vital organs like the heart, brain, and liver that are absolutely essential for survival. However, a person can live a healthy life without certain organs, such as the appendix or the gallbladder. It's also possible to live with just one kidney or one lung.
8. What is the best way to learn the locations of different internal organs?
Using a human body diagram or a labeled chart is one of the easiest ways to learn. These visual aids clearly show where each organ, like the stomach, liver, and intestines, is located inside the body. This helps in understanding how they are positioned relative to one another.
