Have you ever wondered how you can see the colors, listen to your favourite song, taste chocolates or feel warm and cold? This is all possible because of the sense organs of our body. These special organs help our body to understand the changes happening around us. Without our sense organs, we cannot smell, feel, hear, taste, or see anything. This means our sense organs let us enjoy our favourite snacks, watch our favourite movie or hear someone call our name. Therefore, these organs are a highly important part of our body and we must know their names, functions and importance so that we take care of them.

What are Sense Organs

Our body is made up of various organs that help us stay active and perform various functions. For instance, some organs inside our body, like the liver, help our body to digest food. Other organs that help us sense the world around us are called our sense organs. These sense organs help us sense smell or heat, etc. Our nose, eyes, tongue, skin and ears are the five sense organs of our body that help us sense the world around us.

Why are Sense Organs Important

Our sense organs are vital for our survival and safety. Imagine crossing the road without being able to see. Eyes and ears are the sense organs that help us see and carefully hear the vehicles while crossing the road. We rely on sense organs to detect any danger and stay safe. These organs signal our brain about any potential danger. Like seeing flames send a signal to our brain about fire breaking out or when we feel heat from an object, we quickly pull our hand away from that object. They help us brain to quickly respond to threats. Our daily activities like reading, listening and eating are also possible due to our senses. Therefore, these senses are crucial for us.

Five Main Senses Organs

Our body has five sense organs that help us feel the changes happening around us.

Sense of Sight: Our eyes allow us to see the things around us. With the help of our eyes, we can see, understand and compare various things in our surroundings, such as checking how far or near an object is from us. It helps us judge distances, speed, height, etc. Our eyes are a round, ball-shaped organ placed in a socket in front of our skull. It captures the image through sensory cells called the retina and sends it to the brain to decide the response. In the middle of our eye is a dark circle called the pupil. The ring around the pupil is called the iris.

Sense of Hearing: Our ears help us hear sounds like the horn of a car, birds singing, our friends calling our name, etc. The outer ear catches the sound, which travels through the narrow canal to reach the eardrum, where it vibrates. There is a tiny bone inside our ear that carries these vibrations deeper inside our ears. It also helps us maintain the balance of our body. This bone is attached to an auditory nerve, which sends signals to the brain.

Sense of Smelling: Our nose helps us experience all different kinds of smells. It assists us in knowing if the food is fresh or stale. These are specialised nerve cells in our nose called olfactory receptors that help detect different kinds of odors by sending signals to the brain. Our nose also helps us breathe. There are two openings in our nose called nostrils that have tiny hairs inside them to filter the dust particles entering our body. The air entering through our nose goes into our body and comes out through our mouth.

Sense of Taste: The tongue helps us to taste our food. There are tiny taste buds on our tongue that detect the taste of food as sweet, sour, bitter, spicy, etc. The tip of our tongue can detect the sweetness in food. The sides of our tongue tell if the food is salty or sour, while the back of our tongue detects the bitter taste. Our tongue also helps us in speaking and swallowing our food. We must brush our teeth and keep our tongue clean to avoid bad breath.

Sense of Touch: Skin is the largest organ covering our whole body that helps us feel things like hot, cold, rough, smooth, etc. All kinds of substances, such as solid and liquid, we can touch and feel through our skin. The tiny little nerves present on our skin help us feel everything. Our skin protects us from germs.

Our skin is the largest organ of our body.
There is a small bone inside our ears that also helps to maintain our balance.
There are an average of 2,000 to 8,000 taste buds on our tongue.
Our sense of smell is closely linked to taste, that is why when our nose is blocked, we often feel the food is bland.
