Our Sense Organs and Body System

"Our Sense Organs and Body System"

Hell, guys, I have already written about Human’s body, this time I am elaborating our sense organs and our body systems.

We have five sense organs. These sense organs are tongue, nose, ears, skin and eyes. Here are some paragraphs about them.

                               We taste with our tongue. There are thousands of little taste buds on our tongue. These taste buds send message to our brain. Our brain tells us if the food is sour, sweet, bitter or salty. The buds for each taste are on different parts of the tongue.

Health Tips:

  • Clean your tongue when you brush your teeth.
  • Don’t eat or drink very hot food.
  • Rinse your mouth with clean water, after eating.



                         Our ears help us hear. Each ear is made of three parts, the outer ear, the middle ear and the inner air. The outer ear is the part that is seen. This part acts like a cup and cathes sound waves. The middle ear contains eardrum and the three smallest bones. The inner ear is called the cochlea. A nerve carries a message of sound from the cochlea to the brain. The sound travels from outer ear to the eardrum. From eardrum it travels to the three bones and then to the cochlea. Cochlea sends the message of sound to the brain.

Health Tips:

  • Don’t put anything into your ear.
  • Don’t swim in dirty water.
  • If you have pain in your ear visit to the doctor.



                        We use our skin to touch and feel things. Nerve endings are present in the whole skin. These nerve endings send messages to the brain. The skin helps us to feel heat or cold, smooth or rough, soft or hard and pressure. It also helps us to feel pain. The fingertips are the most sensitive parts of our body.

Health Tips:

  • Wash your hands with soap before and after eating and after using the toilet.
  • Eat healthy food and drink plenty of water.



                            We smell with our nose. Inside of the nose is lined with mucous membranes. These membranes have nerve endings. Smells are made of fumes of different substances. As the air goes through our nose to lungs, nerve endings in our nose detect the smell. The nerve endings send the message of smell to the brain. The brain tells whether the smell is pleasant or unpleasant.


Health Tips:

  • Don’t put anything into your nose.
  • If you have a nose bleed, sit in a chair. Bend your head a little in front. Call the doctor.



                        Our eyes help us to see things. We can see cornea, pupil and iris of the eye. The pupil is the hole in iris. Light passes through the pupil Iris is the colured part of our eye. Behind the iris, lens is present. The lens makes image on the retina. A nerve carries message of the image from retina to the brain.

Health Tips:

  • Use proper light when studying or using the computer.
  • Eat healthy foods such as vegetables, fruits, milk and eggs.

Our Body System:

                                 Our body is a complex machine. Many parts and systems work together to carry out our body functions. Some of the important systems of our body are elaborated below, but first take a look of a video shared below:

1-      Skeletal System:

                                            Bones form the skeletal system in our body. There are over 206 bones in our body. The framework of bones is called skeleton. The skeletal system supports the body and gives it shape. It also protects the soft organs inside our body.

"The tips of our nose and ears are made up of something called cartilage, which is softer than bone."

2-      Nervous System:

                                             The system which controls our each and every activity is called the nervous system. This system is made up of the brain, the spinal cord and nerves. The brain is the most important part of our body. It tells the body how to work. Our brain is very delicate. The bony skull protects it from injuries. The spinal cord and nerves connect all the parts of our body to the brain.

“It is because of our brain that we can read, write, learn new things and feel hot or cold.”

3-      Breathing System (Respiratory System):

                                          We need air that contains oxygen to stay alive. Our breathing system helps to take air into the lungs and send air out of the body. Our breathing system consists of nose, windpipe and lungs.

                                    Nose filters and warms the air. The air passes through windpipe and enters the lungs. Blood takes oxygen from the lungs and carries it to all parts of the body. The lungs breathe out to use air.

“Our lungs work very hard. Every day we take about 23,000 breaths!”

4-      Circulatory System:

                                             Blood flows around our whole body through the circulatory system. This system consists of heart, veins and arteries. Our heart pumps the blood each time it beats. It pumps the oxygen rich blood into arteries. Arteries spread the blood throughout the body. Veins bring the used blood back to the heart.

“Our heart is about the size of our fist.”

5-      Digestive System:

                                              Our digestive system helps us digest the food. Digestion means to break down food into simple form. Our digestive system consists of the mouth, food pipe, stomach and intestines.

                                             We chew food in the mouth. Then it moves into the stomach through food pipe. From here the food goes into the small intestine and then into the large intestine. The blood takes food from the walls of small intestine and carries it to all parts of the body. Water is absorbed in the walls of our large intestine.

“Our liver also helps in the process of digestion.”
