Human Respiratory System- Facts and Information

Human Respiratory System

From the moment a child is born, a baby is breathing. We all breathe in and out with the help of our nose. Each living organism, from a unicellular organism to multi-celled organisms, undergoes respiration and Human Respiratory System.

What Is Respiration?

Respiration is a vital metabolic process that takes place in all living species, including plants, animals, birds, insects and Human Respiratory System, for their survival. Our body demands oxygen to obtain energy to fuel all our living processes. Breathing is a fundamental part of the respiration process and every cell of the body requires oxygen. Before moving into the exciting facts about the respiratory system, let us glance at the respiratory system parts, functions and respiration process.Respiration is the process through which the food we eat is converted into valuable energy. As we all know, every single cell requires energy to perform its functions. Therefore, respiration that takes place at the minor level of our body is called cellular respiration. We all have a developed and complicated respiratory system.

The Human Respiratory System is the network of organs and tissues, which include: nose, lungs, nasal chambers, larynx, pharynx, trachea, alveoli, epiglottis and bronchioles.

Facts About The Human Respiratory System

Here are few fascinating facts about the Human Respiratory System.

Fact-No- 1

Lungs are the significant organ of the Human Respiratory System. Human Respiratory System have a pair of lungs, which has a total capacity of 6 litres.

Fact-No- 2

The right lung is more significant than the justify lung. The surface area of both lungs is similar to the size of a tennis court.

Fact-No- 3

When we inhale or breathe in, we inhale a minimal amount of air. The oxygen composition in the air is 21%, but our body requires only 5% of it.

Fact-No- 4

Both the lungs and windpipe work together in supplying oxygen to the tissues and cells of the body.

Fact-No- 5

Inhalation is much stronger than exhalation, while exhalation takes longer than inhalation.

Fact-No- 6

It is always preferred to breathe (inhale and exhale) through the nose than from the mouth. This is because the air we breathe in is filtered in four stages and is followed by our nose.

Fact-No- 7

Our body is constantly losing water every time we breathe. On average, we lose about 1 cup or 12 oz. of water each day just from breathing.

Fact-No- 8

Breathing through the mouth results in ear infections, tonsillitis, sore throats, and other disorders.

Fact-No- 9

Slow breaths help in increasing our lifespan. An average person breathes eighteen  to twenty thousand times a day.

Fact-No- 10

The rate of breathing is faster in children and women than in men.

Fact-No- 11

As per the experts, our appetite depends on our style of breathing.  Yes, it is true. As we take deep breaths and inhale more oxygen, more oxygen is supplied to our cells and the process of breakdown of food speeds up and we feel hungrier.

Fact-No- 12

Inhaling and exhaling through the mouth disrupt the oxygen and carbon dioxide balance in our lungs, which lead to consequences.

Fact-No- 13

According to the research, yawning assists us to take more oxygen into our blood cells and remove more carbon dioxide out of the blood.

Fact-No- 14

Yawning is a primarily involuntary process, which is brought out by opening the mouth and breathing in deeply. The brain sends a message to the sensory system to take a long deep breath or a yawn when it senses the scantiness of oxygen.

Fact-No- 15

There are different chronic infectious diseases caused by bacteria, fungi and other microbes. These infectious diseases include Pneumonia, bronchitis, tuberculoid leprosy and different types of leprosy. These diseases are transmitted from the nose, mouth and mainly affects the mucous membrane of the upper respiratory tract. These infections can lead to damage of the nerves, respiratory tract and other parts of the body, followed by severe symptoms.
