The common cold can be caused by hundreds of different viruses.
Your nose is a filter, heater and a humidifier.
Coughing, sneezing and yawning are natural mechanisms.

What is the structure and function of the lungs?
The lungs are like bellows. As they expand, air is sucked in for oxygen. As they compress, the exchanged carbon dioxide waste is pushed back out during exhalation. When air enters the nose or mouth, it travels down the trachea, also called the windpipe.
What is the power of lungs write about it?
The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.
What are 10 interesting facts about muscles?
Fun Facts About the Muscular System You Didn’t KnowMuscles are divided into three types: smooth, cardiac, and skeletal. … Your body contains more than 600 muscles. … Muscles are made up of special cells called muscle fibers. … The largest muscle in the body is the gluteus maximus.More items…•
Do lungs float in water?
The lungs are the only organ in the body that can float on water. The lungs produce a detergent-like substance which reduces the surface tension of the fluid lining, allowing air in.
Can you live with one lung?
In most cases, one healthy lung should be able to deliver enough oxygen and remove enough carbon dioxide for your body to stay healthy. Doctors call the surgery to remove a lung a pneumonectomy. Once you’ve recovered from the operation, you can live a pretty normal life with one lung.
What is the importance of respiratory system?
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
What are 3 interesting facts about the respiratory system?
Gasp! 11 Surprising Facts About the Respiratory SystemSurprise! … You lose a lot of water just by breathing. … Some people can hold their breath for more than 20 minutes. … The lungs are the only organs that can float on water. … Sneeze particles may not travel as fast as people think. … The common cold can be caused by hundreds of different viruses.More items…•
How do we breathe automatically?
The rate and depth of breathing is automatically controlled by the respiratory centers that receive information from the peripheral and central chemoreceptors. These chemoreceptors continuously monitor the partial pressures of carbon dioxide and oxygen in the arterial blood.
How many lungs do we have in our body?
Your lungs are in your chest, and are so big that they take up most of the space in there. You have two lungs, but they aren’t the same size the way your eyes or nostrils are. Instead, the lung on the left side of your body is a bit smaller than the lung on the right.
What is the most important muscle in the respiratory system?
diaphragmThe diaphragm, a dome-shaped sheet of muscle that separates the chest cavity from the abdomen, is the most important muscle used for breathing in (called inhalation or inspiration). The diaphragm is attached to the base of the sternum, the lower parts of the rib cage, and the spine.
What are the functions of lungs?
Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system’s main job is to move fresh air into your body while removing waste gases.
What muscles do we use to breathe?
Diaphragm, which is a dome-shaped muscle below your lungs. It separates the chest cavity from the abdominal cavity. The diaphragm is the main muscle used for breathing. The muscles between your ribs, called intercostal muscles, play a role in breathing during physical activity.
What is the major organ of the respiratory system?
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
