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.
How do you explain the respiratory system to a child?
The respiratory system’s main function is to supply oxygen to all the parts of your body. It does this through breathing: inhaling oxygen-rich air and exhaling air filled with carbon dioxide, which is a waste gas.
What is the main function of the respiratory system?
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 is respiratory in simple words?
1 : the act or process of breathing : the inhaling of oxygen and the exhaling of carbon dioxide. 2 : the process by which cells use oxygen to break down sugar and obtain energy.
What are 5 fun facts about the respiratory system?
- Surprise! ...
- 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.
How will you describe the pathway of oxygen in the respiratory system?
The bronchial tubes divide into smaller air passages called bronchi, and then into bronchioles . The bronchioles end in tiny air sacs called alveoli, where oxygen is transferred from the inhaled air to the blood. After absorbing oxygen, the blood leaves the lungs and is carried to the heart.
What are 3 main functions of the respiratory system?
- Allows you to talk and to smell.
- Warms air to match your body temperature and moisturizes it to the humidity level your body needs.
- Delivers oxygen to the cells in your body.
- Removes waste gases, including carbon dioxide, from the body when you exhale.
What are the 3 parts of the respiratory system?
There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration . The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body’s exterior.
What are the 6 functions of the respiratory system?
The functions of the respiratory system include gas exchange, acid-base balance, phonation, pulmonary defense and metabolism, and the handling of bioactive materials .
Where is respiratory located?
The respiratory system starts at the nose and mouth and continues through the airways and the lungs . Air enters the respiratory system through the nose and mouth and passes down the throat (pharynx) and through the voice box, or larynx.
What is respiration with example?
The process by which organisms exchange gases, especially oxygen and carbon dioxide, with the environment. In air-breathing vertebrates, respiration takes place in the lungs. ... Respiration is taking a breath or the act of breathing. An example of respiration is inhaling and exhaling air .
How do we keep the respiratory system healthy?
Tips for a healthy respiratory system
avoid harmful environmental factors such as smoke, dusts and chemicals. exercise (check with your doctor first if you have a health condition), preferably away from busy roads with high air pollution . wash your hands regularly to prevent infections . eat a healthy, vitamin-rich diet .
What is the other term used to describe respiratory system?
The respiratory system (also respiratory apparatus, ventilatory system ) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants.
How many times do we breathe a day?
Breathing is something that we all do without usually realizing it. We breathe in and out about 22,000 times a day . We are powered by breathing. Our lungs fuel us with oxygen, our body’s life-sustaining gas.
Can you live with 1 lung?
Most people can get by with only one lung instead of two, if needed. Usually, one lung can provide enough oxygen and remove enough carbon dioxide, unless the other lung is damaged. During a pneumonectomy, the surgeon makes a cut (incision) on the side of your body.
How do the lungs work step by step?
To breathe in (inhale), you use the muscles of your rib cage – especially the major muscle, the diaphragm. Your diaphragm tightens and flattens, allowing you to suck air into your lungs. To breathe out (exhale), your diaphragm and rib cage muscles relax. This naturally lets the air out of your lungs.
When you inhale your lungs inflate or deflate?
When you breathe in, your diaphragm pulls downward, creating a vacuum that causes a rush of air into your lungs. The opposite happens with exhalation: Your diaphragm relaxes upward, pushing on your lungs, allowing them to deflate .
What are the two types of respiration?
There are two types of cellular respiration (see Cellular Respiration concept): aerobic and anaerobic . One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic). Both begin with glycolysis – the splitting of glucose.
How do you remove carbon dioxide from your body?
In the human body, carbon dioxide is formed intracellularly as a byproduct of metabolism. CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation .
What are the 5 major parts of the respiratory system?
- Nose.
- Mouth.
- Throat (pharynx)
- Voice box (larynx)
- Windpipe (trachea)
- Large airways (bronchi)
- Small airways (bronchioles)
- Lungs.
What are the types of respiratory system?
There are three major types of respiratory structures in the vertebrates: gills, integumentary exchange areas, and lungs .
How are lungs connected to throat?
The TRACHEA (windpipe) is the passage leading from your pharynx to the lungs. The RIBS are bones supporting and protecting your chest cavity. They move a small amount and help the lungs to expand and contract. The trachea divides into the two main BRONCHI (tubes), one for each lung.
How does breathing occur?
Breathing in
When you breathe in, or inhale, your diaphragm contracts and moves downward . This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
What have you learned in respiratory system?
Through breathing, inhalation and exhalation, the respiratory system facilitates the exchange of gases between the air and the blood and between the blood and the body’s cells. The respiratory system also helps us to smell and create sound. The following are the five key functions of the respiratory system.
What are the 4 phases of respiration?
The respiratory cycle is divided into 4 phases: inspiration (light green), end-inspiration (dark green), expiration (light red) and end-expiration (dark red) .
What is respiration according to 10th?
RESPIRATION is the biochemical process in living organisms involving the production of energy . This is typically done with intake of oxygen and this results in the release of carbon dioxide, water, and ATP (the currency of energy in cells).
What causes lung damage?
Smoke from cigarettes, cigars, and pipes is the number one cause of lung disease. Don’t start smoking, or quit if you already smoke. If you live or work with a smoker, avoid secondhand smoke. Ask smokers to smoke outdoors.
Can you breathe without lungs?
In general, you need at least one lung to live . There is one case of a patient who had both lungs removed and was kept alive for 6 days on life support machines until a lung transplant was performed. This is not a routine procedure and one cannot live long without both lungs.
How many inhales a minute?
Respiratory rate: A person’s respiratory rate is the number of breaths you take per minute. The normal respiration rate for an adult at rest is 12 to 20 breaths per minute . A respiration rate under 12 or over 25 breaths per minute while resting is considered abnormal.
How do you exercise your lungs?
Pursed-lip breathing lung exercises are easy to do and can be done anywhere at any time. The exercise involves inhaling, slowly, through the nose and exhaling through pursed lips. The goal is to take twice as long breathing out as breathing in, so if you inhale for five seconds, you’ll want to exhale for 10 seconds.

How many times do you breathe when you sleep?
The average person takes about 14 breaths per minute while awake and 15 or 16 while asleep , Morgenthaler said. Although you breathe more frequently while sleeping, you actually take in less oxygen and push out less carbon dioxide because your body’s need for ventilation isn’t as high as when you’re awake.
