What is the structure and function 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.
What is the structure and function of the lungs?
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.
What are the 5 major functions of the respiratory system?
There are five functions of the respiratory system.
- Gas Exchange – oxygen and carbon dioxide.
- Breathing – movement of air.
- Sound Production.
- Olfactory Assistance – sense of smell.
- Protection – from dust and microbes entering body through mucus production, cilia, and coughing.
What is the main function of the respiratory system?
Lung Health & Diseases
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 are the two components of the respiratory system?
The respiratory tract has two major divisions: the upper respiratory tract and the lower respiratory tract. The organs in each division are shown in Figure 16.2. 2. In addition to these organs, certain muscles of the thorax (the body cavity that fills the chest) are also involved in respiration by enabling breathing.
What is the main function of lungs?
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 the components of the lungs?
Summary Each lung is divided into lobes. The bronchial tree running through your lungs is made up of the windpipe, bronchi, bronchioles, and alveoli.
What are the features of the lungs?
The major features of the lungs include the bronchi, the bronchioles and the alveoli. The alveoli are the microscopic blood vessel-lined sacks in which oxygen and carbon dioxide gas are exchanged.
What are the 10 parts of the respiratory system?
These are the parts:
- Nose.
- Mouth.
- Throat (pharynx)
- Voice box (larynx)
- Windpipe (trachea)
- Large airways (bronchi)
- Small airways (bronchioles)
- Lungs.
What are the 7 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.
What are 10 facts about the respiratory system?
10 Surprising Facts about the Respiratory System
- The lungs are the only organs that can float on water. …
- Your lungs are not sterile or germ-free, even in health. …
- The common cold can be caused by hundreds of different viruses. …
- Your nose is a filter, heater and a humidifier.
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.
What are the 8 structures and organs of the respiratory system?
These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.
What are the types of respiratory system?
Respiratory organs of vertebrates
There are three major types of respiratory structures in the vertebrates: gills, integumentary exchange areas, and lungs.
What are the three functions of the lungs?
The most important function of the lungs is to take oxygen from the environment and transfer it to the bloodstream.
…
Respiratory disease
- asthma.
- cystic fibrosis.
- acute respiratory distress syndrome.
- chronic obstructive pulmonary disease (COPD), including emphysema and chronic bronchitis.
What are the 5 main functions of the respiratory system?
There are five functions of the respiratory system.
- Gas Exchange – oxygen and carbon dioxide.
- Breathing – movement of air.
- Sound Production.
- Olfactory Assistance – sense of smell.
- Protection – from dust and microbes entering body through mucus production, cilia, and coughing.
What type of cells are found in the lungs?
The lungs contain many different types of cells. Most cells in the lung are epithelial cells. Epithelial cells line the airways and make mucus, which lubricates and protects the lung. The lung also contains nerve cells, hormone-producing cells, blood cells, and structural or supporting cells.
What are the characteristics of a healthy lungs?
When Lungs Are Healthy
Healthy lungs look and feel like sponges. They’re pink, squishy, and flexible enough to squeeze and expand with each breath. Their main job is to take oxygen out of the air you breathe and pass it into your blood.
What characteristics would a lung cell need?
Gas exchange in the lungs
- they give the lungs a really big surface area.
- they have moist, thin walls (just one cell thick)
- they have a lot of tiny blood vessels called capillaries.
What is the scientific name of lungs?
Medical terms related to the lung often begin with pulmo-, from the Latin pulmonarius (of the lungs) as in pulmonology, or with pneumo- (from Greek πνεύμων « lung ») as in pneumonia.
What are the parts of lungs?

11 Surprising 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.
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.
What can I learn 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.
