The primary function of the lung is the exchange of gases between the body and the environment . The lungs contain a series of narrowing passageways that terminate into tiny sacs called alveoli. During respiration, oxygen enters the lungs by diffusion through the capillaries surrounding each alveolar sac.
What is lungs and its function?
What do the lungs do? The lungs' main function is to help oxygen from the air we breathe enter the red cells in the blood . Red blood cells then carry oxygen around the body to be used in the cells found in our body. The lungs also help the body to get rid of CO 2 gas when we breathe out.
What is the structure 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.
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 function of lungs in our body?
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.
How many parts are in the lungs?

Which lung is the largest?
The right lung is larger and weighs more than the left lung. Since the heart tilts to the left, the left lung is smaller than the right and has an indentation called the cardiac impression to accommodate the heart.
Why do we have 2 lungs?
In the case of lungs, evolution has selected for a certain quantity of lung capacity to meet a range of oxygen needs of the body. A secondary consideration is how to organize lung tissue. There is a certain advantage to dividing lung tissue equally across both sides of the body vs. having all lung tissue on one side.
What is the function of left lung?
According to York University, the right lung is shorter because it has to make room for the liver, which is right beneath it. The left lung is narrower because it must make room for the heart . Typically, a man's lungs can hold more air than a woman's.
Where is lungs in our body?
The lungs are located on either side of the breastbone in the chest cavity and are divided into five main sections (lobes). The lungs are responsible for removing carbon dioxide from the blood and adding oxygen to it. The heart and lungs work together to do this.
What are the 7 organs of respiratory system?
- Nose.
- Mouth.
- Throat (pharynx)
- Voice box (larynx)
- Windpipe (trachea)
- Large airways (bronchi)
- Small airways (bronchioles)
- Lungs.
Which cavity is present in lungs?
The lungs are housed in the chest cavity , a space that also includes the mediastinum.
What are the organs of respiratory system?
The main organ of the respiratory system is the lungs . Other respiratory organs include the nose, the trachea and the breathing muscles (the diaphragm and the intercostal muscles).
Do lungs help blood get around your body?
Blood with fresh oxygen is carried from your lungs to the left side of your heart, which pumps blood around your body through the arteries . Blood without oxygen returns through the veins, to the right side of your heart.
Where is lung pain felt?
The lungs do not have a significant amount of pain receptors, which means that any pain felt in the lungs probably originates somewhere else in the body. However, some lung-related conditions can result in pain in the left lung . The chest contains several vital organs, including the heart and lungs.
What are the 5 main 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.
