CAPILLARIES are blood vessels in the walls of the alveoli. Blood passes through the capillaries, entering through your PULMONARY ARTERY and leaving via your PULMONARY VEIN. While in the capillaries, blood gives off carbon dioxide through the capillary wall into the alveoli and takes up oxygen from air in the alveoli.The right lung has 3 sections called lobes and is a little larger than the left lung, which has 2 lobes. 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.About 78 per cent of the air is nitrogen and 21 per cent is oxygen. These two gases can be separated by fractional distillation of liquid air.

How do lungs filter oxygen from other gases?
The right lung has 3 sections called lobes and is a little larger than the left lung, which has 2 lobes. 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.
How is oxygen separated from the air we breathe?
About 78 per cent of the air is nitrogen and 21 per cent is oxygen. These two gases can be separated by fractional distillation of liquid air.

How do the lungs get rid of all the CO2 they’ve picked up from the blood?
Carbon dioxide (CO2) is a waste product of cellular metabolism. You get rid of it when you breathe out (exhale). This gas is transported in the opposite direction to oxygen: It passes from the bloodstream – across the lining of the air sacs – into the lungs and out into the open.
What separates the lungs from each other?
Each lung is divided into lobes by fissures. Both lungs have oblique fissure and the right is further divided by a transverse fissure. The oblique fissure in the left lung separates the superior and the inferior lobe. The oblique and horizontal fissure divides the lungs into superior, middle and inferior lobes.
How do the lungs work step by step?
When you inhale (breathe in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out). This process, called gas exchange, is essential to life.
Where in the lungs does gaseous exchange take place?
ALVEOLI are the very small air sacs where the exchange of oxygen and carbon dioxide takes place. CAPILLARIES are blood vessels in the walls of the alveoli.
How do you separate gases?
Pure gases can be separated from air by first cooling it until it liquefies, then selectively distilling the components at their various boiling temperatures. The process can produce high purity gases but is energy-intensive.

How Your Lungs Work – Cleveland Clinic
Your lungs make oxygen available to your body and remove other gases, such as carbon dioxide, from your body. This process takes place 12 to …
Exchanging Oxygen and Carbon Dioxide – Merck Manuals
Three processes are essential for the transfer of oxygen from the outside air to the blood flowing through the lungs: ventilation, diffusion, and perfusion.
Every breath you take: the process of breathing explained
One gas (oxygen) is exchanged for another (carbon dioxide). This exchange of gases takes places both in the lungs (external respiration) and …
How do lungs work? – InformedHealth.org – NCBI Bookshelf
The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in …
How do you separate oxygen substances?
- Substance 1 Oxygen- cannot be separated.
- Substance 2 Water- can be separated into hydrogen and oxygen by the electrolysis process that uses electricity.
- Substance 3 Gold- cannot be separated.
- Substance 4 Carbon Dioxide- can be separated into carbon monoxide and oxygen by electrolysis process.
Is it possible to separate oxygen?
This is possible using a process known as electrolysis, which involves running a current through a water sample containing some soluble electrolyte. This breaks down the water into oxygen and hydrogen, which are released separately at the two electrodes.
How does the body convert oxygen to carbon dioxide?
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
How carbon dioxide is removed from the body?
CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation. CO2 plays various roles in the human body including regulation of blood pH, respiratory drive, and affinity of hemoglobin for oxygen (O2).
What happens to oxygen during gas exchange?
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Can you live with one 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.
What does diaphragm separate?
The diaphragm is a thin dome-shaped muscle which separates the thoracic cavity (lungs and heart) from the abdominal cavity (intestines, stomach, liver, etc.).
What is the alveoli function?
The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body.
How does oxygen travel through the body?
Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.
Can you live without lungs?
Although it is possible to live without a lung, there are a few risks involved. A study in the Journal of Cancer notes that pneumonectomy, or the surgery to remove one of the lungs, is a high risk surgery that can lead to complications and even death.
Which is the correct pathway of oxygen to the lungs?
The oxygen present in the air reaches the lungs through the upper and lower respiratory tract. Air enters the body through the nasal and oral cavity, then passes through the pharynx, larynx and trachea and then reaches the lungs.
How the oxygen is transported to the cells from the alveoli?
Answer: The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell.
How does transport of o2 and CO2 takes place in man?
Since haemoglobin pigment has less affinity for CO2, it is mainly transported in the dissolved form. This deoxygenated blood gives CO2 to lung alveoli and takes O2 in return. Around 20-25% of carbon dioxide is carried by haemoglobin as carbamino-haemoglobin.
How does alveoli help gas exchange?
Although tiny, the alveoli are the center of your respiratory system’s gas exchange. The alveoli pick up the incoming energy (oxygen) you breathe in and release the outgoing waste product (carbon dioxide) you exhale.
How do you separate CO2 from other gases?
CO2 can be separated from other gases by cooling and condensation. Cryogenic separation is widely used commercially for streams that already have high CO2 concentrations (typically >90%) but it is not used for more dilute CO2 streams.

Which separation technique can be used to separate the gases in air?
Answer: To Obtain Different Gases from Air. Air can be separated into components by fractional distillation.
What is the process of separation of components of air?
Air is a homogeneous mixture of different gases such as oxygen, nitrogen, carbon dioxide, etc. It can be separated by the process of fractional distillation.
