The 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.

Total amount of air your lungs can hold the average total lung capacity is 6 litres of air.

# data[].attributes.body
The amount that is left in your lungs after exhaling. There needs to be air left in the lungs this is so that the lungs do not collapse.

# data[].attributes.body
Vital capacity is the amount you breathe out after you have breathed in the most you can the average for this is between 3 - 5 litres. It really depends on a lot of factors though these include height weight and

# data[].attributes.body
The most amount of air you can breathe. The average for a man is 3,100 ml and the average for a woman is 2,400 ml

# data[].attributes.body
The amount you breathe out when breathing normally

During expiration or exhalation the inner intercostal muscles contract bringing the ribs back to the original position and the diaphragm is also raised back. This reduces the space in the chest cavity and increases the pressure. This pushes the air out of the lungs.

# data[].attributes.body
During inspiration, the outer intercostal muscles contract which raises the chest cavity or the ribs. This is accompanied by the lowering of the diaphragm. Together these movements increase the size of the thoracic cavity which reduces the pressure. The air from outside rushes into the lungs.

# data[].attributes.body
Intercostal muscles are a group of muscles that run between the ribs and help move the chest. They will expand and contract this facilitates breathing

The diaphragm is a dome shaped muscle that separates the thorax from the abdomen. It's job is to inflate and deflate the thoracic cavity during inhalation. It lies at the bottom of the thoracic.

The diaphragm separates the thoracic cavity, containing the heart and lungs, from the abdominal cavity and performs an important function in respiration. as the diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs.

lobes
there are three lobes in the right lung and 2 in the left they remove carbon dioxide from the air and help put oxygen into the blood

Pleural membrane
allows the lungs to move without any friction from other organs

Pleural cavity
pleural cavity is the space between the pleura.

Both pleural cavities and membranes line the outside of the lungs as well as the inside of the chest wall.

Thoracic cavity
The thoracic cavity is the chamber in the body that protects the vertebrae

pleural fluid
is the build up of fluid between layers in the pleura

aveoli
Alveoli are an important part of the respiratory system whose function it is to exchange oxygen and carbon dioxide molecules to and from the bloodstream. These tiny, balloon-shaped air sacs sit at the very end of the respiratory tree and are arranged in clusters throughout the lungs.

# data[].attributes.body
This is the main passage way to the lungs and is a tubular system

Bronchi are the main passageway into the lungs. The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. These passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange in the respiratory system.

The Bronchi are made up of cartilidge a mucosal lining and smooth muscle. It has the cratilidge to stop it from collapsing as there is a lot of pressure going through the bronchi so it needs support. The mucosal lining stops foreign bacteria from coming into the lungs. The smooth muscle is so that the airway can narrow and expand it does this involuntarily.

The larynx is also known as the voice box and is located next to the pharynx it is responsible for producing sound
tube-shaped organ in the neck that contains the vocal cords. The larynx is about 5 cm long. It is located between the pharynx and the trachea. ... Air from the lungs is forced between them and makes them vibrate, producing the sound of a voice.

The pharynx chamber serves both respiratory and digestive functions. Thick fibres of muscle and connective tissue attach the pharynx to the base of the skull and surrounding structures.

The Epiglottis is a flap made of elastic cartridge that is attached to the larynx it opens when breathing in and allows air and and closes when not breathing in

The nasal cavity is he inside of your nose it produces mucus to keep the nose moist it also has hairs to help filter dirt. These hairs are also responsible for warming the air that you inhale so it is at a better temperature for the body.
