RESPIRATORY SYSTEM

Airways We never really think about breathing because it is such an automatic process, but it is vital to our survival. Every inward breath brings a new supply of air into the network of tubes that make up the respiratory system

WOW! Every day you swallow about a glassful of slimy mucus produced by your airways

The respiratory systemYour lungs and the airways that carry air in and out of your body are located in your head and chest. The airways include the nasal cavity, the throat, the larynx and the branching passages inside the lungs

Oxygen supply We breathe in oxygen(O2) and breathe out waste Carbon dioxide(CO2). So why doesn't our oxygen supply run out? Plants ensure there is a steady supply in the air by releasing oxygen during photosynthesis, the process that uses sunlight and carbon dioxide to make food

This way to the lungs The ridged appearance of the windpipe is produced by rings of rubbery cartilage that hold it open during breathing and stop it from closing up

In and out Our body cells need constant supplies of oxygen. They also need to get rid of waste carbon dioxide gas. This exchange of gases happens in your lungs.

What is air ?Air is a mixture of gases that surrounds our planet. In a balloon diagram, air is mostly nitrogen (about 78 per cent) and oxygen (about 21 per cent), plus small amounts of other gases

Nasopharynx The nasopharynx is, by definition, the upper part of the throat behind the nose. It is the part of the pharynx, which comprises 3 sections, the nasopharynx is one of them.

Oropharynx The oropharynx is the part of the throat at the back of the mouth behind the oral cavity. It includes the back the third back of the tongue, the soft palate, the side and back walls of the throat, and the tonsils

Nasal cavity The nasal cavity is the inside of the nose. It is lined with a mucous membrane that helps to keep the nose moist by making mucus so you won't get nosebleeds from a dry nose

Larynx The larynx (voice box) is part of the respiratory system that holds the vocal cords. It is responsible for producing voice, helping us swallow and breathe

Epiglottis The epiglottis is the area of the larynx that holds the vocal cords. It also houses the vocal folds and the spaces between them. The epiglottis helps with the creation and development of human speech

Trachea (windpipe) The trachea begins immediately below the larynx (voice box) and runs down the Center of the front part of the neck and ends behind the upper part of the sternum

Bronchus The lungs tertiary bronchus are also called the segmental bronchus. They branch out from the secondary bronchus, which descend from the mainstream bronchus. Each tertiary bronchus serves a particular bronchopulmonary

Lungs The human lungs are a pair of large, spongy organs optimized for gas exchange between our blood and the air. Our body's need oxygen in order to survive. The lungs provide us with that vital oxygen

Diaphragm The diaphragm in the respiratory system is a dome shaped sheet of muscle that separates the chest and abdomen. It is also referred to the thoracic diaphragm because it's located in the thoracic cavity

HypopharynxThe hypopharynx extends from it's juncture with the oropharynx at the tip of the epiglottis(or level of the hyoid bone) superiorly to the inferior border

Laryngopharynx The laryngopharynx is where both food and air pass
