Respiration is something else than breathing. Breathing is the ventilation of air in your lungs. Respiration is the process where oxygen is absorbed in the blood en carbon dioxide is discharged through the blood.
- Oxygen = Zuurstof
- Carbondioxide= Koolstofdioxide
- Respiration = Gaswisseling
- Breathing = Ademhalen
- Larynx/Voice box= Strottenhoofd hier liggen je stembanden.
- moistened= bevochtigt
- cilia= Trilharen
- Pharynx = Keelholte
- Trachea= Luchtpijp
- Bronchioles= Bronchiolen/Vertakkingen van de bronchieen
- Cartilage= Kraakbeen
- Alveoli= Longblaasjes
- capillaries= Haarvaten
- Metabolism= Stofwisseling
- Nostrils= Neusgaten
- Epiglottis= Strotklepje
The trachea (or windpipe)The trachea (or windpipe) is a wide, hollow tube that connects the larynx (or voice box) to the bronchi of the lungs. It is an part of the body’s airway and gives air flow to and from the lungs for respiration.
The trachea begins at larynx in the neck. It is located in front of the esophagus it is just under the skin of the neck so you can feel the trachea.
The trachea is full of millions of cilia. When you breath in most dust particles are trapped in your nasal hair. However a lot of particles still manage to get in, if you breath from your mouth then even more get in. The trachea is covered in sticky mucous and as air enter the trachea the particles of dust, dirt, microbes and even airborne bacteria stick to the mucous. The cilia's function is like to sweep the mucous up to the top of the trachea. Once reaching the top, the mucous is swallowed where the acid of the stomach kills any bacteria.
What are the bronchi
Bronchi are the main passageway into the lungs. When someone takes a breath through his nose or mouth, the air travels into the larynx. The next step is through the trachea, which carries the air to the left and right bronchus. The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. These passageways then become tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange in respiratory system. There is no gas exchange with the blood in any of the bronchi, it is only for transport of air.
