Take a breath and let’s find out about our Respiratory System!!
What is the respiratory system?
A system designed to deliver oxygen to the body and to get rid of carbon dioxide.
Organs in the Respiratory System:
- Nasal cavity
Looking at the organs more in depth:
- Pharynx – a passage that leads from the cavities of the nose and mouth to the larynx and esophagus. Air passes through the pharynx to our lungs, and food enters the esophagus through the pharynx.
- Larynx – is located between the pharynx and the trachea. It is surrounded by walls or cartilage and muscle, and the home to our vocal cords.
- Bronchi – are large air tubes leading from trachea to the lungs that pass on air to and from the lungs.
- Lungs – a pair of breathing organs located with the chest to remove carbon dioxide from and bring oxygen to the blood. We a right and left lung.
- Nasal Cavity – a cavity on either side of the nasal septum( the middle bone in our nose) and lies between the floor of the cranium(bone on top of our brain) and the roof our mouth
- Epiglottis – an elastic like structure located at the roof of our tongue that over the glottis to prevent food and liquid from entering the trachea during swallowing.
- Diaphragm – a large muscle that separates the chest from the abdomen. This is the principle muscle of respiration. When the diaphragm closes in and moves down, the lungs expand and air moves in to them. As the diaphragm relaxes and moves up, the lungs close in and air is forced out.
