The Respiratory System By Katie Egan

Major Organs that make up the Respiratory System: trachea, lungs, diaphragm, epiglottis, larynx, and vocal cords


  • Also known as your wind pipe
  • Runs from your larynx to the bronchi in the lungs, connecting them
  • Very important because it provides space for air to flow to and from your lungs
  • Made of cartilage- a soft bony material
  • It later changes into bone as it ages
  • It is located right in front of the esophagus


  • Trachea splits into two bronchi to supply air for your left lung and right lung.
  • The bronchi divide and divide until they are multiple small, hollow tubes called bronchioles
  • Alveoli are located at the end of each bronchus. There are capillaries surrounding the alveoli where oxygen is converted into carbon dioxide.
  • Lungs mainly function by taking and making sure the oxygen you breathe in gets to your red blood cells


  • A muscle that is shaped like a parachute and is located below the lungs
  • When you inhale, the diaphragm┬ácontracts while your chest expands
  • Because of this, air is sucked in by a created vacuum
  • When you exhale, the diaphragm expands while your chest contracts
  • Because of this, the air is released


  • It is a flap between the larynx and esophagus that opens and closes to permit air and food to pass down the esophagus

Vocal cords

  • They are little flaps of muscle that vibrate and close to make sound
  • Located in the larynx

Breathing pRocess:

  • First, you inhale oxygen by nose or mouth
  • It then travels down your trachea into the bronchi of the lungs
  • It reaches the alveoli at the end of the bronchi
  • The capillaries surrounding the alaveoli convert the oxygen into carbon dioxide
  • Your blood absorbs the oxygen and travels to the heart which then supply's the other organs and tissues with it
  • The carbon dioxide is produced in the blood, transported back to the lungs, and eventually exhaled.

Fun Facts ­čśÄ

  • Women and children have a higher breathing rate than men
  • A tennis court is roughly the same size as your lungs' surface area
  • If placed end to end, the capillaries at the end of the alveoli would extend 1,600 kilometers long (or around 994 miles)
  • The only organs that can float on water are the lungs
  • In ancient Egypt, the trachea and lungs were depicted on hieroglyphics, representing Upper and Lower Egypt


  • Asthma is a disease associated with the Respiratory System
  • It is a disorder of the lungs that causes wheezing, chest tightness, coughing, and breathlessness
  • Symptoms are anywhere from mild to life threatening
  • 7-10% of children have asthma
  • 7-9% of adults have asthma

Ways to preVent it

  • Medicine is the primary way to treat asthma; such as an inhaler
  • There are no ways to cure it, but just ways to prevent it
  • Always try to get to a doctor when you first see symptoms

How the respiratory system works with the digestive sYstem

  • Both systems use the esophagus
  • The respiratory system needs the digestive system because in order for you to inhale, your diaphragm and muscles need fuel which come from the efforts of the digestive tracts
  • The digestive system needs the respiratory system because the digestive muscles that break down food need oxygen to survive
