The Respiratory System By Katie Egan

THE RESPIRATORY SYSTEM CONTAINS MULTIPLE ORGANS THAT WORK TO TAKE IN (INHALE) OXYGEN AND GET RID OF (EXHALE) CARBON DIOXIDXE.

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

Trachea

  • 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

Lungs

  • 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

Diaphragm

  • 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

Epigilottis

  • 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

  • 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
