Transcript of Respiratory System

hi
Balloons as
lungs
The Respiratory System consists of a few parts- The nosey
nose
, the windbag
windpipe
and

the
lungs
who lunges. In each of these parts, there are obviously some other sub-parts that will be discussed later on. Although they are small, they are still incredibly important!
The Basics
Respiratory System
The Basics
A typical Respiratory system which is healthy will be able to let a human to breathe in fresh oxygen and exhale carbon dioxide and other gases that are not needed.
Remember, breathing is respiratoring in a simpler term.
Windpipe/ Trachea
Cilia- Push mucus out
Goblet cells- Make mucus
Has left and right bronchi
The Basics
Divided into nasal passages (nostrils)
Formed with cartilage
Lies on roof of mouth bone
Roof is curved and narrow
Lined with mucosa/ Snot/ Boogers
Dome shaped muscle
Located below lung
separates chest cavity from abdominal cavity
Alveoli
Looks like bunches of grapes
Capillaries surround alveoli

Group 1

Nasal Cavity
Structure:
Function:
Filters air
Hairs at nostrils to trap unwanted particles
Mucus to prevent nosebleeds
Structure:
Function:
Passageway for oxygen entering the lungs
Passageway for carbon dioxide exiting lungs
Filters particles from the air (cilia)
Lungs
Structure:
Cone-shaped
Contain all bronchi
2 lungs at the sides of breastbone
Lungs are divided into 5 lobes- right 3, left 2
Left Lung is smaller than right
Chest cavity- supports and protects lungs
Diaphragm- muscle located under lungs
Function
Main organ in Respiratory system
Respiration (breathing)
15-18 times per minute
Take in oxygen, remove carbon dioxide
Transport oxygen to blood and remove waste
Diaphragm supports and enables function
Structure:
Function:
Tiny air sacs
Primary gas exchange of the lungs
O2 passes into red blood cells
CO2 becomes waste product and removed through exhalation
Diaphragm
Structure:
Function:
Main muscle used for breathing
Breathe in/inhale- diaphragm contracts
Enlarges space available in chest cavity (Gap)
Creates negative pressure
Leads to suction force
Drawing of air into the lungs
Diseases
Types:
Bronchitis
Bronchitis is an inflammation of the mucous membranes of the bronchi
Asthma
Asthma is a common chronic inflammatory disease of the airways
Emphysema
Emphysema is a long-term lung disease. In people with emphysema, the tissues necessary to support the shape and function of the lungs are destroyed.
Bronchitis
Causes:
Solvents/ Inhalants
Haze
Smoke/ Smoking
Asthma
Causes:
Genes
Prolonged exposure to smoke/ Smoking
Stress
Pregnancy
Environmental Factors- Haze/Over-exercise
Allergies
Emphysema
Causes:
Long-term Smoking
Exposure to air pollution
Exposure to Silica dust
Exposure to Coal
Exposure to Factory Fumes
The Respiratory System
Function as a whole
Breathing (respiration) Supplies blood with oxygen
Transported throughout the body
Air flow- speech made possible
Goal: deliver oxygen, remove carbon dioxide
Divided into: Upper respiratory tract, Lower respiratory tract
Made up of: Airways, Lungs, Linked blood vessels , Muscles
Link between other Systems
Digestive System
Pharynx controls path of food, directs to stomach to be digested
Circulatory System
Oxygen transported to blood
Carbon Dioxide removed from blood

Experiment
THE END!!!
Thank you for your attention. Hope you weren't too bored. Please buy our product!
This is a picture of the
diagram of the experiment
Step 1. Pull down the rubber flap of the
set- up. The smaller balloons inside
should inflate with air.

Step 2. Let go of the rubber flap and
the small balloons should deflate
Explanation:
This is an experiment that shows how our respiratory systems work. The rubber flap below the bottle represents the diaphragm, which controls the air intake, whereas the small balloons represent the lungs that take in the the air we breathe.
