bronchioles & alveoli
100
Name two places where air enters the respiratory system.
The mouth and nose (nasal cavity)
100
The passage that leads from the cavities of the nose and mouth?
What is food and air
100
The two gasses that are exchanged during respiration.
What is oxygen (O2) and carbon dioxide (CO2)
100
What is Trachea
A hollow tube that connects the Larynx to the right and left bronchus.
100
What is a Bronchioles
The smallest air passageways coming off the branch
200
Describe the location and composition of the windpipe (trachea)
It is located beneath the throat (pharynx) and it is made of cartilage rings or tubes that allow air to pass to the bronchi
200
What is Pharynx
the membrane-lined cavity behind the nose and mouth connecting them to the esophagus.
200
What happens when warm air enters the body?
The air is moisten and filtered as it enters the body
200
What is Bronchus
The two major air passage ways leading to the trachea to the lungs.
200
What is a alveoli
the air sacks at the end of the gas exchange takes place
300
What is the difference between bronchi and bronchioles?
They are both branching tubes of the lower respiratory system, but bronchi are two large tubes and the bronchioles are smaller sized airways leading to the alveoli.
300
What is Larynx
A hollow muscular organ which holds the vocal cords (Voice Box) which produce sound.
300
What happens when we smoke
Carbon monoxide from the smoke and nicotine both put a strain on the heart by making it work faster
300
What is a wind pipe
What is Trachea
300
What is Oxygen in & Carbon dioxide out
What is alveoli
400
What's the relationship between cilia and infection?
More healthy, intact cilia will result in lower infection rates. Cilia sweep up the bacteria, dust, and pollen grains, preventing infection, irritation, and debris from reaching the lungs. Cilia are located in the nasal cavity AND bronchi.
400
What is Epiglottis
A flat of elastic cartilage attached to the larynx that closes when food passes through.
400
What do we breathe out
Carbon dioxide
400
What are the major passage ways of the respiratory system
What is Bronchus
400
What is a diaphragm
A sheet of internal skeletal muscle that extends across the bottom of the thoracic cavity
500
What is the epiglottis and what does it do?
It is a flap of tissue that covers the trachea during eating/drinking so food doesn't go down the wrong pipe!
500
What is A Respiratory System
A series of organs which take in oxygen and off carbon dioxide(primary function).
500
what do we breathe in
500
What are the differences between the trachea and bronchi
The trachea extends from the neck and divides into two main bronchi. Structurally similar to the trachea, the two primary bronchi are located inside the lungs. .Deeper into the lungs, each bronchus is further divided into five smaller, secondary bronchi which provide air to the lobes of the lungs
500
What is under the (heart & lungs)
What is a Diaphragm
