Organs
This organ expands when oxygen is inhaled and deflates when carbon dioxide is released
What are the lungs?
This organ is one of the entrances to the respiratory system and lets air in from your external environment without cleaning it
What is the mouth?
State the function of the larynx
What is the larynx allows us to talk when vocal cords open and close to make sounds?
The purpose of inhaling is...
What is to breathe in oxygen for the body to use?
The respiratory system gives oxygen directly to what other system that transports it around the body for us
What is the circulatory system?
This structure transports air, food, and water because it contains parts of both the trachea and esophagus
What is the pharynx?
This structure is also known as the voice box and contains your vocal cords that are stretched across the opening of it
What is the larynx?
State the function of the capillaries
What is the capillaries are blood vessels that allow the exchange of oxygen and carbon dioxide? What is oxygen enters the bloodstream and carbon dioxide exits the bloodstream through capillaries?
The purpose of exhaling is...
What is to get rid of carbon dioxide when we breathe out?
The scientific name for the process of breathing
Respiration
Very small blood vessels that surround the alveoli
What are capillaries?
This passageway, covered in cartilage for protection, carries air from your throat to your lungs
What is the trachea?
State the function of the nasal passageway/nose
What is the nasal passageway/nose allows the air we breathe to be cleaned with hairs and warmed before entering our lungs?
Why are capillaries important to the respiratory system
What is they are the means by which oxygen is given to the bloodstream to be transported around the body?
All of our body systems need what in order to function that they can only get from the respiratory system
What is oxygen?
These tubes split into two from the trachea, with one tube going to each lung. They then split into even tinier tubes that lead to the alveoli
What are the bronchial tubes/bronchi?
This organ, which contains hair and mucus, is one of the entrances to the respiratory system
What is the nasal passage/nose?
State the function of the diaphragm
What is the diaphragm contracts (moves down) to let the lungs inflate when inhaling oxygen and relaxes (moves up) to let the lungs deflate when exhaling carbon dioxide?
State the purpose of glucose in our respiratory system
What is to combine with oxygen to give us energy?
Carbon dioxide and what else is removed from our body when we exhale
What is water?
These structures are tiny air sacs in the lungs that are surrounded by capillaries
What is the alveoli?
A dome-shaped muscle found below the lungs that helps with breathing
What is the diaphragm?
State the function of the alveoli
What is the alveoli allows oxygen and carbon dioxide to be exchanged between the respiratory system and the circulatory system? What is alveoli allows oxygen to enter the bloodstream and carbon dioxide to be released from the bloodstream?
State what cellular respiration is
What is oxygen reactions with the sugar (glucose) in food to make energy for our body?
Besides allowing us to breathe, what TWO other purposes does the respiratory system have
What is smelling and speaking?
