Science(Respiratory and Circulatory) Reviewer Flashcards
is what we normally use to inhale and exhale. It has two holes called nostrils through which air passes. The skin lining both nostrils is embedded with tiny hairs called cilia, which act like a filter to catch dust and other small particles in the air we breathe.
Nose
is the opening just behind the nose and
mouth and is part of both the respiratory and digestive systems. Both food and
air pass through it
Pharynx
is also known as the “voice box” because it houses the vocal chords and the different muscles used in producing sounds. The epiglottis, a cartilage found at the top of the larynx, aids in closing it tightly to prevent the passage of food or liquids.
Larynx
also referred to as the windpipe, is a tube through which respiratory gas transport takes place
Trachea
The end of the trachea is split into two tubes called the bronchi, which also have several thin-walled branches called bronchioles. These ______ lead to air sacs called alveoli, where most of the gas
exchange happens

Singers use their ______ instead of the throat to improve the quality of their voice
diaphragm
Singers use their ______ instead of the throat to improve the quality of their voice
diaphragm
_____ are the most difficult organ to transplant because they are highly susceptible to infections
Lungs
is to transport oxygen and nutrients to the body cells
and to carry deoxygenated (oxygen-poor) blood and
carbon dioxide back to the heart and lungs
