7.1 Flashcards
What are two main requirements
for respiration.
surface area for gas exchange and moisture so 0xygen and carbon can be dissolved in water
breathing in and breathing out are called
inspiration and expiration
the nasal passage is lined with what and what are there function.
mucus traps and clean air while ciliated cells moves the foreign particles back up into the nose
and throat to be expelled by coughing or sneezing. blood helps warm the air
what are turbinate bones in the nasal cavity.
increasing the surface area of the nasal passages. They are covered in cilia
The pharynx?
pathway of both air and food intersect
epiglottis?
closes over the opening to the trachea
glottis?
opening to the trachea
larynx?
made from cartilage and contains the vocal
cords.
trachea?
strengthened by
semicircular, cartilaginous arches that prevent it from collapsing.
bronchi?
when The trachea branches into two smaller passageways
bronchioles?
Each bronchus subdivides many
times to create a branching network
of smaller and finer tubes,
what are the sim and difference of bronchi and bronchioles
sim- lined with cilia and mucus cells
diff- bronchi has the c-shaped cartillage, other docent.
what are lobes and how many are in each lung
lobes are distinct regions in the
lung. right has 3, left has 2
pleural membrane?
Each lung is surrounded by a thin,
double-layered membrane. Fluid fills the space between these two
membrane layers for connecting the lungs to the thoracic cavity, enabling them to expand and contract with the movement of the chest.
alveoli?
is where gas exchange happens
How are The arrangement of the bronchioles and alveoli, kept in a relatively permanent position
by elastic connective tissue that fills the space between them. As well, the alveoli are lined with a lubricating film that helps to keep them from collapsing and prevents their sides
from sticking together and closing.
