Solution.
WHAT IS Gross anatomy
study of organs and structures visible to the naked eye
The lung that has 3 lobes?
right lung
What is Hilum
root of lung, where pulmonary vessels and bronchi enter each lung
The three main portions of the respiratory system
conducting portion, filtration portion, respiratory portion
What are the major aspects of the conducting portion
nostrils, pharynx, larynx, trachea, bronchi, bronchioles
Name the major aspects of the filtration portion
nostrils (hair and mucous), trachea and bronchi (mucous and cilia)
Name major aspects of the respiratory portion
respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli
What is pleura
membranes that cover the lungs and surrounding tissues
functions of pleura
facilitate movement of lungs, enclose lungs and pleural cavity, reduce friction and
create negative pressure environment
Function of visceral pleura?
covers the lungs
The role of parietal pleura?
covers surfaces surrounding the lungsa
Function of pleural space
helps to pull open the lungs, normally empty except for a small amount of healthy
fluid
Name 3 main functions of the respiratory system (anatomical organization)
air conduction, air filtration, exchange of gases aka respiration
Name parts of the pharynx
nasopharynx, oropharynx, laryngopharynx
Function of nasopharynx
connects to the nasal cavity
oropharynx
behind the oral cavity and in front of the epiglottis
laryngopharynx
both food and air pass through, where the pharynx, larynx and esophagus meet
Function of eustachian tubes
, BIOD 151 Module 2 Exam Questions and Correct Answers 2024
connect the nasopharynx to each middle ear
Function of nasal conchae
responsible for warming and moistening air
what is needed to avoid aspiration when swallowing
the larynx rises and the epiglottis retreats back and down closing the entrance to
the trachea
why does the soft palate raise when swallowing
prevents food or liquid from entering the nasal cavity
what is the glottis
an entrance to the larynx where the vocal cords exist
major histology type found in the respiratory system
ciliated pseudo-stratified columnar epithelium
what is the bottom of the epithelium in the respiratory tract called?
basement membrane
why are the cells called "columnar"?
they are taller than they are wide
where can you find stratified squamous epithelium
vestibule of nose
pulmonary surfactant
lines the alveoli and keeps them open
Lamina Propria
very base of basement membrane
Type 1 alveolar cells
95% of alveolar epithelium, forms thin simple squamous layer, where gas
exchange occurs
Type 2 alveolar cells
produce and secrete pulmonary surfactant, can divide to replace type 1 cells
alveolar macrophages
NOT a true alveolar cell, digest bacteria and migrate toward cilia to be
expectorated
histology
study of cellular anatomy of tissues
what cell is most abundant in the alveoli
alveolar macrophages
where do air and food pass thorugh?
oropharynx
which tracheal cartilages are paired
arytenoid and corniculate
Tracheal cartilages which are singular
thyroid, epiglottis, cricoid
