What are the 2 major respiratory division
upper respiratory tract (head & neck)
Lower respiratory tract (thoracic cavity)
What are the componentes of the upper respiratory tract?
head & neck
nasal cavity
where does the upper respiratory tract starts
nostrils aka nares (naris)
the nasal is separated by
nasal septum
Why do we breathe through the nose?
filters, warms and moisturizes the air
keeps the sinus clear
nasal conchae (turbinate bone) is part of what bone and name the 3 parts of the bone
nasal conchae is part of the ethmoid bone
superior
middle
inferior
what does the air passage way of the nasal forms
forms the 3 nasal meatuses (tube)
What is the paranasal sinuses
it is the spaces inside the bones
sinuses are connected by tubes to the nasal cavity
the spaces also help cools the brain
What are the 4 main bones that have sinuses?
frontal
sphenoid
maxillary
ethmoid
This bone is one of the 4 main bone that have sinuses and is where you find the pituatary gland. The pituatory sits behind this bone.
sphenoid
This is the largest sinues of the 4 main bones that have sinuses
maxillary
the maxillary bone is also known as the
maxillary antrum
This helps block the nasal cavity
uvula
what are the 3 sections of the Pharynx
nasopharynx
oropharynx
larynogopharynx
this section has the eustachian tube aka auditory tube also includes the pharyngeal tonsil (adenoid tonsils)
nasopharynx
this section contains 2 palatine tonsils and 2 lingual tonsils
oropharynx
this section includes the epiglottis
laryngopharynx
what type of tissue is the epiglottis made of
connective tissue made of cartliage
what does the epiglottis flap covers?
the glottis
what is the opening to the larynx
glottis
what closes the glottis when swallowing and involved in choking?
the epiglottis
This is known as the voice box
larynx
The thyroid cartilage is known as the
Adam's Apple
What is the cartilage under the thyroid cartilage
cricoid cartliage
What type of cartilage is in the larynx
arytenoid cartilage in the larynx
what structure is after the cricoid cartilage?
vocal cords
This is the inner vocal cord and is made of cartilage. This is known as the
true vocal cord
this is the outer vocal cord and is made of vocal folds. This is known as the
false vocal cord
This separates the upper and lower respiratory tract and has rings of cartilage that are c shaped?
Trachea
y shaped cartilage at the bottom of the trachea
carina
the 3 branches of the bronchi is called the
bronchial tree
what are the 3 branches of bronchi or known as the bronchial tree
primary bronchi (2)
secondary bronchi (5) 3 on right/ 2 on left
tertiary bronchi (10)
The tertiary bronchi is connected to these smaller tubes cartilage that gets smaller
bronchioles
the terminal bronchials leads to
air sacs
are there any gas exchange in the terminal bronchioles?
no
where does the gas exchange begin?
in the respiratory bronchioles which have alveoli on the surfaces. Its in the alveoli is where the gas exchange occurs
what are cluster of alveoli
air sacs
where does the gas enters from
Oxygen enters the blood from air in the aveolus
O2 enter blood from air in the the aveolus then what gas leaves the blood stream and enters air
CO2
what type of tissue is the aveoli
simple squamos epithelium. it is one cell thick. very thin
this is the wall of the aveolus and walls of the capillary
respiratory membrane
