where does the upper respiratory tract starts
nostrils aka nares (naris)
the nasal is separated by
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
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?
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.
This is the largest sinues of the 4 main bones that have sinuses
the maxillary bone is also known as the
This helps block the nasal cavity
what are the 3 sections of the Pharynx
this section has the eustachian tube aka auditory tube also includes the pharyngeal tonsil (adenoid tonsils)
this section contains 2 palatine tonsils and 2 lingual tonsils
this section includes the epiglottis
what type of tissue is the epiglottis made of

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

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
the terminal bronchials leads to
are there any gas exchange in the terminal bronchioles?
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
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
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
