Nasal meatus
is a nasal passage of the nasal cavity, of which there are 3, superior,middle and inferior.
Turbinates
are thin, scroll-like bones with nasal epithelium that occupy most of the lumen of the nasal passages
Nasal meatus
divide each nasal passage into three main passageway

glottis
opening into the larynx
Epiglottis
cover the glottis when the animals swallows
Aryenoid cartilage
vocal cords
Trachea
Anterior to Bronchi then splits in to bronchi; for conduction of air; hyaline cartilege (15-20 incomplete rings); has ciliated epithelium

What are intercalated disc?
Cells of cardiac muscles fit together to form
these structural medications that allow the cardiac muscle to act as a unit.
What is the difference between the artery veso, capillary.

2. middle layer is tunica media
3. inner layer is tunica intima
Which valve is the most common in chronic Valvlar disease?
Mitral valve
Canine Dilated Cardiomyopathy
What would be consequence of thin, atrophied,weak ventricular walls?
increased diameter of cardiac muscle.
What does Hypertrophic means?
Thick inwards
abnormally increased muscle mass due to a hypertrophied non dilated left ventricle making it harder to pump blood
