KEY TERMS

RESPIRATORY TRACT

Respiration- exchange of gases between animals and it’s environment

Opening of the body where one breathes

Nose (Nostrils) covered by epithelial tissueEpithelial Tissue protected by mucus

UPPER AIRWAYS

Epithelium filters airParticles trapped by mucusLined with CiliaMoves the mucus towards the pharynxThis protects the lower airways

IRRITATION IN NOSE AND MOUTH

Pharynx common area shared by the nose and mouth

NoseReaction: Sneezing

MouthReaction: Coughing

LARYNX, TRACHEA, AND LUNGS

Used to assist breathing Larynx leads to the trachea Trachea splits into two Bronchi

Lungs Produce a surfactant Coats the alveoli

Covered in Pleura

MECHANISMS OF BREATHING

Inspiration- air is taken into the lungs

Expiration- air is forced outBrain controls the normal rate of respiration

Respiration rate changes in response to bodies demands

Breathing is involuntary

RESPIRATION RATES IN ANIMALS

Cat= 26bpm Dog= 22bpm

Sheep= 19bpm Cow= 30bpm

Horse= 12bpm Human= 12bpm

Guinea Pig= 90bpm Hamster= 74bpm

CLINICAL PRACTICES

1) Oxygen levels to low causes blood to have a dark bluish appearance

This is called cyanosisCyanosis- definite indication that tissues are not getting enough oxygen

CLINICAL PRACTICES CON’T

Pneumonia- disease; inflammation in the lungs, caused by an infection in the lungs

White blood cells assist in getting rid of the bacterial infection

Pneumonia causes…. Pleural Friction RubPleural Friction Rub- creaking saddle noise while breathing shows that the lungs and chest are inflamed and irritated

OTHER KEY DISEASES AND PROBLEMS Heaves- horse disease causes

coughing/thick nasal discharges Roaring- horse disease where

vocal folds fail to openThis causes a roaring noise

PRACTICES AND TOOLS

Stethoscope- evaluates breathing in animals

Medications Surgery Bronchodilators- medication that

opens airways
