Lower Respiratory System Trachea

• Air passage Bronchi

• Branches of lung Alveoli

• Most gas exchange Thorax

• Location of lungs Pluera

• Membrane containing lungs

Diaphragm • Aides in breathing,

separates the peritoneal and thoracic cavity

Common Procedures

Bronchoalvelor lavage•Collection of fluid via fluid flush

Percussion•Tests density by tapping on body

surfaces. Fluid filled vs. air filled differ in sound (liquid in lungs?)

Radiography (Xray) Thoracocentesis

•Puncture chest cavity to remove fluid

Common Ailments : Respiratory System

Aspiration: inhalation of a foreign object Epistaxis: nosebleed Pleural Effusion: accumulation of fluid in

the pleural space Pulmonary edema: fluid in the lung

tissue Rhinorrhea: nasal discharge Stenotic nares: narrowed nostrils that

reduce air flow

Activities Chapter 9 book review: Given later in the week Draw the path of breathing ( Figure 9-9) : Due

Monday when you leave Draw the lungs and label their parts. Be able to

define what purpose they serve in the respiratory system. Due Monday when you leave

Research one respiratory disease• Symptoms, Signs, Cause, Treatment, Prevention

• ID the breed of animal

• Put on notebook paper, you will be able to use this on your exams.
