Under the larynx
Diaphragm

Larynx
Top of neck
Pharynx
Behind mouth and Nasal cavity
Lung capacity terminology

Tidal volume- Air moved by one respiration
Respiratory capacity-combination of two or more volumes
Total capacity- sum of all volumes
Internal and External respiration
Respiration
Inspiration- air moving into lungs
Expiration- air moving out of lungs
External respiration- allows exchange of gasses between blood and alveoli by diffusion
Internal respiration- oxygen moves out of blood and into tissue cells
Disorders of the respiratory system
COPD- a progressive disease that makes it hard to breathe (bronchitis & emphysema)
Symptoms- cough, dyspnea, wheezing Treatment opt. - Spirometry
Tuberculosis- Bacterial infection by Mycobacterium tuberculosis
Symptoms- cough w/ blood, fatigue/ chills, weight loss Treatment opt. - long term antibiotics, surgery
