1. Chapter Eleven
Respiratory System

2. Learning Outcomes Describe the purpose of the lungs/respiratory system
Basic functions and anatomy of respiratory system
Medical terms for system
Measurement tools

3. Functions of the Respiratory System
Supplies oxygen (ox/o) to cells
Removes carbon dioxide (capn/o)
Filtering, cleansing, warming, humidifying air
Regulation of blood pH
Role in sound, speech, and smell

4. Functions of the Respiratory System
Respiration (spir/o)
Inspiration/ inhalation
Expiration/ exhalation
The respiratory system: nasal cavity, pharynx, larynx, trachea, bronchus, and lung with expanded views of the trachea and alveolar structure.

19. Anatomy and Physiology: Lower Respiratory Tract
Trachea (trache/o)
Mediastinum (mediastin/o)
Bronchi (bronch/o, bronchi/o)
Bronchioles (bronchiol/o)
Alveoli (alveol/o)
Lungs
Lobes (lob/o)
Pleura (pleur/o)
Diaphragm (phren/o, diaphragm/o, diaphragmat/o)
Intercostal (cost/o) muscles

20. Disorders of the Lower Respiratory Tract
Chronic obstructive pulmonary disease (COPD)
Emphysema
Asthma
Bronchitis
Asthma Factors

21. Normal Inflammation
# 1 Inflammation: when the muscles in the bronchioles start to swell up
# 2 excess mucus: When the adrenal glands start to produce more mucus than needed, this add to the narrowing of the space to breath in and out

22. Bronchoconstriction Bronchiole Tightened Muscle
Alveoli with trapped air
#3 Bronchoconstriction: when the muscles surrounding the bronchioles tighten out like rubber bands
The tightening of the muscles is what will not let the old air out of the air sacs, if we can not get the old air out then we can not let new air in, this is where asthma really occurs
