Introduction to Respiration
- Respiration: Define
- Ventilation: Define
- Respiratory tract is divided in two ways
- Functionally
- Conducting
- Pressure changes as air is inhaled/exhaled
- Prevent collapse with bone and cartiliage
- Respiratory Mucosa: Columnar Cells with cilia on luminal surface, goblet cells interspaced
- Beat mucus upwards to phyarnx.
- Respiratory
- Clinically
- URT
- Nose, Mouth, Pharynx and Larynx
- Nose (Cleans, Warms and Humidifies)
- Pharynx
- Food/Drink = Osephagus
- Air = Larynx
- Larynx
- Tube with reinforced cartiliage, can move relative of one another.
- Contains the vocal chords
- - Protect lower airway from food ingestions
- Voice production
- LRT
- Lungs = Air filled sacs made of tiny aveolaur sacs
- Right = 3 Lobes
- Left = 2 Lobes
- Lung Structure
- Alveolar sacs
- Thin walls = rapid gas exchange
- Pneumocytes and capillaries
- Pleura = Parietal/Visceral
- Trachea
- Bronchi
- Main Bronchi
- Lobar bronchi
- Segmental bronchi
- Bronchioles
- Cells of the LRT
- Respiratory epithelia
- Brush cells
- Basal cells
- Small granule cells
- Clara cells
- Gas exchange epithelia
- Type 1
- Type 2
- Gel on Brush Model
- Mechanisms of Ventilation
- Thoracic Wall
- Intercostal Mucsles
- Internal/External
- Ribs and Sternum
- Diaphragm
- Accessory Muscles
- Pectoral
- Scalenes
- Abdominal
- Cystic Fibrous
- Diagram of the Lungs
