Respiratory System Jordyn Miller Period:2 - Coggle Diagram
Respiratory System Jordyn Miller Period:2
Upper Respiratory
Nose
contains coarse hairs, prevent entry of particles
Nasal Cavity
Hollow space behind nose, divided by nasal septum
Sinuses
air filled spaces inc, maxillary, frontal, ethmoid, & Sphenoid
Pharynx(Throat)
Space behind oral
Internal Respiration
Gas exchange between lungs and blood
Lower Respiratory
Larynx (vocal Cords)
Trachea
leads & Splits into Right & Left bronchi
Bronchial Tree
consists of branched mucous membrane leading from trachea to lungs
Lungs
Take up majority of the thoracic cavity & is enclosed by the diaphragm
Alveolar Sac
Alveoli
External Respiration
Gas exchange between blood and body cells
Volumes and pressure
Total Lung Capacity (0-6,000 mL)
Expiratory Reserve (0- 1,000mL)
air that can be exhaled during maximal expiration
Residual Volume (0-1,200mL)
air that remains in the lungs after maximal expiration, doesn't leave the lungs
Functional Residual Capacity (0-2,500 mL)
Tidal Volume ( 2,500-3,000mL)
air that enters lungs or leaves the lungs during respiratory cycle
Vital capacity (1,000-6,000mL)
Inspiratory Reserve (3,000- 6,000mL)
air that can be inhaled in addition to Tidal volume, during forced inspiration
Inspiration Capacity (0-6,000mL)
Atmospheric pressure 760 mmhg
Respiratory Disorders
COPD
Chronic Obstructive Pulmonary Disorder; Chronic bronchitis or emphysema
Tuberculosis
Bacterial infection in the respiratory system caused by myocardium
Pneumonia
Bacterial or viral infection of the lungs
Lung Cancer
Uncontrolled cell growth & development of tumors in the lungs
Seasonal Flu
A viral infection with many variations of the virus changes rapidly year to year
Pleurae Layers
Parietal Pleura
Outer lining of lungs
Visceral Pleura
Inner lining of lungs
Respiratory Capacities
Inspiratory Capacity
air inhaled after normal inspiration (IRV + TV)
Functional Residual
air that remains in lungs after resting expiration (ERV+RV
Vital capacity
maximal amount of air that can be exhaled (TV+ IRV + ERV)
Total Lung Capacity
Total volume of air the lungs can hold (VC+ RV)
