- Respiratory System Overview
- Network of organs and tissues that help you breathe
- Consists of airway, lungs, and blood vessels
- Roles
- Gas Exchange
- Occurs at interface of lungs (alveoli) and capillaries
- Blood is oxygenated and sent out to body
- CO2 waste from body is exhaled
- Trapping particulate matter
- Airway structure traps potentially harmful particulate matter and ushers it out
- Epithelial cells produce mucus secretions and other antimicrobial secretions to inhibit infection
- Thermoregulation
- Breathing rate regulates body temperature by modulating expiration of hot air
- Respiratory rate increases in response to increased temperature (panting)
- pH Regulation
- Respiratory rate regulates pH of blood by adjusting pCO2 of blood
- Shifts carbonic anhydrase equation
- Respiratory rate regulates pH of blood by adjusting pCO2 of blood
- Gas Exchange
