respiratory system

Respiratory system

• meant to regulate the pH of your blood

• based off of CO2

Pulmonary Ventilator

• moving air in and out of the lungs

Types of Respiration

• External Respiration

  • diffusion of gases between lungs and blood

    • oxygen and carbon dioxide

    • diffusion of both gases occur at the same time

• Internal Respiration

  • diffusion of gases between blood and tissues

• Cellular Respiration

  • sugar (C6H12O6) + 6O2 →6CO2 + 6H2O + ATP

CO2 + H2O →H2CO3 (carbonic acid)

• if you can’t make enough carbonic acid your pH goes up

Vibrissae (nose hairs)

• filters coarse materials

Conchae (parts in the nosal cavity)

• mixes incoming air

Pharyngotympanic Tube

Uvula

• flattens so food and liquid don’t go upto into your nose when you swallow
