accumulation of fluid Petechia – a pinpoint skin hemorrhage Verruca – wart Keloid – overgrowth of scar tissue

Function – exchange oxygen (O2) and carbon dioxide (CO2) between the atmosphere and body cells; this is called respiration

During breathing (external respiration), O2 passes from lungs to blood in capillaries

CO2 also passes from capillaries back into the lungs to be expelled

During internal respiration, body cells take on O2 from the blood and give back CO2, which is taken to the lungs

Inhalation brings air into the lungs Exhalation expels air from the lungs Respiration occurs every 3-5 sec.
