Respiratory System

Cards (51)

  • All cells require a continuous supply of oxygen and must continuously get rid of metabolic waste product, carbon dioxide.
  • Generally, the term respiration simply means ventilation or breathing.
  • It is responsible for the exchange of gases between the body and the air, a process called respiration.
  • External Respiration is the process by which gases are exchanged between the blood and the air.
  • Internal Respiration is the process by which gases are exchanged between the blood and the cells of the body
  • Cellular respiration is the process by which cells use oxygen for metabolism and give off carbon dioxide as a waste product.
