Microscopic air sacs located in the peripheral parts of the lungs that consist of simple squamous epithelial tissue. Alveoli and pulmonary capillaries create the respiratory membrane where gas exchange occurs between atmospheric air and blood.
A term used to describe when carbon dioxide is bound to hemoglobin; something to note is that oxygen and carbon dioxide do not compete with each other when binding to hemoglobin.
A quaternary pigment protein found on red blood cells, hemoglobin is primarily used to transport oxygen and some carbon dioxide throughout the blood.
The term used to describe when oxygen is bound to hemoglobin; oxygen + hemoglobin = oxyhemoglobin.
Differences in pressures created by different concentrations of air in different areas.
A term used to describe the movement of gasses across a semi-permeable membrane; in this case it would be the gas exchange process that occurs at the respiratory membrane (alveoli and pulmonary capillaries).
The respiratory membrane consists of alveolar air sacs and pulmonary capillaries, and is where the actual site of gas exchange occurs between atmospheric air and the blood.
