Tutorial

En esta lección vamos a repasar el proceso de la respiración y cómo su cuerpo intercambia gas y lo transporta a través del cuerpo.

TERMS TO KNOW
  • Respiration

    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).

  • Alveoli

    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.

  • Hemoglobin

    A quaternary pigment protein found on red blood cells, hemoglobin is primarily used to transport oxygen and some carbon dioxide throughout the blood.

  • Pressure gradient

    Differences in pressures created by different concentrations of air in different areas.

  • Respiratory Membrane

    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.

  • Oxyhemoglobin

    The term used to describe when oxygen is bound to hemoglobin; oxygen + hemoglobin = oxyhemoglobin.

  • Carbaminohemoglobin

    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.
