Explaining Alveoli and Blood Gases in Spanish

Welcome to our third free audio lesson introducing the COPD Module of our Puolmonary Medicine Course.

In the last premium audio lesson, the doctor explained the progressive nature of COPD and the need for regular pulmonary function testing. In this lesson, you will hear the doctor explain alveoli and blood gases.  After the dialogue, we'll review the description of alveoli and name the main blood gases in Spanish. 

Finally, if you want to master everything the doctor said in Spanish, we cover it all in the next premium audio lesson for Medical Spanish members.

Alveoli and Blood Gases

P: ¿Qué son los alveolos? Se me olvidó.

D: Buena pregunta. En este dibujo, se ven los alveolos aquí. Los alveolos son las bolsitas de aire al final de las vías respiratorias donde la sangre recibe oxígeno y se deshace del dióxido de carbono. También vamos a sacarle sangre de una arteria en la muñeca para medir los niveles de estos gases en su sangre.

P: Ay sí. Recuerdo esta prueba. Duele.

D: Sí duele más que sacar sangre por la vena, pero nos da información esencial y lo haremos solamente cuando sea necesario.

P: Menos mal.



Let’s sum things up with a brief audio quiz!
