Histology: Respiratory System

Histology: Respiratory System — Expert Guide

How it begins

El sistema respiratorio tiene como función primordial el intercambio gaseoso entre el organismo y el medio externo: aportación de O₂ a la circulación y eliminación de CO₂. Para ello se organiza en un sistema de conductos de calibre decreciente que acondicionan el aire inspirado (humidificación, calentamiento y depuración de partículas) y lo conducen hasta la superficie de intercambio gaseoso, cuya área total en el…
