Question
Chapter 34.4, Problem 2CYL
Summary Introduction
To answer:
How oxygen and carbon dioxide are transported and exchanged between the lungs and body cells.
Introduction:
The primary function of the respiratory system is a gas exchange. Inhaled oxygen enters the lungs and reaches the alveoli sac. The layer of cells lining the alveoli and the surrounding capillaries is a single layer thick and are in very close proximity to each other. Transportation of oxygen and carbon dioxide occur through blood
