Respiratory System

Body Systems


The respiration system has organs that are used for the process of respiration in an organism. Involves the intake and exchange of oxygen and carbon dioxide between organism and environment.


Alveoli may be small but there are many that make a large space to exchange air. Walls are made of a single layer of cells as are the capillaries which have low oxygen and high carbon dioxide. Allows oxygen to go into blood and carbon dioxide to get out of the blood. Some cells in the walls secrete fluid allowing gases to dissolve. Fluid also prevents the sides of alveoli from sticking together.

Carbon Dioxide and Oxygen Transported to Blood

Oxygen goes into the lungs and carbon dioxide is take out of the blood. Oxygen carries the cells and carbon dioxide is carried away.
