HST-AP Introduction to the Respiratory System

The Respiratory System plays a major part in our survival and works hand in hand with the Circulatory System.
Respiration for the body can not happen without the circulation of the blood driven by the cardiovascular system. Simply said, it is through the respiratory structures that Oxygen (a gas) is directed to the lungs and passed into the blood transportation system which then delivers the Oxygen to the body. But this is just half the trip.
In this short video about the Respiratory System, we will discuss how a breath of fresh air is taken in through the respiratory pathway by the following structures...the nose, pharynx, larynx, trachea, bronchi tubes, and the lungs including the alveoli. All of this will be explained in this easy to understand detailed animation of the Respiratory System.
