The role of the lungs in pulmonary circulation
By: Cyndi Li
The human body is a wonderfully constructed intricate network of systems that, working in unison, are able to sustain life. The role the lungs play in the human circulatory system are so vital, the system would fail to function properly without them. Here's why. The...
An overview of pulmonary circulation
By: Alysa Dudley
Every day we breathe in and out, and most of the time we don't even think about it. We breathe air in through our nose, it goes through our windpipe (the trachea), and then into our lungs. What happens after the air gets into the...
The role of the lungs in pulmonary circulation
By: Leslie Schwab
The role of the lungs in pulmonary circulation is as important as that of the heart. The lungs are a pair of organs that occupy the human chest cavity, and are positioned on either side of the heart. The lungs play two critical roles...
The heart's role in circulation
By: Cyndi Li
Part of the human circulatory system is an amazing network of natural tubes called veins and arteries. This network of tubing is responsible for delivering vital blood throughout the human body. Not only is the body nourished by essential nutrients and oxygen found within the...

The human heart is only about the size of your fist. Amazingly, as small as that may seem, the heart plays a huge and vital role to the survival of life. The human heart is part of a network of organs that keep the body...
An overview of pulmonary circulation
By: Cyndi Li
The human circulatory system is comprised of two major systems, and two minor ones. The minor ones, the cardiovascular system and the lymphatic system, work in conjunction with the primary systems, the pulmonary circulatory system and the systemic circulatory system. The latter two systems play...

Most people know that the tissues and cells of our body need oxygen. So it would not be a surprise question to ask, "Why is oxygen so important to the blood." The real question is, "Why is blood so important to oxygen?"...
A look at how CPR restarts the circulatory system
By: Roan Kishpaugh
CPR, or cardiopulmonary resuscitation, restarts the circulatory system in an indirect manner. It does this by supporting the heart with oxygen until an electrical shock from a defibrillator is administered to the heart. When a person's heart stops, this is called cardiac arrest. The heart...
An overview of pulmonary circulation
By: Lisa Stephens
Pulmonary circulation is one part of the cardiovascular system that serves the lungs exclusively. Its role is to transport oxygen depleted blood away from the heart to the lungs, and return back to the heart with oxygen rich blood. Physicians and scientists have been examining...
How smoking impacts the human circulatory system
By: Cyndi Li
Cigarette smoking can lead to a host of medical conditions and diseases, lung cancer being the leading one. As much as the lungs are adversely affected by smoke it's not just these two vital organs that are affected. Considering the human body works as a...
