How does the cardiovascular system interacts with other bodily systems? The heart is the major organ of the cardiovascular system. All through history, experts have referred to it as seat of the soul. According to history books, the ancient Egyptians weighed the heart after a person's death because they believed that the weight of the heart equaled the weight of the soul. This is the starting point and the end point of life.
The Cardiovascular system is connected with all the other bodily systems because of our body organs need of red blood cells (RBC). Without RBC's, body organs will die. Starting from the vena cava, a major vein in our body, un-oxygenated blood enter the four chambers of the heart. These chambers are called right and left atrium and right and left ventricles. There are valves in between these chambers to keep the blood flowing in one direction. From the right ventricle, the un-oxygenated blood enter the lungs and picks up oxygen and come backs in to the left atrium. Oxygenated blood then goes into the left ventricle where it gets pumped out to reach all the organs of the body to receive oxygen and this is made possible by the blood vessels. Oxygenated blood is delivered by arteries to other bodily system and un-oxygenated blood is received by the vein and goes to the heart to get oxygenated again.
It's like a the system of the highways and roads that enables us to travel from place to place in a circle. Started from the heart, and it circulated in the heart and lungs, and out the heart, and back on the road to the organs. And that is how the Cardiovascular system interacts with other bodily systems.
