How Does the Cardiovascular System Work With the Respiratory System

In order to understand how these systems work together, we must look at them each on their own.

Cardiovascular System

The cardiovascular system in the human body consists of the heart and blood vessels, which can be further divided into arteries, veins and capillaries.

The heart pumps the blood to all parts of the body, by means of the blood vessels. The heart is divided into four chambers, two for oxygen rich blood, and two for blood with very little oxygen. The oxygen rich blood is transferred throughout the entire body to supply the muscles and other tissue with the oxygen it needs to function.

Oxygen rich blood within the arteries is under very high pressure, and thus needs to travel to the capillaries (small, low pressure blood vessels) which deliver the blood to the different bodily tissue, and then absorbs the carbon dioxide and transports it back to the heart.

Respiratory System

The respiratory system is made up mostely of the airways, the lungs and certain muscles that help move air to and from the lungs. The airway starts at the nose and mouth, then continues down through the throat into the bronchi. These are small airways that eventually feed into the lungs, and are lined with cells called alveoli.

The other part of the respiratory system is the muscles. These include the intercostals (muscles between the ribs) and the diaphragm, which cause the lungs to expand and contract.


The two systems have the same goal, which is moving oxygen into the body and moving carbon dioxide out. The two systems work together, as the respiratory system gets the oxygen from outside the body, then the cardiovascular system transports it within the body, and finally the respiratory system is in charge of letting the carbon dioxide out of the body once again.

Positive Blood Flow

For a healthy respiratory system, good blood flow is crucial. We recommend exercise to increase blood flow, which will increase oxygen supply in the body and to the brain. You can also take the Manna Blood Circulation Support supplement to help increase blood flow for the same reason.
