The cardiovascular system is the set that includes the heart and blood vessels and is responsible for the supply of oxygen-rich, low-carbon blood to all organs in the body, allowing them to function properly.
In addition, another important function of this system is to bring blood from all over the body, which is low in oxygen and must pass through the lungs again to perform gas exchanges.
The main components of the cardiovascular system are
The heart is the main organ of the cardiovascular system and is characterized by a hollow muscle, located in the center of the chest, that functions as a pump. It is divided into four bedrooms:
The right side of the heart receives blood rich in carbon dioxide, also called venous blood, and takes it to the lungs, where it receives oxygen. From the lungs, blood flows into the left aorta and from there to the left ventricle, from which the aorta comes, which carries oxygen-rich blood and nutrients throughout the body.
To circulate throughout the body, blood flows into the blood vessels, which can be classified as:
All the functioning of the cardiovascular system is based on heart rate, where the atria and ventricles of the heart relax and contract, forming a cycle that will guarantee the entire circulation of the body.
The cardiovascular system can be divided into two main parts: pulmonary circulation (small circulation), which carries blood from the heart to the lungs and lungs to the heart and the systemic circulation (large circulation), which carries blood from the heart to the heart. tissue through the artery of the aorta.
The physiology of the cardiovascular system also consists of several steps, including:
Finally, oxygen-rich blood irrigates the entire body, providing the energy needed for the functioning of all organs.
There are several diseases that can affect the cardiovascular system. The most common are:
Cardiovascular disease, particularly coronary heart disease and stroke, is the leading causes of death worldwide. Advances in medicine have helped reduce these numbers, but the best treatment is prevention. Find out what needs to be done to prevent a stroke in 7 tips to reduce the risk of heart attack and stroke.
