The cardiovascular system, along with the circulatory system, provides nutrients and oxygen through blood to organs and other parts of the body. It is vital to maintain a healthy lifestyle in order to prevent disease and dysfunction of the cardiovascular system.
The cardiovascular system consists of the heart, blood vessels, veins and arteries. This system is often associated with the circulatory system (they are sometimes considered the same system) and it is very important to the overall function of the body.
The cardiovascular system continually delivers blood to different parts of the body. The heart acts as the main pump, and blood vessels transport nutrient-filled blood to the organs.
Veins and Arteries
Veins carry blood and oxygen to the heart, and arteries carry blood and nutrients away from the heart.
The heart is divided into four chambers: a right and left atrium and a right and left ventricle. These parts are often referred to as the right heart and the left heart.
Blood is the primary fluid for nutrient and oxygen transport in the body. It is made up of red blood cells, white blood cells, plasma and platelets. If the count for any of these substances is lacking, medical issues may arise.
