How It Works
Artherosclerosis - hardening and narrowing of the arteries. Silently and slowly blocks arteries, putting blood flow at risk. Causes are high blood pressure and high cholesterol.
Coronary artery disease - narrowing or blockage of the coronary arteries, the blood vessels that supply blood to the heart itself.
Compare and Contrast: Respiratory System and Cardiovascular System
The difference between the circulatory and respiratory systems is the circulatory system carries blood throughout the body and the respiratory system is the way the body exchanges gases between the blood and air. The two systems work together in that when the heart beats, oxygen deprived blood exits the heart via the pulmonary artery. Blood travels down the pulmonary artery to the lungs (the word pulmonary refers to the lungs in human anatomy) where it enters a capillary system surrounding the aveloi in the lungs. It is here where excess carbon dioxide exits the blood and oxygen enters. The oxygen rich blood now returns to the heart where it is pumped out via the aorta to the rest of the body.
