Coronary heart disease, or Atherosclerosis, is a disease in which plaque, a waxy substance, is built up in the coronary arteries. Plaque can harden or break open after a while. Hardened plaque partially blocks the arteries and reduces the flow of oxygen-rich blood to the heart. Ruptured plaque can lead to blood clots which can completely block…

from one healthy human being to a patient; whom might be losing too much blood or suffering from an illness that requires more blood. This medical procedure is crucial in saving numerous lives. The first successful human-to-human blood transfusion was performed by James Blundell in 1818, yet a large number of patients had died because of wrong blood transfusion operations. The great discovery of Karl Landsteiner’s classification of ABO blood types in the 20th century had enabled human to…

They can also damage the function of your heart and the structure and function of your blood vessels. The damage done by these chemicals make a smoker susceptible for atherosclerosis. This is a condition in which a plaque like material builds up in the arteries. This build up makes it difficult for blood to flow smoothly throughout the body. Coronary heart disease occurs when plaque builds up in the arteries of the heart. CHD can lead to heart failure, heart attack, or even death. A smoker is…
