A heart attack occurs when the flow of blood to the heart is blocked, most often by a build-up of fat, cholesterol and other substances, which form a plaque in the arteries that feed the heart (coronary arteries). The interrupted blood flow can damage or destroy part of the heart muscle. A heart attack, also called a myocardial infarction, can be fatal, but treatment has improved dramatically over the years. It's crucial to call 911 or emergency medical help if you think you might be having a heart attack.
Irises are classified as being one of six colors: amber, blue, brown, gray, green, hazel, or red. Often confused with hazel eyes, amber eyes tend to be a solid golden or copper color without flecks of blue or green typical of hazel eyes. Blue eyes have a low level of pigment present in the iris.
As the child develops, the cells begin to produce melanin which eventually determines the final color of the eyes as well as the skin and hair. Eye colors range from brown, which is the most common, to green, the most rare, with shades of blue, amber, hazel and gray somewhere in between. Eye color is generally determined by the amount of pigment in the eye and this is decided by our genetic makeup long before we are born!!
