What is angina

The heart is an important muscle in the human body. It is characterized by its conical shape. It pumps oxygen and food to all parts of the body, as well as returning carbon dioxide blood to the lungs to purify it. Through coronary arteries, the heart gets its food from oxygenated blood, But in some cases there is a lack of blood that passes through the coronary arteries feeding the heart, which causes imbalance between the consumption of the heart for food and food, which causes the incidence of angina or angina.
