The pulmonary veins carries oxygen rich blood from the lungs to the heart.
By relaxing the blood vessels, antiangina drugs reduce the heart's work load and increase the amount of oxygenrich blood that reaches the heart.
coronary arteries
The heart muscle is supplied by blood vessels called coronaries.
Coronary arteries supply blood to the heart itself.
The heart muscle that has its own supply of blood from vessels is called the myocardium. It receives its blood supply primarily through the coronary arteries, which branch off from the aorta. This blood supply is crucial for delivering oxygen and nutrients to the heart muscle, enabling it to function effectively.
A heart attack or myocardial infarction is the medical term for a clot blocking one of the blood vessels that supply the heart.
Heart attacks or myocardial infarctions are caused by blockages of the coronary arteries or the blood vessels that provide the blood supply to the heart muscle itself.
The heart is made up of an intricate web of blood vessels (coronary arteries) that ensure an adequate supply of blood rich in oxygen and nutrients.
through your pulmonary artery and pulmonary vein.
coronary arteries
The organs of the circulatory system include the heart, blood, and blood vessels. The heart is the pump that takes the oxygenated blood through the blood vessels to supply the cells with energy.
Because your heart is also composed of living tissue, the blood vessels on the surface of the heart muscle supply oxygen and nutrient rich blood and take away waste and by-products like they would in any other part of your body.
