Question

The source of blood carried to capillaries in the myocardium would be the ________. A. coronary veins B. fossa ovalis C. coronary arteries D. coronary sinus

Answer 1

Answer:

C. coronary arteries

Explanation:

The source of blood carried to capillaries in the myocardium would be the coronary arteries.

Answer 2

The source of blood carried to capillaries in the myocardium would be the coronary arteries.

The myocardial irrigation is carried out through the right and left coronary arteries, these blood vessels supply oxygenated blood to the myocardium.

Both arteries originate at the level of the sinuses of Valsalva at the root of the ascending aorta close to the aortic valve.

• The left coronary artery divides into two arteries, the anterior descending artery and the circumflex artery, supplying blood to the left side of the heart.

• The right coronary artery supplies blood mainly to the right side of the heart.

Normally, coronary flow is self-regulated by local metabolic mechanisms, according to variations in myocardial O2 consumption.

If the arteries of the heart deteriorate and become clogged, a myocardial infarction occurs.

In the absence of irrigation due to a complete blockage of the blood vessel, the cardiac cells perish and a myocardial infarction occurs, which is fatal if it is not treated urgently.

Therefore, we can conclude that the source of blood carried to capillaries in the myocardium would be the coronary arteries.
