Question

The arteries which supply blood to the heart is
(a)Pulmonary arteries
(b)Hepatic arteries
(c)Coronary arteries
(d)Carotid arteries

Answer 1

Hint: The arteries are for coronary circulation, which means they transport blood that is rich in oxygen to the heart muscle. Like all the other organs, the heart requires a non-stop supply of oxygen to work properly, and these arteries surround the heart to supply oxygen.

Complete answer:
The arteries which supply blood to the heart are called the coronary arteries. The right side of the heart gets oxygenated blood from the right coronary artery and the left side of the heart receives blood from the left coronary artery supplying blood to the left side of the heart.
The blood supply to parts like the stomach and intestine are provided by the Hepatic artery and blood supply to parts like the face and neck are provided by carotid arteries.

Additional Information: -In the diastolic phase and the systolic phase, the diastolic phase shows the period where the ventricles are relaxed. In this time flow of blood is from the left and right atrium to the left and right ventricle.
-The blood travels via atrioventricular valves which separates the atria from the ventricles. The right atrium gets carbon dioxide-rich blood from the body by superior and inferior vena cava.
-The left atrium gets oxygen-rich blood from the lungs by the pulmonary veins. The diastolic phase ends by both the atria contracting and adds extra blood into the ventricles.
So, the correct answer is coronary arteries.

Note: -Atherosclerosis disease related to arteries where plaque accumulates on the wall of the arteries along with cholesterol which narrows down the blood flow causing disorder to the heart and can be lethal if not treated.
-Systolic phase is the time of contraction of the ventricles that takes place and push the blood into the aorta and pulmonary artery.
-Sound of heartbeat is represented by Lubb and Dub sound. Lubb sound is formed by the closing of atrioventricular valves and the closing of semilunar valves at the root of the pulmonary artery and aorta produces Dub sound.
