What is miocardia?
Miocardia is the decreasing heart volume during systolic contraction. The rhythmic contraction of the heart, especially the ventricles, via which the blood is returned/ pushed through the aorta and pulmonary artery after each diostole.
How can blocking an artery in the heart cause heart damge?
An artery is a pathway for the blood to travel to and from the heart. If the artery is block, the heart cannot release or receive blood, and therefore, causes heart problems.
Why the pulmonary veins carrying the oxygenated blood and not the pulmonary artery?
it's a pulmonary VEIN because the blood isn't under as much pressure (because it has yet to get to the heart) where as the pulmonary artery is coming straight from the heart so is under more pressure. (the pressure is caused by the heart's contractions)
Where does the carotid artery carry blood from?
The carotid artery carries blood from the heart to the neck and head.
What is an artery that supplies blood to the heart?
The coronary arteries supply blood to the myocardium (heart muscle).
What is the difference between a heart beat and a pulse?
A heartbeat is the contraction and relaxation of the heart muscle, while a pulse is the rhythmic expansion and contraction of an artery as blood is pumped through it by the heart.
Why is the direction of the wave of contraction in the heart so important?
The direction of the wave of contraction in the heart is important because it decides where the blood reflux will take place. The blood reflux could take place in the atria, or the blood from the heart could be ejected into the pulmonary artery or aorta.
The alternating expansion and contraction of artery walls caused by the contraction and relaxation of the ventricles?
This process is known as the pulse and is the result of the heart pumping blood into the arteries. As the heart contracts (systole), blood is pushed into the arteries causing them to expand. When the heart relaxes (diastole), the arteries recoil back to their original shape, creating a pulse that can be felt in different parts of the body.
Why is the blood in an artery flow faster and at a higher pressure than blood in a vein?
It is because your arteries An artery carries blood away from the heart, to the cells of the body. But your veins the vein carries the blood back to the heart

The cells of the heart are supplied with blood via the?
The cells of the heart are supplied with blood through the hearts own artery. The artery that supplies the heart blood is known as the coronary artery.
What type of blood vessels carries blood away from the heart?
Artery
Which artery give oxgyenated blood to heart?
The Coronary Artery supplies the heart with oxygen rish blood.
How can blocking an artery in the heart cause heart damge?
An artery is a pathway for the blood to travel to and from the heart. If the artery is block, the heart cannot release or receive blood, and therefore, causes heart problems.
What is a cardiac artery?
It is an artery sending blood from the heart.
Major artery that supplies the heart to the lungs?
The artery that sends blood from the heart to the lungs is called the pulmonary artery. The pulmonary vein delivers blood back to the heart.
