The ventricles are the lower heart chambers that contract to pump blood. The upper chambers, atria, also contract, but to a lesser degree.
contracture
The heart moves the blood all over the body the heart it self is no exception. The heart is a cardiac muscle.
This is not a question please rephrase.
The heart muscle is supplied by blood vessels called coronaries.
The circulatory system = the heart + the blood vessels. The heart is a muscle, but the muscle fibers are slightly different to skeletal muscle. Arteries has a thin layer of muscle cells that surround them so that they can constrict or expand the blood vessels in order to regulate blood pressure.
No. A form of involuntary muscle known as cardiac muscle pumps the blood through the heart.
The path followed by the blood when it supplies and drains the heart muscle
heart
Because your heart is a muscle, a cardiac muscle. a muscles job is to contract an that is exactly what the heart does, it contracts to pump blood.
The heart is protected by the cardiac muscle which is an involuntary muscle that allows the heart to pump blood.
The name of the blood vessel which supplies glucose and oxygen to the heart muscle is an artery. Arteries carry blood away from the heart.
The heart is made up of muscle tissue (cardiac muscle). The muscle tissue contracts to pump blood.
