The heart itself is a muscle. These contractions generate the force, which is the force of contraction, which results in a decrease in the venticular volume in case of the ventricles or decrease in the atrial volume in case of the atria, this is followed by an increase in the venticular or atrial pressure respectively. which allow ejection of oxygenated and deoxygenated blood to flow into and out of it to circulate throughout the body. thus giving you air to breathe and blood to pump to stay alive.
Yes, the heart is an involuntary muscle. It contracts without conscious control.
it contracts rhythmically
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
The heart is made up of muscle tissue (cardiac muscle). The muscle tissue contracts to pump blood.
Yes, the heart is an involuntary muscle. It contracts without conscious control.
The muscle tissue on one side contracts while the other relaxes, controlled by electrical impulses to the heart muscle.
Cardiac muscle is found in the heart. It contracts, causing the heart to beat and blood to circulate through out the body.
systole
the heart is a muscle that expands and contracts or pumps blood throughout the body.
An example of cardiac muscle is the myocardium, which is the muscle tissue of the heart. It is responsible for the contraction of the heart chambers to pump blood throughout the body. Cardiac muscle is striated and involuntary, meaning it contracts without conscious control.
