Ear drops (either oil- or water-based) are often prescribed to clear the wax or to aid subsequent ear syringing if necessary. The review of trials found that ear drops (of any sort) can help to remove ear wax, but that water and saline drops appear to be as good as more costly commercial products. The quality of the trials was generally low, however, and more research is needed.
The cardiac cycle consists of a systole and a diastole. The cardiac cycle begins with a joint diastole (relaxation of all four chambers of the heart). This is followed by an arterial systole (contraction of left and right atria) stimulated by the generation of an action potential by the Sino-Auricular Node (SA node).his is followed by closing of the AV valves which produces the sound 'lubb' and the closure of the Semilunar valves causes produces the sound 'dub'.

The Heartbeat. Your heart is a muscular organ that acts like a pump to continuously send blood throughout your body. Your heartbeat occurs when the atria and ventricles work together, alternately contracting and relaxing to pump blood through your heart.The electrical system of your heart is the power source that makes this possible.our heart is a muscular organ that acts like a pump to continuously send blood throughout your body.
