Why during the ventricular systole the left ventricule is the first to begin contracting but the right ventriculeis the first to axpel blood?

before either ventricule can expel blood, the pressure inside must exceed the pressure in the artery leading out of it, and the systemic pressure is normally much higher than the pulmonary pressure.

What heart diseases lead to valvular heart disease?

What makes someone able to feel their heart beat in their toe?

You can feel your heart beat (faintly) in your toe because there are blood vessels and capillaries (very very small blood vessels) all throughout your body, including your toe. These blood vessels are actively channeling blood throughout your body like hoses, and the heart is the pump pushing it through. You can feel you heartbeat best right after a jog or good session of exercise especially if you haven't had your bottle of water. Other regions where your heartbeat is best felt and/or measured are the carotid areas (right below your jawline) your brachial arteries (on either arm just past the armpit and before the elbow) and your femoral arteries (right on your pelvic bones (hip bones)).

Typically, heart rate increases with inhalation. It is not normal for the heart to slow down with inhalation.

Explain the procedure that is taken place for heart plantation?

What does slippage in pumps mean?

Slippage in pumps refers to the difference between the actual flow rate of fluid being pumped and the theoretical flow rate expected based on the pump's design. It occurs when some of the fluid leaks back or bypasses the impeller or other components, reducing the efficiency of the pump. Factors contributing to slippage can include wear, improper alignment, or issues with seals. Monitoring slippage is crucial for optimizing pump performance and ensuring reliable operation.

What is the heart controlled by?

The heart is controlled by the "Cardiac" Muscle

Without it our hearts would not be able to beat.

Where can one listen to 'Stop crying your heart out' by by Oasis?

These are just a few of the hundreds of attributes cataloged for this track by the Music Genome Project. You can find it at Pandora, Myspace, Youtube and last.fm.

Is an event in which the heart abruptly stops or develops a very abnormal arrhythmia that prevents it from pumping blood?

Heart failure is an event in which the heart abruptly stops or develops an abnormal arrhythmia that prevents it from pumping blood. It is a chronic condition in which the heart is unable to pump out all of the blood that enters it.

What starts a baby's heart?

DC

The heart forms after about 22 days(not complete but starts to receive blood). Because it is linked to the mothers blood supply its starts to pulse with the mother's heartbeat. Meanwhile heart tissue/muscle is still forming while the babies heart is still pulsing from the mothers heartbeat. At some stage the nerves from the babies heart get connected to his own brain and start to beat on its own as it receives the signal from his brain. First very weak, but as the nerve connection gets better, it starts to beat stronger up to the stage that you as the mother can feel/hear it.

What system is the ventricle in?

Do leeches have heart chambers?

How do you set valve clearances onmazda BT50?

To set the valve clearances on a Mazda BT-50, first ensure the engine is cold and remove the valve cover to access the valves. Rotate the engine to the TDC (top dead center) position of the first cylinder on the compression stroke. Using a feeler gauge, measure the gap between the rocker arm and the valve stem, adjusting the clearance by tightening or loosening the adjusting nut as needed to achieve the specified clearance. Finally, recheck the clearance and reassemble the valve cover.
