Heart

If you like and love the job you will surely do the jod efficiently..

Once you heart stops working you brain will die soon for lack of oxygen.

You could say that, but you could say it functions as two pumps or one. As four pumps the (1)left and (2)right atrium pump blood into the left and right ventricles. Then the Left and Right ventricles pump blood into the (3)lungs and (4)body respectively. Looking at the heart as two pumps, the atriums (L and R) pump into the ventricles. As one pump, the heart circulates the blood in the body.

The left and right ventricles of the heart receive the blood from the left and right atria respectively. The ventricles then send blood into the arteries. So technically they send and receive, but I guess their main functions is to send blood to the body and lungs.

no, otherwise the SA Node wouldn't be able to control the contraction of the heart

When the smaller, upper atria chambers contract in the first phase of systole, they send blood down to the larger, lower ventricle chambers.

Open so the ventricle can receive more blood to pump.

Narrowing of the heart valves can be detected more accurately by auscultation than by electrocardiogram. That's because it takes a closer visual. An electrocardiogram just takes readings.

Atria receive blood into the heart and ventricles "discharge" it from the heart

Capillaries are the smallest of the blood vessels. Their thin walls and small size facilitate gas exchange with the body tissues.

Your heart is located in your chest . And always will be . ( If you put your hand on your chest and hold your breath , you can feel your heart pumping . )

70%

the remaining 30% is pushed into the ventricles during atrial systole

A heart will beat for a little while until your brain shuts down.

Organs in the body are not directly connected to the heart. The heart pumps the blood through the circulatory system. The blood goes from the heart, to the arteries, to the capillaries, to the veins and back to the heart. These arteries, capillaries and veins run all through out the body to every organ to supply the body with blood. Even thought the heart is not directly connected to the organs its connected to every organ via arteries and veins.

Yes. A sharp or persistent pain from shoulder to under the ear can be one of the signs of a heart attack. It is not usually the only indicator but if you are concerned, seek medical attention at the nearest emergency room.

A technician knows the valves are timed properly by ensuring that the timing marks on the camshaft and crankshaft align according to the manufacturer's specifications. They may also check for proper valve clearance and observe the sequence of valve opening and closing in relation to the piston position using a timing light or diagnostic tools. Additionally, conducting a compression test can help confirm that the engine is functioning correctly, indicating proper valve timing.

A vessel called the ductus arteriosus (aka ductus Botalli) connects the pulmonary artery to the aorta in a developing fetus. Along with the foramen ovale, the hole connecting the fetal atria, this opening allows venous blood to bypass the non-functional lungs of the fetus and be pumped back into the arteries. Until birth, the oxygenation of fetal blood is through the umbilical cord.

In 2009, an estimated 785,000 Americans had a new coronary attack, and about 470,000 will have a recurrent attack. About every 25 seconds, an American will have a coronary event, and about one every minute will die from one (CDC).

The endothelium is the medical term meaning lining of the blood vessels, including those of the heart. It is continuous with the endocardium, the inner lining of the heart chambers and heart valves.

We need our heart because it pumps blood through our body. When it does, the blood goes to all the body so every part gets all the blood that is nesessary.

The bulk of the heart rests on the Left side of this heart.

In a healthy person, the left ventricle should be slightly larger than the right ventricle. The left ventricle has to pump with enough force to eject blood through the entire body (except the lungs). The right ventricle, on the other hand, only needs to pump with enough force to eject blood to the nearby lungs.

If you lift heavy weights with your left arm and light weights with your right arm, your left arm will become bigger than your right arm. In a similar manner, the left ventricle is larger than the right ventricle.

Extreme differences beyond what is normal could signify a pathological condition that is causing more resistance to the flow of blood out of the heart. For example, if the right ventricle becomes much larger than what is typical, it could mean that the pulmonary valve is stenotic (acting like a kink in a hose). This added resistance to flow makes the right ventricle work harder. When a muscle works harder, it grows (hypertrophies) to compensate.
