Heart

Brave

Your heart makes the thump thump

The average heart beats around 345,632,391,283 times per lifetime according to average dieing age of 85.

As heart beats faster, it uses more and more energy to and sends more oxygen to body, When heart beats faster to pump more oxygen to the muscles, brain signals lungs to inhale and exhale with the greater frequency, thus obtaining more and more oxygen, this process of the oxygen based energy production is called aerobic respiration.

Heartstrings are found in the heart's valves. Heartstrings are cords that wrap a graph to the aorta. Love pains were also known as someone pulling at your heartstrings. See the related link for more information.

Males are physically bigger and stronger than females and as such all the organs and bones of males are always bigger in comparison to females

I am not a medical professional but as a knowledgeable layperson (first diagnosed with intermittent atrial fibrillation in 1998 and having a pacemaker since Aprol of 2008) I will try to answer.

First off, the word is "defibrillator"; so called because it shocks the heart in attempt to "reset" the primary pumping chambers of the heart (the ventricles) in order to stop them from "fibrillating" - i.e. randomly twitching instead of producing a coordinated beat. If your ventricles are fibrillating then your heart is not pumping your blood. If that condition is not corrected within approximately 3 minutes your brain starts to die. Not long after you will be clinically dead.

No device is actually implanted IN your heart. The device is implanted under the skin of your upper left chest slightly below your collar bone. An implantable device does the same thing the big paddles you see being used on medical programs. The only difference is that instead of having to send the electrical energy through your skin and chest wall, the electrical current is conveyed through small wires threaded through the main return vein into your heart. It takes a WHOLE lot less energy to shock the heart from inside than from outside your body. A device to shock your heart from the inside is called an Implantable Cardiac Defibrillator (ICD).

Whether or not to have an ICD implanted is a question for you and an electrophysiologist (EP)to answer. EP is a sub-specialty of Cardiology concentrating on electrical problems of the heart. I love my EP to death and would do anything in the world for him.

The first person to ask about this is your Cardiologist. If you are not already working with a Cardiologist then why are you asking such a question? But if you do not have a Cardiologist then you need to get your Primary Care Doc to recommend a good one. Ask him/her who they would refer their CHILDREN to.

in heart.

Indirectly, yes. All veins flow back to either the superior vena cava or the inferior vena cava and into the heart.

No.

It means that it is having trouble pumping the blood efficiently.

the routine measurements that could be taken to monitor the functioning of asthma is peak flow measurement.

The right ventricle

Chordae tendinae are the string-like structures that attach to the AV valves of the heart.

the spirtial node

Blood is forced into the ventricles each time the atria contact.

*do you go to Smith Language Academy because we had the same question on our extra-credit. :-)

The earliest a doctor can get a baby's heartbeat on a Doppler inside the womb is 9 weeks... any earlier and it might not be able to be heard! Hope this helps... on the flip side you should take into account your size. If you are smaller it might happen sooner and if you are larger than it may happen a little later.

The location of the heart is in the mediastinum !!between the lungs & above the diaphragm

The Ancient Egyptians left the heart in the body so that it could be weighed in the afterlife by the god Anubis. It was to be weighed against the feather of truth to determine whether the deseased lived a good life and was able to procide into the afterlife. If the feather and the heart were balanced the deseased would go to live in the afterlife. If they didn't balance, the heart was fed to Ammit, the Devourer of the Dead. The deseased would go no further.

Also because the Egyptians believed that the heart was the center of the body. That's also why they took out the brain.

When muscles are used for exercise, they must be replenished with oxygen, nutrients, etc. They also produce waste products that need to be taken away from the cells. Blood is the transport system for all of these things, so the harder your muscles are worked, the quicker they burn through nutrients and produce waste, meaning that the blood must flow faster to provide all of this; the only way for blood to flow faster is for your heart to beat faster.

Resting muscle gets about 750 ml of blood out of your 5 liters of cardiac out put. During exercise the cardiac output may go up to 25 liters per minute. Out of these 25 liters of cardiac out put, your muscles get about 20 liters of blood to meet the metabolic requirements of oxygen and food material. The stroke volume of heart increases but then heart rate also increases from 72 per minute to up to 180 beats per minute.

the heart muscle is enclosed by the 3 layers of tissue.the closest to the heart is the visceral layer of serous pericardium then parietal layer of serous pericardium and then the fibrous pericardium
