Heart

ThE baby has died.

Not at all. The baby has a slower heartbeat when it is forming, don't you worry it will more than likely skyrocket up to somewhere between 120-170 in the next couple weeks :) Starting at week 5 the fetal heart will accelerate at a rate of 3.3 beats per day for the next month. The fetal heart begins to beat at approximately the same rate as the mothers, which is 80 to 85 bpm. Below illustrates the approximate fetal heart rate for weeks 5 to 9, assuming a starting rate of 80 Week 5 starts at 80 and ends at 103 bpm Week 6 starts at 103 and ends at 126 bpm Week 7 starts at 126 and ends at 149 bpm Week 8 starts at 149 and ends at 172 bpm At week 9 the fetal heartbeat tends to beat within a range of 155 to 195 bpm. The fetal heart rate will begin to decrease and generally will fall within the range of 120 to 160 bpm by week 12

the heart will get its supply of blood from the coronary artery. there are two coronary arteries in our body, the left and right coronary artery. each of these will set up small branches to supply blood and oxygen to different part of the heart. if one of these arteries get blocked, part of the heart muscle will not get enough oxygen and the person will suffer from heart attack.

Simply saying heart is a pumping organ , which pumps blood into the whole part of the body. The oxygen from lungs dissolve in it and the cells get oxygen through this circulation of blood. Food get digested and cells get food through the blood. thus the cells live with the help of heart. Our body is made up of cells and the cells live with the help of heart means the whole body live with the help of heart

Right atrium then right ventricle.

An adult (healthy) human heart weighs between 250 and 350 grams (one half - to - three quarters of a pound).

The heart weight usually gets larger with increased body weight/fat, and/or various types of heart damage.

The thick muscle layer of the heart is the myocardium. It is the middle layer of the heart and produces pressure.

Oxygen travels through the respiratory system. First, it enters through the mouth or the nasal cavity. Then, it goes down the trachea, or the windpipe, and into the lungs, where it is brought into the blood by the alveoli. Carbon dioxide is also exiting out of the body through the same way, but backwards.

An artificial heart is made from metal and plastic, and has a small pumping chamber lined by a special material that stops blood clots forming. An artificial heart that provides an extra ventricle to help pump blood around your body.

The heart is considered a double pump because the right ventricle of the heart sends blood to the lungs, and the left ventricle sends blood throughout the rest of the body. The atrium divides these two ventricles.

Your Brain will function for at least 6 to 7 minutes after your heart has stopped.

You have to be more specific about what you are doing but your heart beats to pump blood and oxygen to all parts of your body the more physical the activity the more blood and oxygen the body needs

The first successful open heart surgery was performed on July 9, 1893, when Dr. Daniel Hale Williams opened the chest of a man and repaired the pericardium (sac surrounding the heart) which had been damaged by a knife stabbing. The patient recovered after 51 days and lived for another 50 years.

Yes, thyroid dysfunction can sometimes result in heart palpitations, bradycardia and tachycardia. However there are many types of arrythmias and not all are the result of thyroid dysfunction.

When the thyroid is overactive it releases more thyroxin. Thyroxin, in a nutshell, tells your body how fast to go. If you have too much thyroxin stimulating your heart then it will beat faster.

Dr. Daniel Hale William-

James Cornish was dying. He had been carried into the emergency ward at Provident Hospital (which was founded by Dr. Daniel Hale Williams as the first segregated hospital) on Chicago's South Side, bleeding from a knife wound in his chest.

Dr. Daniel Hale Williams called for six of his fellow black physicians to help him get the dying man into an operating room. Carefully making an incision in his patient's chest, Williams exposed the man's still-beating heart and his near-fatal wound.

Williams and his surgeons sewed up the ragged gash located to the right of the heart, and, saying a prayer, sutured the chest incision, ending the world's first open heart surgery. The year was 1893.

Pericarditis is the inflammation of the pericardium, a two-layer membrane which is the sac surrounding the heart.
paracarduim inflamation is inflamation of the paracarduim which is a thin membranic sac that surrounds and prtoects the heart.

Around 36,000,000 every year, or around 2.52 billion times during 70 years.

In a whole lifetime there would be around 2,800,000,000 heart beats. But that depends what you are doing. Whether you are active or sleeping, the heart beats differ. The answer I got was if the person was sleeping their whole life.

The normal pulse rate range for a 1 mo-12 mo old child is 120-160 beats per minute (avg 140). For 12 mo-2 years it is 80-140 bpm (avg 120).

Keep in mind that our heart rates are slower during sleep and when it is cold. In contrast, if a child has a temperature, it can result in a faster heart rate. In those cases, it could be 7-10 beats off normal.

it will take a babys heart 40 days or 6 weeks to develop it will go through a phase called looping. Then when the baby is born after its first breath the valves in vetro are closed and the ones used in life open. Since the baby is using its owns lungs now. The last valve should close about a week after birth, leaving the 4 other valves open.
Really early on one of the first things that is formed is the beginnings of its heart and circulatory system. Once it starts pumping the blood starts flowing.

Let's follow the flow of blood starting at the Aorta, the aorta is the main blood vessle that carries O2 rich blood to the vital organs, organs, systems, extremities, muscles, and most importantly the brain. All the above mentioned use the oxygen and give off carbon dioxide as a by product. The CO2 , carried by the blood travels back to the heartand enters the Right Atrium, another beat of the heart, the b;ood now moves through the tricuspid valve to the right ventricle. Remember, this is oxygen poor blood so withamother beat the blood mooves through the pulmonary arteries, (left & Right), to the lungs. Inside the lungs the blood drops off CO2 and picks up O2 using a process called osmosis*. The blood at the moment has little pressure so it goes back into the heart through the Pulmonary Veins into the Left Atrium. A beat of the heart sends it into the Left Ventricle. Around this chamber is a large muscle called the Myo Cardium and this muscle gives the pressure needed to push this blood oround the entire body.

*Osmosis, the diffusion of water or another solvent through a selectively permeable membrane. This membrane is like a sieve, allowing solvent molecules, which are small, to pass through it, but preventing larger molecules dissolved in the solvent from passing through.

Blood is transferred throughout the body via the heart, this is called systemic circulation. The heart is made up of 4 chambers. The right atria, the right ventricle, and the left atria, and left ventricle. The right side of the heart gets the oxygen poor blood ( the blood that already cycled through the body). The oxygen poor bood enters the right atrim through the Superior vena cava and the Inferior vena cava. When the heart relaxes after a contraction then the blood leaves the right atrium, passes through the tricuspid valve (a flap that seperates the two chambers) and fills the right ventricle. When the ventricle is full the tricuspid valve closes. Now the blood is in the right ventricle, but it is so full the blood has to go somewhere so it pushes through the pulmonary valve and goes to the pulmonary artery then right to the lungs to be filled with oxygen. From the lungs the bood is now oxygen rich (filled with O2). The blodd leaves the lungs by the pulmonary veins and enters the left atrium, as the heart relaxes the tricuspid valve opens and the left ventricle fills with blood. When the left ventricle gets full the blood is pushed through the aorta valve and goes in to the aorta. From the aorta the blood enters into systemic circulation and spreads oxygen rich blood throughout the body. And when there is no more oxygen left in the blood it traveles back to the heart to start the cycle all over.

This is a difficult question to answer. Payment of surgeons depend on lot of factors 1. country of employment -US surgeons are paid better than Ugandan Surgeons 2.Private Sector paid better than Public. 3. Pay normally increases with number of cases done. 4. senior surgeons paid higher than junior surgeons. 5. reputed surgeons paid better etc.etc.etc.

The artificial heart is one of the most important developments in the medical field. It has saved many lives by acting to pump a patient's blood while they are waiting to either be fit enough for surgery or for a donor heart to become available.
