Heart

No, some heart diseases can be cause by not eating properly, not enough exercise and stress.

The left atrium and right atrium receive blood coming into the heart.

Heart strings (scientific name chordae tendinae) are located in the heart. They are believed to brace and support the heart.

The bloody kind

Bundle of His
atrioventicular bundle (bundle of his), right and left bundle bramches and the purkinge conducition fibers

Its the difference between your systolic and diastolic readiing.

The design of the mammalian heat is that there are two chambers used to receive blood from, and pump blood to the lungs, and then two more chambers used to received blood from, and pump blood to the rest of the body other than the lungs. This arrangement works more efficiently than if there are only two chambers receiving blood from and pumping blood to the entire body including the lungs.

Males tend to be bigger than females, and have have a larger proportion of muscle mass. As a consequence, males need bigger hearts to supply the bigger amount of muscle.

The kidney can begin to fail if the disease or injury is serious. If they completely fail. then a person would have to have dialysis treatment. This treatment is only found in advanced societies. The person would die without this treatment.

Yes, but only for a short time. You can stay alive for 3 minutes after your heart stopped beating. 3 minutes is all you get. So live close to a hospital in case when you get old.:)

Roll the air drying clay out to about 1/8 thick on a flat work surface. Trace a heart shape onto the clay with the toothpick. Use your fingers to rub away any mistakes until you get a good heart. Cut the heart out with the toothpick or butter knife. Smooth the edges of the clay with your fingers. Dip your fingers in water to help smooth the clay. Punch a hole in the top middle of the heart with the toothpick. This will be the hole for the necklace to go through. Allow the clay to dry for 24 hours. It must be completely dry to paint. Paint the clay heart pendant with acrylic paint. Allow this to dry. Spray on a coat of clear acrylic spray paint to seal the first layer of paint. Add up to three more coats of clear paint. Cut out a piece of leather twine or yarn to 30 inches long. Thread one end of the twine through the hole in the heart pendant and tie the two ends together. You can make this necklace any length you want.

Sadly while their body can continue to go on with the help of machines, their mind, their personality, and all other parts of them mentally are already gone. Once a doctor has pronounced a person brain dead he is sure of his findings and this is something that cannot be reversed. There is no blood flow in their brain and their brain does not react in any way to stimulation. A quick way to see if someone may be brain dead is shining light into their eyes; a person who is truly brain dead does not have a pupil response. Eventually this person who is brain dead is let off of machines which keep their body alive and their body dies as well. Hopefully, if the person is able to give organ donations they do so, because they could be saving other's lives.

No, it is oxygenated. Pulmonary veins are the only veins in the human body that carry oxygenated blood.

Heart is located at the left midclavicular line at the 5th intercostal space. it is where your PMI or point of maximal impulse can be heard.

There are many ailments of the heart. One ailment could be that the mitral valve doesn't function. A person could also have blocked arteries or their heart might be too small.

because less pressure is needed to pump the blood to the lungs as oppose to the left side which has the duty of pumping the blood to the body. and also due to the fact that the blood coming to right side of the heart from the body very low pressure

Back to the lungs via veins to be re-oxygenated

epicardium

yes. the atria are on the top and the ventricles are on the bottom

No its actually in the middle if your chest :)

The largest part of the heart is the left ventricle. The left ventricle (lv)is the strongest part of the heart. If you think about it the lv is one of the most important chambers of the heart because it pumps the blood to the aortic sl valve which goes to the aorta. The aorta supplies the body with oxygen rich blood and it is very important that the body has oxygen without o we would not be able to function.

pleural space

The heart has only one major function. This function is to pump blood through the body and to and from the lungs.

The human heart is only about 5 inches in length. It weighs about 200 to 400 grams, depending on the age, weight and build of the person. Typically, an adult heart is about 300 grams.

If you want to find out what size your heart is, clench your fist. The sized of the heart is roughly equal to the size of your curled fist.
