yes it does. coffee has been scientifically proven to speed up the beating of the heart. the faster the heart beats, the more blood pumped through your lungs. blood carries oxygen, and oxygen helps asthma.

I know much about the heart. It's one of the most important organs in your body. (probably the most important if you want to stay alive). It is a very complicated system.\n\nYour question is too broad, I don't understand what you're trying to ask. Your question is more of an opinion one. If you have a particular question, I'd would be glad to answer.

As you exercise, your heart pumps harder and faster to compensate for the increase in oxygen intake and removal of toxins in your body (i.e. breathing). If you have a weak heart, it might not be able to keep up, and it will either pump too hard, stop pumping entirely, or skip a beat and then tries to catch up, causing a major coronary.

It raises your heart rate, try to limit your intake to 1 or 2 cups a day.  Your doctor should tell you to stop it completely if you have certain types of heart problems.

Inside his heart beats generosity.  Love, caring, and loyalty bleed through the veins that his heart drives.  \n\nPounding with pleasure, he begs for the attention that only you can give, and he yearns for the affection that only you provide.  \n\nInside his heart the chambers are empty.  The void your love fills.  \n\nInside his heart the muscles lay cold and weak, until your heart with his beats still.  \n\nAs one, your two hearts beat.  As he rubs his back against your feet.  His tail wags vividly to show you that your heart is what is inside his heart!\n\nArf Arf!

A heart is a pumping station, circulating blood is its main function. The idea is to utilize its throbs,synchronise God's name within. The constant repetition of God's name produces God's light. The heart,being a pumping station circulates the Light-oriented blood all over the body. As a result of thisnot only does the heart get enlightened but also the whole body.

Does your heart stop when you sneeze?\n– Lauren K, El Cajon\n\nNo. The heart's rhythm is controlled by a natural pacemaker – the sinoatrial node, a group of cells located in the right atrium of the heart. These cells create an electrical impulse by pumping charged particles out of the cell and then allowing them to flow back in. Conducting cells transmit the electrical impulse to all parts of the heart to initiate muscle contraction. Sneezing does not stop this electrical activity.\n\nHowever, the nervous system and circulating hormones, such as adrenaline, alter the rate of the electrical activity in the sinoatrial node to increase or decrease heart rate. Just as exercise leads to an increased heart rate, sneezing works many muscles; therefore it is possible for a "sneeze attack" to increase heart rate.\n--------------------\nSherry Seethaler has a doctorate in science education and is a UCSD science writer and educator.

Looking at the sites in our Heart category, your heart keeps pumping blood throughout your body from when you're a baby in your mother's womb until the moment of death. Your heart beats all day and all night, all the time. When you run or play hard, your heart beats faster. When you're asleep, your heart beats slower, but it doesn't stop. If a person needs heart surgery, doctors hook the patient up to a machine that pumps blood for the heart. Only then is it safe for the doctor to stop the heart in order to operate. When you sneeze, the muscles in your abdomen, chest, and throat are all involved. And, even though you might not notice it, your heart is working too.\n\nEarl

the heart generates its own electrical impulses to stimulate the heart to beat . It is the SA node in the atria and the AV node in the ventricles. \n\nWhen patients have been diagnosed as brain dead - and on a ventilator ( a breathing machine )  - their heart is still beating - because the heart has its own built-in battery pack, so to speak .

I think anything emotional has a physical effect on our bodies...just think of the chemical changes needed to change emotions...\n\nI really do "feel it in my gut" sometimes when something gets me riled up.\n\nThinking about past heart-breaks does make my chest hurt.\n\nHow 'bout U?

No.  The heart is just a muscle.  If you exercise, it beats more, but gets stronger and lasts longer.

Your heart is a pump that circulates blood through the many veins and arteries in your body...oxygenated blood leaves your heart ,in your arteries, flows to your tissues, organs and cells depositing oxygen then returns through your veins back through your lungs to heart to re oxygenate the the cycle starts over.
