Why does your heart beats fast and slower when you are standing still?
Heartbeat is regulated according to the energy requirements of the body. When you are standing still, you do not expend as much energy as you do when you are running or walking, so your heart rate would be slower. When you are supine/prone during sleeping, your heart rate falls further because your metabolic processes also slow down.

Does the parasympathetic nerve acts as a braking system for the heart?
the heart is supplied by both sympathetic and parasympathetic nerve fibers . normally in resting state the heart is under the parasympathetic stimulation ; that's mean if you ramove the parasympathetic stimulation the heart rate will increase up to 100 beat by minute ( under normal conditions in healthy man the heart rate is 72 on average ) , during exercise the heart rate increase and that occurs by the sympathetic stimulation and decreasing the parasympathetic stimulation , and that exactly resemble what occurs when you increase the car velocity : so the we can say that the parasympathetic nerve acts as a braking system of the heart .written by : asma aburas ; medical student .
How many tubes the heart has for blood to go out?
There are two tubes that take blood out of the heart. These are the pulmonary artery and the aorta.
How can heart disease damage your heart?
Heart disease can damage the heart in different ways depending on the disease. In CAD (Coronary Artery Disease), blockages in the lumen of the arteries can cause areas of the coronary muscle to shut down due to lack of oxygenation. If the plaques continue to build up in the heart's blood vessels, more coronary muscle shuts down. Undetected, this could lead to death as the heart does not have the strength to pump blood through the body.
How long do you have in a heart attack before you die?

Not authentic. The WELLS FARGO marking is wrong, and actually very very few were company marked. Local office managers would purchase whatever was available and issue the guns to the messengers without markings. Probably less than 100 were ever purchased by the company itself and marked. Value would be minimal.

No. Veins carry blood to your heart and arteries carry blood away.
Arteries carry blood away
What is the movement of blood around heart tissue called?
The movement of blood to the heart tissue is called myocardial perfusion. In order for the myocardium (the heart muscle) to get oxygen and nutrients it has its own circulation providing a blood supply known as the coronary circulation. The coronary arteries (oxygenated blood vessels of the heart) supply nutrients and oxygen to the heart muscles between heart beats when the heart is relaxed (during diastole). Blood is routed from the surface of the heart muscle to deeper tissues of the myocardium. After delivering oxygen and nutrients to the cells of the heart, coronary veins pick up the blood and route it into the pulmonary (lungs) circulation where it can become re-oxygenated and return oxygenated blood back to the heart.
No, the parasympathetic n.s. will slow the heart down, the sympathetic n.s. will increase heart rate.
What type of blood vessel carries carbon dioxide away from the cell?
Capillaries carry carbon dioxide away from cells where it reacts with water to form a bicarbonate ion which is more dissolvable in blood than CO2.
