The brain doesn't control the heart. The heart controls itself. If you would take a single heart muscle cell, it will beat on its' own. Add another and they beat together. The heart has special muscle cells called pacemakers. The primary one is called the SA (sinoventricular) node. That sets that pace or rhythm. There is also a slower back up pacemaker called the AV (atrial ventricular) node.
The brain has automatic processes that send signals to the heart that in turn cause it to contract in a rhythmic fashion, pumping the blood.
This means that there is blood in the pericardial sac which is around the heart. This problem restricts the natural movement the heart makes when contracting and relaxing.

The phrase "does the heart affected" makes no sense.
Your heart beating (The muscles in the heart relaxing and contracting) to pump the blood around your body, without which you would die. Your pulse is the blood rushing through your veins after each 'pump', hence you can feel your pulse.
The adrenal medulla is the part of the brain responsible for the release of adrenaline, when the adrenaline is released into the blood, the SAN is stimulated to work faster and increase your heart rate, this happens when playing sport or during your fight or flight response. However, the heart is not controlled by your brain as it is a myogenic muscle (self-exciting) this means that if you were to remove the heart from a body it would continue to beat. The sino-atrial node is responsible for the excitation of the heart. :) Hope this helps. Steph :)

because the heart pumps the blood around the body and the pulse there is blood and the blood comes from the heart so heart controls the body second after the brain,let me explain it in this waay in the pulse there is bloood and the blood makes the bump and weher does the blood come from the heart that is a why they pump together and you breath at the same time
the heart beating the blood around the body
Yes, the brain is supplied with blood that carries oxygen.
Your heart, and oxygen that makes the brain make the heart pump. The veins and arteries ... some of them constrict to make blood move through the body.
the valve in the heart makes sure that blood moves around your body, it also makes sure that the blood travelling around your body is travelling int he right direction.
More blood is pumped around the body because the heart beats more. When the heart beats more the that makes the blood move around the body faster :)
When the heart pumps blood around the body it makes more blood available to all parts of the body, including the muscles
The contractions and relaxation of the muscles in the heart cause the blood to be pumped around the body. The contractions push the blood out of the heart and cause it took be pushed around the body in 0.8 seconds. Other muscles in the heart relax so blood may flow into another chamber of the heart.
This means that there is blood in the pericardial sac which is around the heart. This problem restricts the natural movement the heart makes when contracting and relaxing.
