When you exercise, the muscles cells consume energy. This energy is provided in the form of respiration and digestion, supplied by the blood. When the energy is used, it needs to be replaced quickly, so the heart beats faster. As it moves faster, you need to breathe deeper and faster to supply the fast flowing blood and to cool down the body from the excess heat created by the exercise
It's not good at all.
The nervous system causes the heart to beat faster when you exercise. It itself is not an organ but a system.

when we exercise our heart beat increases due to the reason that during exercise the body need more oxygen which is carried by blood so more and more blood carrying oxygen is to move to the part for which we are doing exercise and so more of the work heart have to do to pump the blood so ultimately our heart beat increases
That depends on the nature of your exercise. Heart beat rises to meet your metabolic requirements. Normally the heart rate goes up to 100 to 160 per minute. It may go up to 180 beats per minute in severe exercise.
Your heart starts to beat at faster rate. The heart rate may go up to 180 beats per minute.
A lower resting heart rate is an effect of exercise and as an athlete is more likely to exercise more regularly then their resting heart is likely to be lower.
