What happens when the resting heart rate must suddenly do exercise?
it gets scared cause it doesnt excercise at all so it freaks out when you start moving.
How many times does a heartbeat in a minute while resting?
the always beats resting or not, if it stopped you would die. But assuming you mean how often does it beat during rest. Well that depends on how fit you are. Someone, like a runner, who does a lot of Cardio-vascular exorcise (gets the heart pumping fast) will have stronger heart muscles than some one who sits around all day. This means that their heart doesn't need to beat as fast as it can push more blood around the body in one pump than the other persons. for the average healthy (but not fit) man its 64-72 beats per minute at rest and for the Average healthy Woman around 72-80 BPM
What can be done to improve a weak heart?
with excercise. When your heart gets pumping hard from physical activity, it gets stronger because it's a muscle, and muscles get stronger with use (not just picking up your coffee kind of thing, but like really using them like you do when you excercise).
How does alcohol affect the heart?
Causes it to dilate and thus release heat. That's why after drinking, your face gets red, because the blood vessels rise to the surface of the skin, and you may feel hot because it's giving off heat.
Why is the aorta at the top of the heart?
to be closer to the brain which gets 1st dibs at oxygenated blood after the heart itself
