Answer:
The reason is because the heart requires more oxygen when exercising. Several physiological events happen to increase the blood flow and therefore oxygen flow to that muscles,including the heart.
Also the volume of blood that the heart pumps out is maintained so that the body organs receive the necessary amount of oxygen and nutrition, because if it didn't adjust the flow of blood to match activity level, you will be insufficient. Either output method will be lower than needed.

Guns are cool but vilonce is not
Explanation:
Guns in Amerca are mostly used for recreation purposes but people do use them for bad things, And the people who do that, most of them got their fierarms illegaly. In fact, In america guns are used to save the lives of 500,000 to 3 million people each year by legal-firearm-owning Americans. According to the FBI. Their are also about 30,000 deaths related to fierarm involved crimes, so more crimes are stopped than killed with firearms. From my experiences with anti-gun activists is that they don´t know stuff about firearms. I know alot of people who think fully-automatic weapons are leagal. They are not. My point is, if you don know about somthing, dont pretend you do. thats just like me trying to ban keybord manufacturing when I don´t know nothing about the keybord industry. I reccomend you go to your local gun-shop and purchase a firearm, just a cheap one and see the back-ground check proccess. You might even not need to buy one, just aske them if you could see the background check proccess.
