Modern firearms use the same principles as muzzleloading firearms. The ignition and burning of gunpowder create pressure. This pressure propels projectile(s) down the bore and out of the muzzle. The first modern firearms used black powder. Since about 1890, modern firearms are designed to use smokeless gunpowder. Smokeless gunpowder creates greater pressures and should not be used in firearms designed for black powder. Watch what happens when the trigger is squeezed on this bolt action rifle.

Explanation:
Epinephrine is also known as adrenaline. It’s both a <u>hormone</u> and a <u>medication</u>. While cortisol, estrogen and growth hormone are key to muscle and bone formation, epinephrine has other functions. It’s released by the adrenal glands and some neurons in response to danger, excitement and stress. Epinephrine helps the body react to those emotions more quickly. It increases strength and awareness in stressful situations. It makes the heart beat faster and increases blood flow both to the brain and muscles. In excess it can be dangerous to the body.
