ANATOMY

Detailed explanation-1: -Movement means artery health improvement And in response to regular exercise, they actually grow more blood vessels by expanding the network of capillaries. In turn, muscle cells boost levels of the enzymes that allow them to use oxygen to generate energy.

Detailed explanation-2: -Your heart will beat faster, which increases blood flow to your muscles. Your small blood vessels will widen to deliver more oxygen to your muscles and carry away carbon dioxide and other waste products that build up. It is this widening of the blood vessels that causes the flushing of your skin during exercise!

Detailed explanation-3: -The sweat evaporates, transferring heat energy from the skin to the environment. Blood vessels leading to the skin capillaries become wider-they dilate-allowing more blood to flow through the skin and more heat to be lost to the environment. This is called vasodilation .

Detailed explanation-4: -It looks at the role of adenosine triphosphate, or ATP, a chemical that can be released by red blood cells and is believed to cause blood vessels to dilate during exercise, when muscles demand more oxygen.
