Hello there!
The answer is enzymes.
Enzymes are biological catalysts, which means they decrease the amount of activation energy needed to start a reaction, therefore speeding up the rate of the reaction. They are part of the protein macromolecule group. Without them, our bodies would not process things efficiently or fast enough for us to live.
Hope I helped. Have a nice day.
Blood distribution is adjusted by a short-term neural control mechanism to meet specific demands. During working out, the hypothalamus signals for reduced vasomotor stimulation of the skin vessels. Blood moves into the capillary veins, and heat radiates from the skin to reduce body temperature.
<h3>Veins</h3>
All over your body, veins are blood vessels that collect blood with low oxygen content and send it back to your heart. Your circulatory system includes your veins. They cooperate with your heart, other blood vessels, and other organs to maintain blood flow. Most of your body's blood is stored in veins. Your veins actually contain around 75% of your blood. Veins have two basic functions. One function is to gather blood that is low in oxygen throughout your body and transport it back to your heart. The other function is to transport blood that is rich in oxygen from your lungs to your heart. Only during this process do veins transport oxygen-rich blood.
Why does venous return from the distal arm travels in the superficial veins and those veins tend to bulge superficially in a person who is working out?
