Your heart is the pump for your circulatory system. It is made of muscle and contracts in order to pump blood through your body. The arteries and veins are the roadways through which blood is transported to all parts of your body. Arteries carry oxygen-rich blood from your heart to the rest of your body.Veins return the blood to the heart after the oxygen has been used. Your body needs oxygen in order to function.he arteries and veins are the roadways through which blood is transported to all parts of your body.

This process recycles NADH to NAD + so that NAD + can be reused in glycolysis. At the end of the ETC, water (H 2 O) and ATP is made. Depending on how many NADH molecules are available, the electron transport chain makes a total of 32 or 34 ATP.
SImple sugars (carbon chains) are dismantled and broken down to create ATP and NADPH. Glycolsis (simple sugars) are used to create the NAD molecules and the ATP. Source(s):
