Resistance also influences <u>total</u> blood flow. Resistance is defined as the amount of <u>friction</u> the blood experiences as it travels through the blood vessels. Blood flow is always <u>opposed</u> by resistance. Friction is due to the contact between <u>blood</u> and the blood vessel wall. The term <u>peripheral resistance</u> is typically used when discussing the resistance of blood in the blood vessels (as opposed to the resistance of blood in the heart). Several factors affect this friction, including blood <u>viscocity</u> , blood vessel <u>length</u> , and the <u>size of the lumen </u>of blood vessels (as indicated by vessel radius).
