Blood pressure is directly proportional to blood viscosity.
Blood pressure is inversely proportional to blood flow.
As a blood vessel dilates, the blood pressure increases.
(BP is directly proportional to peripheral resistance - vasodilation decreases PR)
Hypertension is called a “Silent Killer” because it damages the walls of arteries and arterioles.
(hypotension is not usually considered a major health risk)
ALL veins carry blood to the heart and ALL arteries carry blood away from the heart.
(remember: arteries = away)
The pulmonary arteries carry oxygenated blood from the lungs to the left atrium.
(the pulmonary VEIN carries oxygenated blood from the lungs to the left atrium)
