Preventions: 0 | | If your veins are constricted, your heart has to pump harder to get the blood circulated and the pressure goes up because your heart is pumping harder. You wear out your heart. Decreased oxygen to the heart.Increased blood pressure and heart rate.Increase in blood clotting.Damage to cells that line coronary arteries and other blood vessels. | --------------------------------------------------

Preventions: 0 | | Question #1: Think about it. Vasoconstriction is a narrowing and tightening of the arteries. Your heart rate increases because nicotine is a stimulant and triggers the release of adrenaline (epinephrine). Your heart also has to work harder to pump the same volume of blood through arteries and arterioles smaller than the size they should be. There will be more force exerted against the arterial walls with every contraction. This force is the systolic blood pressure. The diastolic blood pressure is the amount of force exerted when the heart is at rest, between contractions. This is also likely to increase because the heart isn't really resting between contractions.Question #2: The chemicals in tobacco enter the blood stream along with oxygen molecules in the alveoli of the lungs. Nicotine thickens the blood and damages the walls of the arteries and arterioles. Uncontrolled hypertension also injures and damages arterial walls. Let's go back to adrenaline for a moment. Normally when adrenaline is released by the body, there's a fail safe that shuts it off if there's no continuing need for it (flight or fight, remember?) Nicotine interferes with that and the artificial stress situation continues. This, too, is hard on the body, hard on the blood vessels.Our blood vessels have a certain amount of elasticity and resilience but years of smoking causes so much interior damage, the arteries and arterioles can no longer function as they were meant to. | --------------------------------------------------

Preventions: 0 | | Vasoconstriction occurs.After 20 years of smoking I recently quit. Afterwards, I had to cut my BP medicine in 1/2 because it dropped 30pts.~ | --------------------------------------------------

Preventions: 0 | | How do these effects lead to high blood pressure? Why are cigarette smokers more likely to die of cardiovascular diseases than nonsmokers? | --------------------------------------------------
