Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.
Where is blood pressure the greatest?
Each time the heart beats (contracts and relaxes), pressure is created inside the arteries. The pressure is greatest when blood is pumped out of the heart into the arteries. When the heart relaxes between beats (blood is not moving out of the heart), the pressure falls in the arteries.
Where is blood pressure the highest and lowest?
Blood flows through our body because of a difference in pressure. Our blood pressure is highest at the start of its journey from our heart – when it enters the aorta – and it is lowest at the end of its journey along progressively smaller branches of arteries.
What blood vessel has the highest blood pressure?
Important: The highest pressure of circulating blood is found in arteries, and gradu- ally drops as the blood flows through the arterioles, capillaries, venules, and veins (where it is the lowest). The greatest drop in blood pressure occurs at the transition from arteries to arterioles.
What state has the highest blood pressure?
One-third of U.S. adults have high blood pressure, but the rate varies widely from state to state, according to a new report from the Centers for Disease Control and Prevention (CDC). The state with the highest percentage of adults who said they have high blood pressure is Mississippi, with 35.9 percent.
Where does blood flow the fastest?
This value is inversely related to the total cross-sectional area of the blood vessel and also differs per cross-section, because in normal condition the blood flow has laminar characteristics. For this reason, the blood flow velocity is the fastest in the middle of the vessel and slowest at the vessel wall.
What has the greatest effect on blood pressure?
Blood pressure increases with increased cardiac output, peripheral vascular resistance, volume of blood, viscosity of blood and rigidity of vessel walls. Blood pressure decreases with decreased cardiac output, peripheral vascular resistance, volume of blood, viscosity of blood and elasticity of vessel walls.
How can I quickly lower my blood pressure?
Here are some simple recommendations:
- Exercise most days of the week. Exercise is the most effective way to lower your blood pressure. …
- Consume a low-sodium diet. Too much sodium (or salt) causes blood pressure to rise. …
- Limit alcohol intake to no more than 1 to 2 drinks per day. …
- Make stress reduction a priority.

What is the average blood pressure for a 70 year old?
The previous guidelines set the threshold at 140/90 mm Hg for people younger than age 65 and 150/80 mm Hg for those ages 65 and older. This means 70% to 79% of men ages 55 and older are now classified as having hypertension. That includes many men whose blood pressure had previously been considered healthy.
Is 150 90 A good blood pressure?
They’re both measured in millimetres of mercury (mmHg). As a general guide: high blood pressure is considered to be 140/90mmHg or higher (or 150/90mmHg or higher if you’re over the age of 80) ideal blood pressure is usually considered to be between 90/60mmHg and 120/80mmHg.
Do veins have high or low blood pressure?
Blood flows from the capillaries into very small veins called venules, then into the veins that lead back to the heart. Veins have much thinner walls than do arteries, largely because the pressure in veins is so much lower. Veins can widen (dilate) as the amount of fluid in them increases.
Does blood flow faster in arteries or veins?
Blood Flow
Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins. The rate, or velocity, of blood flow varies inversely with the total cross-sectional area of the blood vessels. As the total cross-sectional area of the vessels increases, the velocity of flow decreases.
In which blood vessel type is blood pressure the lowest?
In the general circulation, the highest blood pressure is found in the aorta and the lowest blood pressure is in the vena cava.
Is it possible to live long with high blood pressure?
If left untreated, a blood pressure of 180/120 or higher results in an 80% chance of death within one year, with an average survival rate of ten months. Prolonged, untreated high blood pressure can also lead to heart attack, stroke, blindness, and kidney disease.
What is normal blood pressure by age?
What is normal blood pressure according to age?
| Age | SBP | DBP |
|---|---|---|
| 21-25 | 120.5 | 78.5 |
| 26-30 | 119.5 | 76.5 |
| 31-35 | 114.5 | 75.5 |
| 36-40 | 120.5 | 75.5 |
What are the warning signs of hypertension?

- Severe headaches.
- Nosebleed.
- Fatigue or confusion.
- Vision problems.
- Chest pain.
- Difficulty breathing.
- Irregular heartbeat.
- Blood in the urine.
