Study Notes
Blood Pressure and the Circulatory System
- Blood pressure measures the force of blood against artery walls as the heart pumps.
- The circulatory system consists of the heart, blood vessels, and blood.
- The heart pumps blood throughout the body.
- Blood vessels are a network of tubes carrying blood: arteries, veins, and capillaries.
- Arteries carry oxygenated blood from the heart.
- Veins carry deoxygenated blood back to the heart.
- Capillaries are the smallest blood vessels connecting arteries to veins.
Blood Pressure Measurement
- Systolic pressure measures pressure when the heart beats.
- Diastolic pressure measures pressure when the heart is resting.
- Normal blood pressure is less than 120/80 mmHg.
- Pre-hypertension is 120-139/80-89 mmHg.
- Hypertension is 140 or higher/90 or higher mmHg.
Factors Affecting Blood Pressure
- Age: Blood pressure increases with age.
- Genetics: Family history of hypertension increases risk.
- Lifestyle: Diet, exercise, smoking, and stress can influence blood pressure.
- Medical Conditions: Certain conditions like kidney disease or thyroid problems can impact blood pressure.
Techniques for Accurate Blood Pressure Measurement
- Sit quietly for 5 minutes before measurement.
- Rest your arm on a table at heart level.
