Study Notes
Understanding the Circulatory System
- Heart: The central organ that pumps blood throughout the body
- Blood Vessels: A network of tubes (arteries, veins, and capillaries) that carry blood
- Blood: The fluid that circulates, transporting oxygen and nutrients, and removing waste
Anatomy of the Heart and Blood Vessels
- Arteries: Carry oxygenated blood from the heart to the body
- Veins: Carry deoxygenated blood back to the heart
- Capillaries: Tiny vessels connecting arteries and veins, enabling gas exchange
Systolic and Diastolic Blood Pressure
- Systolic Pressure: Pressure when the heart beats, indicating force of blood pushing out
- Diastolic Pressure: Pressure when the heart rests between beats, reflecting pressure during heart filling
Normal, Pre-hypertension, and Hypertension Ranges
- Normal: Systolic less than 120 mmHg, Diastolic less than 80 mmHg
- Pre-hypertension: Systolic 120-139 mmHg, Diastolic 80-89 mmHg
- Hypertension: Systolic 140 mmHg or higher, Diastolic 90 mmHg or higher
Factors Affecting Blood Pressure
- Age: Blood pressure tends to increase with age
- Genetics: Family history of hypertension increases risk
- Lifestyle: Diet, exercise, smoking, and stress can influence blood pressure
- Medical Conditions: Conditions like kidney disease or thyroid problems can affect blood pressure
Techniques for Accurate Blood Pressure Measurement
- Preparation: Sit quietly for 5 minutes before measurement
- Arm Position: Rest your arm on a table at heart level
