@instituteofhumananatomy: PART 1: Why Blood Pressure Could Literally Save Your Life Blood pressure gets checked at nearly every doctor visit for a reason - it's called the "silent killer" because high BP can damage your body for years without symptoms. THE GOLDILOCKS PRINCIPLE: Your blood pressure needs to be just right. Too low = tissues don't get enough oxygen. Too high = pressure damages blood vessels and organs over time, leading to stroke, heart attack, kidney failure, and aneurysms. WHAT IS BLOOD PRESSURE? The force of blood pushing against your artery walls as your heart pumps. Think of water pressure in a hose - blood does the same thing to your arteries. THE EQUATION: Blood Pressure = Cardiac Output × Systemic Vascular Resistance CARDIAC OUTPUT: How much blood your heart pumps per minute (influenced by heart rate and how forcefully it contracts) VASCULAR RESISTANCE: How much your blood vessels resist blood flow - affected by: +Artery constriction/relaxation +Blood vessel length +Artery compliance (stretchiness) WHY HEALTHY ARTERIES MATTER: Looking at this real aorta, you can see how it stretches and recoils when blood enters. This elastic "bounce back" helps push blood forward without extra work from your heart. Diseased, stiff arteries lose this ability, forcing your heart to work harder and raising blood pressure. This is why cholesterol and plaque buildup is dangerous - it doesn't just block arteries, it makes them rigid. Coming up in Parts 2 & 3: What your numbers should be and how to lower high blood pressure naturally. #BloodPressure #Hypertension #HeartHealth #CardiovascularHealth #HealthEducation #PreventiveCare
