    Study Notes

    Cardiovascular Physiology

    • Diastole: Period when the heart ventricles are relaxed.
    • Systole: Period when the heart ventricles are contracting.
    • Blood Pressure: Force exerted against artery walls as blood is pumped, classified as systolic (>120) and diastolic (>80).
    • Peripheral Vascular System: Comprises arteries, arterioles, capillaries, venules, and veins that carry oxygen-rich blood from the heart to tissues, facilitate gas exchange, and return carbon dioxide to the heart.

    Hypertension

    • Definition: High blood pressure, often termed HTN.
    • Risk Factors:
      • Changeable: Diet (high sodium, low potassium), obesity, smoking, excessive alcohol, stress, diabetes.
      • Non-changeable: Family history, age, genetics.
    • Symptoms: Known as "The Silent Killer," symptoms include vague headaches and blurred vision.
    • Complications: Can lead to damage in vital organs like the eyes, kidneys, heart, and brain.
    • Treatment: Includes monitoring BP and lifestyle modifications (diet, exercise, stress reduction).

    Hypertension Medications

    • Antihypertensives:
      • ACE Inhibitors: Block formation of angiotensin II, leading to vasodilation, reduced fluid volume, and lowered BP.
