The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

Sure! Let’s walk through each part of your request carefully and completely.<\/p>\n\n\n\n

\n\n\n\n

Trace a drop of blood through the heart and body:<\/strong><\/h3>\n\n\n\n
    \n
  1. Inferior & Superior Vena Cava<\/strong> \u2013 Bring deoxygenated blood from the body to the heart<\/li>\n\n\n\n
  2. Right Atrium<\/strong> \u2013 Receives deoxygenated blood<\/li>\n\n\n\n
  3. Tricuspid Valve<\/strong> \u2013 Blood flows through this valve<\/li>\n\n\n\n
  4. Right Ventricle<\/strong> \u2013 Pumps blood to lungs<\/li>\n\n\n\n
  5. Pulmonary Valve<\/strong> \u2013 Controls flow into pulmonary trunk<\/li>\n\n\n\n
  6. Pulmonary Trunk & Pulmonary Arteries<\/strong> \u2013 Carries blood to lungs<\/li>\n\n\n\n
  7. Right and Left Lungs<\/strong> \u2013 Blood receives oxygen and removes CO\u2082<\/li>\n\n\n\n
  8. Pulmonary Veins<\/strong> \u2013 Return oxygenated blood to heart<\/li>\n\n\n\n
  9. Left Atrium<\/strong> \u2013 Receives oxygen-rich blood<\/li>\n\n\n\n
  10. Bicuspid (Mitral) Valve<\/strong> \u2013 Blood flows into the left ventricle<\/li>\n\n\n\n
  11. Left Ventricle<\/strong> \u2013 Pumps blood into systemic circulation<\/li>\n\n\n\n
  12. Aortic Valve<\/strong> \u2013 Opens to allow blood into the aorta<\/li>\n\n\n\n
  13. Aorta<\/strong> \u2013 Distributes oxygen-rich blood throughout the body<\/li>\n<\/ol>\n\n\n\n
    \n\n\n\n

    6. What is an average normal adult blood pressure value?<\/strong><\/h3>\n\n\n\n

    Answer:<\/strong> 120\/80 mmHg<\/p>\n\n\n\n

      \n
    • 120 mmHg = Systolic pressure<\/strong> (pressure during heart contraction)<\/li>\n\n\n\n
    • 80 mmHg = Diastolic pressure<\/strong> (pressure during heart relaxation)<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      7. What is hypertension?<\/strong><\/h3>\n\n\n\n

      Answer:<\/strong>
      Hypertension<\/strong> is a chronic condition where the blood pressure is consistently higher than 130\/80 mmHg<\/strong>. It\u2019s often called a \u201csilent killer\u201d because it typically has no symptoms but can cause significant damage over time.<\/p>\n\n\n\n

      \n\n\n\n

      8. How does hypertension adversely affect the cardiovascular system?<\/strong><\/h3>\n\n\n\n

      Explanation:<\/strong>
      Hypertension puts increased pressure on artery walls<\/strong>, causing them to become thickened and less elastic<\/strong>, which can lead to arteriosclerosis<\/strong> (hardening of the arteries). The heart must work harder to pump against this resistance, which can cause left ventricular hypertrophy<\/strong> (thickening of the heart muscle). Over time, this can lead to heart failure<\/strong>, heart attacks<\/strong>, strokes<\/strong>, kidney damage<\/strong>, and vision loss<\/strong>.<\/p>\n\n\n\n

      \n\n\n\n

      9. List at least 3 risk factors for developing hypertension:<\/strong><\/h3>\n\n\n\n

      a. Obesity<\/strong> \u2013 Excess body weight increases strain on the heart
      b. High sodium diet<\/strong> \u2013 Increases blood volume and pressure
      c. Sedentary lifestyle<\/strong> \u2013 Lack of physical activity weakens the heart<\/p>\n\n\n\n

      Other possible factors: smoking, excessive alcohol, stress, genetics, and age.<\/p>\n\n\n\n

      \n\n\n\n

      10. What happens to the heart muscle during a heart attack?<\/strong><\/h3>\n\n\n\n

      Explanation:<\/strong>
      A heart attack (myocardial infarction)<\/strong> occurs when blood flow to a part of the heart muscle is blocked<\/strong>, often due to a clot in a coronary artery<\/strong>. This cuts off oxygen supply to the heart muscle. Without oxygen, heart muscle tissue begins to die<\/strong>. The longer the heart is deprived of oxygen, the more severe the damage. This damage can weaken the heart’s pumping ability<\/strong>, cause arrhythmias<\/strong>, or even lead to death<\/strong> if not treated quickly. Prompt medical treatment can limit the damage and improve survival<\/strong>.<\/p>\n\n\n\n
