📌 Heart Blood Supply: The heart itself is an organ that requires oxygenated blood. This blood doesn't come from the heart's chambers but rather from coronary arteries branching off the aorta.

• Right Coronary Artery - Supplies the right side of the heart.
• Left Coronary Artery - Splits into two branches, supplying the left anterior and left posterior heart regions.

💡 Fun Fact!: Imagine your heart as a city. The coronary arteries are the major highways ensuring all neighborhoods get their supplies.

📌 Atheroma (or Plaque): Fatty deposits in coronary arteries.

• Made up of different lipids, including cholesterol.
• Restricts blood flow to heart muscles.
• Symptoms include chest pain (angina) or shortness of breath, especially when you're jogging or climbing stairs.

📌 Potential Consequences:

• Blood Clot Formation: Rough artery walls from calcium salts can lead to blood clots.
• Heart Attack: When a blood clot blocks an artery, parts of the heart don't get oxygen and stop contracting.
• Tissue Death & Damage: Prolonged blockage leads to heart muscle tissue death, known as myocardial infarction.

💡 Real-world Example!: Consider a city's traffic system. If a major road gets blocked, traffic jams can cause chaos. Similarly, blockages in coronary arteries can cause significant health issues.

📌 Hypertension & CHD: High blood pressure is a major CHD risk.

• Systolic Pressure: Max pressure after heart contracts.
• Diastolic Pressure: Min pressure before heart contracts.

💡 Quick Tip!: The higher your blood pressure, the higher your risk. So, it's essential to keep those numbers in check!
