  Pulmonary arteries carry deoxygenated blood
• What are the organs associated with the circulatory system?

  • Heart
  • Lungs
  • Liver
  • Kidneys
• What is coronary heart disease?

  When coronary arteries are blocked
• What causes coronary heart disease?

  Blockage of coronary arteries
• What can result from blocked coronary arteries?

  Heart attack
• What are the risk factors for coronary heart disease?

  Factors linked to increased likelihood of disease
• What is one risk factor for coronary heart disease?

  High cholesterol levels
• How does high cholesterol contribute to coronary heart disease?

  It leads to artery blockage
• What happens to arteries when they become narrowed?

  Blood flow is restricted
• How do risk factors affect a person's likelihood of developing coronary heart disease?

  They increase the chance of disease development
• What are the three main types of risk factors for coronary heart disease?

  1. Lifestyle factors (e.g., diet, exercise)
  2. Genetic factors (family history)
  3. Environmental factors (exposure to pollutants)
• What is the significance of understanding the circulatory system?

  It helps in diagnosing heart diseases
• Why is it important to know the names of blood vessels?

  It aids in understanding diagrams
• How can knowledge of the circulatory system help in medical emergencies?

  It guides treatment for heart attacks
• How do the lungs and kidneys relate to the circulatory system?

  They are organs that interact with blood
• What are the consequences of coronary heart disease?

  • Heart attacks
  • Angina
  • Heart failure
  • Arrhythmias
• What are risk factors for coronary heart disease?

  Many risk factors exist for coronary heart disease
• What are risk factors linked to?

  They are linked to increased likelihood of disease
• How do risk factors affect a person's health over time?

  They increase the chance of developing diseases
• What is a specific dietary risk factor for coronary heart disease?

  A diet high in saturated fat
• What can a diet high in saturated fat lead to?

  It can lead to fatty deposits in arteries
• How does smoking contribute to coronary heart disease?

  It increases blood pressure and damages arteries
• What is another risk factor for coronary heart disease?

  Being inactive
• How does inactivity affect blood pressure?

  It can lead to high blood pressure
• What is the relationship between inactivity and fatty deposits?

  Inactivity can lead to fatty deposits forming
• What is the name of the circulation system mentioned?

  Named after Sir Q. Lation in 1821
