1. Why is excess salt bad for cardiovascular health?

  • Blood WP decreases as more water is stored, causing a rise in blood pressure and potential damage to small arteries.
  • Blood WP increases so the blood is able to flow quicker causing damage to the inside linings of arteries
  • Blood WP decreases so blood is less runny causing oxygen starvation in cells as blood cannot flow as well

4. CHD is a disease caused by excess energy intake. What happens to lead to the development of CHD?

  • Excess fats taken in get deposited along coronary artery walls leading to atherosclerosis. Blood flow is restricted and cells are starved of oxygen
  • Excess fats are deposited along coronary arteries and cause a blood to become restricted and so a clot forms blocking the artery
  • Excess fats are deposited along the coronary arteries and cause the artery to become narrower and less elasticated so blood pressure drops causing blood flow to be less effective
