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

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