Document Summary
Greater and faster absorption for immediate effect: obesity is a risk factor for development of hypertension. Especially abdominal obesity cause by inadequate exercise and excessive consumption of food. Cad disease is an impairment of the coronary arteries usually caused by atherosclerosis. Cad occurs when atherosclerotic plaque builds up in the walls of the coronary arteries. Plaque accumulation can be accelerated by smoking, high cholesterol and diabetes mellitus. Insufficient oxygen to meet the metabolic demand of the heart. Increase physical activity requires more mvo2: list five risk factors for cad, and explain why they contribute to potential development of cad. Hypertension: mechanical stress with increase pressure in the arterial wall causing damage of the endothelium lining promoting the entry of ldl in the intima. Smoking: produce toxins that irritates and damage the endothelial lining and increases clotting. Also, high triglycerides are associated with low hdl. Age: male >45 and female >55. on ageing, arteries harden due to thickening of the inner layer.
