The heart muscle, also known as the myocardium, is responsible for pumping blood throughout the body, and it needs a constant supply of oxygen and nutrients to function properly.]]> 2023-02-19 21:20:45 UTC https://padlet.com/gilliancasey307/5pde5e5r7x1nw784/wish/2487764953 What is coronary heart disease? gilliancasey307 https://padlet.com/gilliancasey307/5pde5e5r7x1nw784/wish/2487765311 Coronary heart disease (CHD) is a type of cardiovascular disease that occurs when the coronary arteries, which supply blood to the heart muscle, become narrowed or blocked due to the buildup of plaque (atherosclerosis).


When plaque builds up in the coronary arteries, the flow of blood to the heart muscle can be reduced or blocked. This can cause chest pain (angina), shortness of breath, and, in severe cases, a heart attack.


Risk factors for CHD include high blood pressure, high cholesterol, smoking, diabetes, obesity, lack of physical activity, and a family history of heart disease. These risk factors can damage the inner lining of the coronary arteries and promote the buildup of plaque.

When the heart contracts, blood is forced out of the left ventricle and into the aorta, which then sends the blood to the rest of the body via the arteries. This creates a pressure wave that can be felt as a pulse in certain arteries that are close to the skin, such as the radial artery in the wrist or the carotid artery in the neck.]]> 2023-02-19 21:47:34 UTC https://padlet.com/gilliancasey307/5pde5e5r7x1nw784/wish/2487774479 Procedure to investigate the effect of exercise on pulse rate of a human gilliancasey307 https://padlet.com/gilliancasey307/5pde5e5r7x1nw784/wish/2487776383 2023-02-19 21:52:39 UTC https://padlet.com/gilliancasey307/5pde5e5r7x1nw784/wish/2487776383 Learning Outcome: gilliancasey307 https://padlet.com/gilliancasey307/5pde5e5r7x1nw784/wish/2487793728 To dissect, display and identify the parts of the heart
